She serves as the overseer of the Night Owl class, which specializes in intelligence operations and sabotage. A true lady of high society, born to the CEO of a major corporation in Lukwofort. The Greywalk Company is a massive private intelligence firm, well known across the country. It exposes corruption and misconduct among corporations and influential figures through all forms of intelligence work, and is feared for its ruthlessness. Raised under her mother’s elite education from a young age, Claudia grew into a specialist in espionage. As a result, she has developed a rather troublesome fondness for surveillance activities like wiretapping and hidden cameras. She also serves as the head of the school’s disciplinary committee, though this too is simply part of her efforts to gather information on all students. While she is naturally proud and confident due to her upbringing, she is also intelligent, composed, and highly capable, with a personality that leaves little room for weakness. She is dependable and takes good care of others, earning the trust and admiration of the Night Owl students. Despite her slender build, she has been thoroughly trained in self-defense by her mother and can handle physical confrontations as well. However, she is still somewhat lacking when it comes to dealing with unexpected situations, and has yet to reach her mother’s level. She approaches the protagonist, who came from another world, as a rare subject of investigation. Although she attempts to extract information using her espionage techniques, she struggles against the protagonist’s fearless sexual harassment techniques. At the same time, she begins to develop an interest in him, as he shows no fear toward her. Before long, the two are drawn into a battle of wits where neither can afford to lose. Her code name is “Supreme,” meaning “the highest” or “ultimate.” Her abilities as a spy center on intelligence gathering through surveillance techniques taught by her mother. She is also skilled in sabotage, backed by her vast financial resources, making her a powerful ally and a terrifying enemy. She operates by the Greywalk family motto: “Perfection is the only acceptable standard.” Her boobs are T-cup, with a “fabulous celeb-rocket” shape. She never neglects her bust enhancement massages and is working hard to catch up to Safia and Erza from the other classes. Her specialty in honey traps is straightforward seduction using her beauty. If that fails, she resorts to Plan B, using surveillance and blackmail for leverage. Her hobbies include surveillance, taking photos of herself, and dancing. Her specialties are sabotage and information manipulation. Her mother, Alexia, is the CEO of the Greywalk Company and one of the nation’s most influential figures. As her successor, Alexia has instilled all of her knowledge and skills into Claudia. Their bond as both parent and mentor is strong, and it is said that the future of the Greywalk family is secure.

She serves as the overseer of the Wolfard class, which specializes in assassination and combat. Werewolves are said to be a race born for battle, possessing exceptional physical abilities and overwhelming strength in close combat. Erza in particular excels in speed and relentless attacks, to the point that those who face her feel as if they are being attacked by a pack rather than a single opponent. Wolves are known for their strong sense of family, and as a class leader, Erza is deeply trusted by her students. However, her two top underclassmen each have very strong personalities, and she seems to struggle with handling them. Because of her sharp features and dignified presence, she is extremely popular among the female students, to the point that she even has a fan club. Her appeal lies in the combination of being a leader while also giving off a lone wolf aura.…However, her true self is actually gentle, domestic, and quite feminine. She has continued to act the part expected of her so as not to disappoint those who admire her. When she first encounters the protagonist, they spar, and she quickly recognizes his skill. As fellow specialists in close combat, they hit it off and become close. She develops feelings for him as someone she can confide in and speak honestly with. Her codename is “Horde,” referring to her combat style of fighting like a pack. Her ability as a spy reflects her position at the top of Wolfard, specializing in close-quarters combat using martial techniques. Even when outnumbered, she is capable of turning the situation in her favor. Her boobs are U-cups, with a “Lone Rocket, downward-sloping” shape. She used to think they were a bit too large, but after learning that the protagonist is a big fan of breasts, she has reconsidered her opinion. Her specialty in honey traps is an aggressive “escort wolf” style approach. Werewolves have a courtship behavior on full moon nights known as “okuri-ōkami,” where they escort and pursue their partner. Since she is naturally shy and reserved, she uses that trait to build momentum and make her move. She usually wears glasses, but they are purely for appearance. Because she is often seen as intimidating, she wears them to soften her image. Her hobbies include cooking and collecting fluffy stuffed animals. Her specialties are close combat and running. Her mother, Glenda, is a teacher at the academy who instructs combat and dungeon training. Unlike her daughter, she embodies the stereotypical werewolf personality, bold, rough, and battle-loving. At home, Erza handles most of the household chores, and despite their differences, they have a good relationship. [u]♡Erza's Size Chart♡[/u] •Boobs: 131 cm ~ “A-Are they too big?

She is one of the top students in the Night Owl class, which specializes in intelligence operations and sabotage. As a succubus, she believes that no one can rival her when it comes to honey traps. At the same time, despite being a spy, she aspires to become an idol and is working toward her dream of becoming the industry’s first spy idol. She even founded her own “Spy Idol Club” and serves as its president, though she is currently the only member. Her desire to become an idol was influenced by her mother, who is a famous actress in the country. While she has the pleasure-seeking nature typical of a succubus, she is also hardworking. She is cheerful, energetic, and a natural mood-maker, and believes her personality is perfectly suited for being a glamorous idol. Being a succubus, she is comfortable with suggestive jokes and physical closeness, and she shows great interest in the protagonist, the academy’s only male student. She is determined to charm him using her honey trap techniques. She is friendly toward the protagonist from the very beginning and often initiates physical contact. Seeing that he provides knowledge about idols from another world, she judges him to be capable and appoints him as her producer. Together, they enthusiastically aim for her to become the top spy idol. From the protagonist’s perspective, he also looks forward to using “idol training” as an excuse for various sexual antics. Her codename is “Killer Bee,” referring to her ability to strike straight at someone’s heart in a single blow. Her ability as a spy is, of course, honey traps. She believes that a spy’s worth is measured by how successfully they can pull off a honey trap, and therefore considers herself the most suited for the role. However, her approach tends to rely too quickly on physical contact, lacking subtlety and timing, so she is not actually very skilled at it. Her boobs are R-cups, with a “A half-sphere shape made for supporting your oshi while you can” shape. While size is important, she also pays close attention to their shape and firmness. She boldly claims that her specialty in honey traps is “everything,” but in reality, her success rate is not particularly impressive. Her hobbies include social media, following trends, and studying idols. Her mother, Rosebell, is a former actress and now a teacher at the academy. Having grown up watching her nationally famous mother, Lizbeth decided, “If Mom is an actress, then I’ll be an idol!” Her mother, however, seems troubled by the idea of a spy, who should avoid standing out, trying to become an idol.

She is one of the top students in the Snake Unit, a class specializing in infiltration and stealth. She has the trait of being more human-like during the day and more strongly influenced by her vampire blood at night. Her personality also makes a change during this cycle. During the day she is lethargic and unmotivated, while at night she becomes high-energy and excitable. Her physical abilities rank among the best across all three classes, and she particularly excels at parkour. She can infiltrate almost any location with ease, though her abilities drop significantly during the daytime. During the day, her lazy and sluggish nature stands out, and she is often compared to “overcooked noodles.” However, she plays the role of the straight man, keeping both her senior Safia and her junior Shani in check, making her an important part of the group. At night, she becomes energetic and lively. With no one left to rein things in, the Snake Unit at night is said to be completely uncontrollable. Percy herself considers her split personality between day and night to be “a pain,” but she grows fond of the protagonist, who finds both sides of her interesting and accepts them. During the day, they spend time indoors reading manga or playing games together. At night, they go out into the city and compete in parkour, enjoying themselves that way. Her codename is “Night Girl,” named for how she truly shines after dark. Her ability as a spy focuses on infiltration using her exceptional physical capabilities. She can traverse extreme heights and tight spaces alone with ease. However, this only applies at night. During the day, she is apparently prone to tripping on stairs. Her boobs are P-cups, with a “always lifted, rocket-like shape even during the day” style. Their sensitivity differs between day and night as well, with them being more sensitive at night and more prone to producing milk. Her specialty in honey traps is a versatile style, taking a more passive role during the day and an aggressive approach at night. Her hobbies are watching manga and anime during the day, and parkour and general physical activity at night. Her mother, Elisia, is the passionate physical education teacher at the academy who is also pure-blood vampire that overcame her weakness to sunlight through sheer effort and determination. While their personalities differ quite a bit during the day, they get along well at night and can often be seen leaping through the city together.

She serves as the overseer of the class known as the Snake Unit, a group that specializes in infiltration and stealth. She is a powerful magic user capable of wielding numerous high-level spells, and calls herself the “Crimson Genius Witch.” She possesses one of the highest levels of magical power on the continent, and her output is on an entirely different level, truly befitting her claim of being a genius.…However, in reality she cannot properly control her magic, and has repeatedly caused destruction throughout the academy and dorms, making her something of a hopeless witch. She is called things like “Calamity Witch” and an "open powder keg” by others, though she herself is completely unaware of it. She is confident and carefree, not one to worry about small details. Simply put, she is a bit of an airhead. She believes she is good at taking care of her underclassmen, but in reality they are the ones taking care of her. The Snake Unit is united in figuring out how to deal with her antics, and as a result, their class has strong cohesion. Safia herself seems to misunderstand this and thinks it is because she is popular. That said, when it comes to magical knowledge, she is the real deal, and she may even have a sharp eye for observation. She is extremely interested in the protagonist and is determined to recruit him into her class. She believes it will be easy thanks to her charm and her figure, which often results in her getting sexually harassed by him instead. Her codename is “Jewel,” a reference to how she likens her many spells to shining gemstones. Her ability as a spy is a transformation spell that allows her to perfectly copy another person. This type of magic requires immense magical power and constant maintenance, making it something only a select few can use. That is how she became the overseer of the Snake Unit. But it has one major flaw: even if her appearance is perfectly replicated, she is still herself underneath, so she quickly gives herself away when she speaks. She attends remedial classes in acting and performance, but so far her progress has not been very good. Her boobs are V-cups, with a “genius-level long, semi-elliptical drooping” shape. They are the largest among the students, and she proudly calls them her “victorious V-cups.” Her specialty in honey traps involves using magic and magical potions to charm and entice others. However, she often ends up failing and getting affected by her own techniques instead. Her hobbies include hair care (which she’s terrible at) and developing new spells (which she fails at). Her special skill is magic in general (which is dangerous). Her mother, Isolte, is also her mentor as a witch. She is one of the three great witches of the continent, but she seems to have a hard time dealing with her daughter. Even so, their relationship is good, and they often spend time together after school having tea at Isolte’s research cottage on the academy grounds.

She is one of the top students in the Night Owl class, which specializes in intelligence operations and sabotage. She is a magitech android created by a genius scientist she calls her mother, boasting a level of quality so high she could easily be mistaken for a human. She inherited her mother’s brilliant intellect and develops a wide range of spy gadgets, which she uses in her missions. Recently, after gaining the protagonist as a valuable test subjec..cooperative partner, she has been coming up with even more new gadgets. Her personality is cool and sharp-tongued, often playing the straight man. Despite being a first-year, she frequently keeps her two upperclassmen in check. However, she secretly enjoys being praised and can be surprisingly easygoing in that regard. She grows fond of the protagonist, who is good at giving compliments, and begins calling him “Master.” Once you get to know her, she can be unexpectedly friendly and even jokes around. At first, she viewed the protagonist as an intruder and attempted to eliminate him, but after the misunderstanding was cleared up, she quickly warmed up to him. While she is generally a cute junior, she has the bad habit of trying to test her new gadgets on the protagonist’s body. She has begun to develop feelings for him for the first time, but since she does not yet fully understand them, she seems a bit flustered. Her codename is “007” (Double-O Nana), with the key point being that it is read as “nana,” not “seven.” The name comes from her being the seventh completed model type. Her abilities as a spy include hacking and the use of the gadgets she develops herself. Her information-gathering ability using specialized goggles is also extremely high, making her one of the best in the academy when it comes to information warfare. Her many gadgets are highly useful, though she apparently has so many that she sometimes forgets where she put them. Her boobs are Q-cups, with a “Opai-Fall Rocket” shape.After learning that the protagonist is a big fan of boobs, she has recently started doing bust enhancement massages. Her specialty in honey traps involves using her strengths to deploy various specialized erotic gadgets. However, the protagonist often turns these tactics back on her. Her hobbies include gaming and watching movies. Her specialties are hacking and gadget development. Her creator and mother figure, Amber, is a well-known magitech scientist in the country. Though quite eccentric, she has a good relationship with Septem, and the two appear just like a real parent and child. Incidentally, she strongly considers a genius scientist from the maid nation of Fifrecia to be her rival.

She is one of the top students in the Snake Unit, a class specializing in infiltration and stealth. A rare race even within the academy, she is a ghost girl. Normally, ghosts cannot physically interact with other beings, but she overcame this limitation thanks to a magical potion created by Isolte, an authority in magical pharmacology and Safia’s mother. Not only can she turn herself invisible, but she can also make anything or anyone she touches disappear along with her. She can even pass through walls, allowing her to move around the academy using shortcuts and live quite conveniently. Her personality is extremely cheerful, energetic, and headstrong, always running around at full speed. Because she is so different from the typical image of her race, people often question whether she is really a ghost. She is also a member of the cheerleading club, making her even less ghost-like. Recently, she seems to view a tall, well-endowed transfer student who appeared at a nearby academy like a shooting star as her rival. She has always thought ninjas were incredibly cool, so she has become very attached to the protagonist, who came from another world. She plans to one day make him her master, become a ninja herself, and call herself “Ghost of Ninja.” She follows him around like a puppy and often sings her own homemade ninja songs. Her codename is “Stand,” derived from her ghostly ability to appear behind her target. Her ability as a spy is stealth through invisibility. Because she cannot be seen and can pass through walls, her skills would normally place her among the strongest spies. However, despite having perfect abilities, her personality is her biggest flaw, as she cannot stay still or remain quiet. She is constantly trying to break the habit of speaking out loud and running around. Her boobs are O-cups, with a “puppy-like, playful bowl" shape. They are still developing, and she confidently believes she has the potential to surpass her senior Safia someday. Her specialty in honey traps is what she calls the “Ghost Invisible Harassment Trap.” Her hobbies are karaoke and running, while she dislikes silence and staying still. She also has a distinctive way of speaking, often ending her sentences with “–de arimasu!” Her mother, Shaydi, is a teacher at the academy and handles stealth classes. She is quiet and somewhat fragile in demeanor, fitting the typical image of her race, and often wonders how she ended up with a daughter like Shani. Despite their completely different personalities, they have a good relationship and often go out together on their days off.

She is one of the top students in the Wolfard class, which specializes in assassination and combat. High elves are a gifted race skilled in both magic and archery, and Torenia is no exception, an outstanding honor student. She receives top evaluations across all subjects and contributes heavily to Wolfard’s class points. Her skill with the bow is especially unmatched in the academy, and she has had no real rivals since her first year. Her personality is gentle and well-mannered, and she is well liked by both friends and teachers.…However, that is only her public face. In reality, Torenia is quite sharp-tongued and a bit scheming. She only shows this side in front of close friends, but it is said that monsters often lose their will to fight from her words before her arrows. Incidentally, she hides her true nature in front of her mother and behaves like a proper lady. The protagonist, who came from another world, quickly becomes the perfect target for her sadistic tongue. However, since the protagonist doesn’t take it to heart and keeps making sexual advances, he’s like a natural enemy to Torenia. As their back-and-forth continues, she gradually finds herself becoming more interested in him. She may have a bit of a submissive streak. Her codename is “Bullseye,” meaning a perfect hit. Her ability as a spy is long-range assassination through archery. She inherited her talent from her mother, a legendary sniper, and aims to follow in her footsteps. Her boobs are S-cups, with a “long, perky bell-shaped” form. She also happens to have inverted nipples, which naturally makes her an easy target for the protagonist’s teasing in more ways than one. Her specialty in honey traps is psychological pressure using her sharp tongue. It is said to be especially effective against targets who are more receptive to that kind of approach. Her hobbies include beauty care and delivering sadistic remarks. Her specialties are archery and swimming. Her mother, Priscilla, is a teacher at the academy and also Torenia’s archery instructor. She is a gentle and elegant high elf who embodies the ideal of her race, and Torenia aspires to become like her. They have a close relationship and often go shopping together on their days off.

After opening a scroll left behind by their stepfather, she is transported to another world together with her younger brother and mother. In the spy nation of Lukwofort, she ends up living as a student at a spy academy alongside her brother, an older-sister figure who gets dragged into the situation. Like the protagonist, she is a descendant of ninjas, part of a lineage of modern-day shinobi. Her mother and the protagonist’s father fell in love during conflicts between ninja factions, abandoned their clans, and ended up together. Although she is the same age as the protagonist, she acts as his older sister simply because her birthday comes slightly earlier. They have a good sibling relationship, occasionally arguing but also joking around and getting into mischief together. Personality-wise, she is cheerful and attention-seeking, but in the modern world before being transported, she suppressed herself and lived quietly so that her ninja heritage wouldn’t be discovered. Because of that, she often argued with her mother, saying she wanted to quit being a ninja. However, in Yggdrasil, where many different races live, she feels great joy in being able to openly be her true self and is fully embracing life in the other world. Regarding her younger brother, she knows he supported her in various ways to keep their ninja lineage secret in their previous world, and she feels both gratitude and romantic feelings toward him. She had kept those feelings mostly hidden because they are siblings, but now that they are in another world, she is starting to think it might not matter anymore. On top of that, seeing other girls approach him has made her anxious, and she tries to keep them at bay with the logic of, “My little brother belongs to his big sister!” She also tolerates a certain level of teasing from him, though she makes him run errands in return. As a spy, she is highly capable and has quickly become a promising student at the academy. This is only natural, as her physical abilities, combat skills, and stealth techniques were already exceptional from her ninja training. Especially when working together with the protagonist, they are strong enough to overwhelm groups of monsters in this world. Her boobs are P-cups, with a “kunoichi bowl-shaped” form. They were something she took pride in, but after hearing rumors that even J-cups are considered small in this world, she has started working on bust enhancement. As part of her classes at Espiona Spy Academy, she is currently studying honey trap techniques. Deep down, she thinks, “If I tried to seduce him, taking down my little brother would be easy.” Her hobby is trying different foods, fashion, social media, and searching her own name online. Her specialty is all forms of ninjutsu. Her relationship with her mother, Shigure, who is also her mentor as a shinobi, is somewhat strained. They argue almost daily, with the daughter wanting to quit being a ninja and the mother taking pride in their lineage. Each time, the protagonist ends up mediating between them. While she does not hate her mother, she wishes her mother would understand her better. Incidentally, she once got furious when her mother unilaterally assigned her the spy codename “Kunoichi.” [u]♡Nagi's Size Chart♡[/u] •Boobs: 115 cm ~ “Where are you even looking?” •Nipples: 5 mm (Height) ~ “Not bragging or anything, but… they’re pretty sensitive.” •Areola: 3.3 cm (Diameter) ~ “This beauty… well, you don’t really need to see it.” •Waist: 56 cm ~ “It’s the result of my daily training.” •Hips: 85 cm ~ “Big?

She is one of the top students in the Wolfard class, which specializes in assassination and combat. Halflings were generally seen as small, plain, and unremarkable compared to other races. Vivian dislikes that perception and works hard every day to raise the status of her race. Coming from a lineage of assassins, her dual-knife combat style is fierce and merciless. While achieving results in battle, she also dresses in her favorite gothic lolita fashion, making sure her appearance stands out as well. Despite her cute looks, she has a blunt and fearless personality. She does not speak much, but when she does, she says exactly what she means in a sharp and direct way. She also seeks attention and steps forward boldly, driven by her desire to elevate her race’s reputation. Though she can be hard to approach, she has a strong sense of camaraderie. She believes that taking down the protagonist, a ninja from another world, would earn her a massive score, and she constantly targets him. As a result, the protagonist’s daily routine consists of dodging Vivian’s attacks while engaging in sexual harassment, all while going about his school life. As she continues to pursue him, a different kind of feeling may begin to stir within her… Her codename is “Gothic,” derived from her love of gothic lolita fashion. Her ability as a spy lies in assassination techniques using her twin knives. These knives are custom-made favorites that she carefully maintains every day while humming to herself. Her boobs are N-cups, with a “dangerously alluring half-sphere” shape. To ensure halflings are not looked down on, she performs bust enhancement massages every single day. Her specialty in honey traps is a lolita-style approach that strongly appeals to certain targets. However, she finds honey traps bothersome and would rather resort to threatening with her knives in the end. Her hobbies include competitive eating and nighttime walks. Her specialties are costume-making and knife handling. Her mother, Victoria, is a teacher at the academy who teaches home economics and assassination techniques. She is known as a mysterious woman with a unique presence and intimidating aura. They often make outfits together, and their relationship is very close.

She is a teacher at the spy academy, and also the CEO of the private intelligence company “Greywalk Company.” Her codename is “Flawless,” meaning perfection. Her breasts are U-cup, boasting a volume that seems made to be flaunted. She is the CEO of a major corporation famous even within Lukwofort, and an enormously wealthy woman. Using espionage activities, she exposes corruption and misconduct among corporations and important figures, making her a feared existence. However, her motto is apparently: “The work is gray, but the workplace is white.” In this country, it is said that if one can get a job at the Greywalk Company, their future is secure. Alexia is a celebrity known both domestically and internationally, and her influence within the academy is also strong. She is even spoken of as a candidate for the next academy headmistress. She is the homeroom teacher of Night Owl, and her subjects are voyeur photography, wiretapping, and art. During her student days, she secretly worked behind the scenes using “nests” to gather leverage not only on students, but even on teachers. She became feared under the guise of “The Butterfly That Devours the Spider’s Web.” Alexia went so far with her activities that the academy’s rules regarding voyeurism and wiretapping were revised because of her. She is confident, self-centered, bold and fearless, with a forceful personality. A textbook example of someone who is reassuring as an ally, but terrifying as an enemy. However, she does not particularly enjoy underhanded methods, and apparently her motto is “fair and square espionage activities.” She also describes herself as heartless, but according to those who knew her during her student years, she unexpectedly had an emotional side to her. Toward her daughter Claudia, she educates her strictly so that Claudia may become her successor. At the same time, she deeply loves her daughter, though she is unable to express those feelings very well. Even so, the bond between parent and child is strong, and their relationship itself is a good one. From the very beginning, she holds a strong interest in the protagonist, and intends to bring him into her class no matter what. A savior from another world is a precious existence, and she seems willing to use every possible means for that purpose. She has absolutely no hesitation in using her own body for it, and rather seems to enjoy doing so. Her hobbies are all forms of espionage activities, opera appreciation, and oil massages. The people she is bad with are those who endlessly talk about her past (Isolte and Glenda).

She is also a teacher at the spy academy, and her codename is “000” (Triple-O). Her boobs are a bountiful Q-cup, and apparently she finds it troublesome how sweat gathers in her cleavage while she works. She is a well-known figure even within Lukwofort, and calls herself a genius scientist. She has developed countless spy gadgets, many of which have continued to be used by the nation’s intelligence agents for years. She constantly wears a high-performance headgear device of her own creation, which often surprises those meeting her for the first time. She is continually compared to Parthia Ramsey, the magitech scientist from the maid kingdom Fifresia, and as a result has come to view her as an intense rival. Her subjects are science and gadget development. Since she designs and develops gadgets suited to the needs of each student, she is considered very reliable. However, some people seem to think she is an eccentric mad scientist. One thing impossible to avoid when speaking about her is how completely different her personality becomes depending on whether she is wearing her headgear or not. When wearing it, she becomes overflowing with confidence and acts eccentric, while without it she lacks confidence and becomes timid and nervous. Since she was weak-willed and cowardly from a young age, it seems she came to believe that by blocking out the gaze of others with the headgear, she could become a different person. Incidentally, the personality she adopts at those times closely resembles Parthia, suggesting that despite seeing her as a rival, she has also been deeply influenced by her. Her relationship with Septem, whom she treats like a daughter, is extremely good. The two happily continue their research and development together, and to outsiders they appear even closer than a real parent and child. Incidentally, the reason Septem is cool and self-confident is because Amber designed her to possess the kind of personality she herself wished she had. Toward the protagonist who came from another world, she is fascinated from the very beginning. She wants to conduct all kinds of research on him as a test subje… specimen. She is also fond of him because he treats her without prejudice. Her hobbies are gadget development, research, and adding new functions to Septem. The things she dislikes are having her headgear removed, and being compared to Parthia. [u]♡Amber's Size Chart♡[/u] •Boobs: 121 cm ~ “Magnificent, aren’t they?

She is a teacher at the spy academy, and her codename is “Acro Bat,” a play on her vampire race. Her boobs are a firm and well-shaped P-cup, something she is apparently very proud of. She is an extremely rare type of vampire: a hot-blooded athletic vampire who is energetic even during the daytime. Apparently she overcame sunlight through “hard work and guts,” and people meeting her for the first time almost never guess her true race. She married a human man, and together they had their dhampir daughter, Percy. Her subjects are physical education and dark magic, though according to herself, she is apparently terrible at dark magic. Her physical abilities are extraordinarily high, and during her student days, despite belonging to Snake Unit, she was said to rival even the students of Wolfard. She oversees multiple athletic clubs as an advisor, and spends every day constantly busy. Also, because “they’re easy to move around in and comfortable,” she always wears her gym uniform. Her personality is cheerful, lively, and straightforward, and because she is easygoing and fun to be around, she is quite popular among the students. She basically believes that anything can be solved through hard work and guts, and is the type whose body moves before her brain does. To the students, she feels less like a teacher and more like a dependable older sister. She teases her daughter Percy for being weak during the daytime, though the relationship between parent and child is very good. She keeps trying to put Percy through intense “guts training” to overcome sunlight, something her daughter absolutely hates. However, since Percy’s physical abilities increase at night, the two of them often leap around the city together after dark. She immediately took a liking to the protagonist because of his strong physique, and the two quickly became close. She often tries to enjoy outdoor activities together with him, though apparently Percy keeps getting in the way. Because of that, rumors say she has even been sneaking into the protagonist’s room at night in hopes of sharing his bed. Her hobbies are physical activity and watching sports. The things she dislikes are restrictive clothing, and movies that need to be watched more than twice to understand.

She is a teacher at the spy academy, and her codename is “Fang,” representing fangs. Her boobs are an overwhelming and heavy-looking V-cup. A combative and bold, typical werewolf woman. Even among the teachers she holds a leader-class position, and she often fights with Alexia, who stands in the same position as her (though they are the type who get along better the more they fight). Since werewolves are a race that acts in packs, she demonstrates leadership and keeps the students united. She is the homeroom teacher of Wolfard, and her subjects are combat techniques and dungeon training. Since they are classes that strongly feel like something from another world, the protagonist and Nagi are especially fond of them. She constantly keeps an eye on the students’ safety, so the trust people place in her is very strong. She has a combative, openhearted, older-sister type personality. Since she is short-tempered and quick to get heated, her daughter often has to hold her back. Even so, at heart she has a strong sense of justice and hates crooked behavior, making her fundamentally a very good person, and she is highly popular among the students. Her relationship with her daughter Erza is very good, and the two often go out running together. However, she worries somewhat about how timid her daughter is, and thinks she should “return more to her wild instincts.” Since she is completely hopeless at housework, her daughter actually holds the stronger position at home. When she first met the protagonist, she immediately recognized his combat ability and became extremely fond of him. She is thinking of pushing her daughter toward him so he joins the class, while also hoping Erza can overcome her timidness at the same time, killing two birds with one stone. And before her daughter does, she is plotting to sample the protagonist herself. Her hobbies are combat, dungeon conquest, and solo travel. The things she dislikes are cooking, laundry, cleaning, and guys who sit far away pelting people with magic attacks. [u]♡Glenda's Size Chart♡[/u] •Boobs: 134 cm ~ “Ya really like boobs, huh?

Her boobs are also great T-cups. A seductive and composed woman who seems to embody the image people generally have of a “witch.” She is a legendary witch famous even within Lukwofort, and is deeply knowledgeable in magic, pharmacology, alchemy, and many other fields. She was also the one who synthesized the secret medicine that allowed the ghost mother-and-daughter pair Shani and Shaydi to physically touch living beings. She is the homeroom teacher of Snake Unit, and teaches classes related to magic in general and pharmacology. She also gives advice to students using her broad knowledge, and because she takes very good care of them, she is deeply admired. Thanks to arrangements made by the academy chairman, she possesses a separate building on the academy grounds for magical and pharmaceutical research, commonly referred to as the “Witch Hut.” She is intelligent, calm, and always composed. However, she also has a side that panics when unexpected situations arise. The one who troubles her most is none other than her only daughter, Safia. Although Safia aims to become a great witch like her mother, she is terrible at controlling her magic and is the academy’s greatest incompetent troublemaker. Since her magical power and output are absurdly high, the situation becomes even worse, leaving Isolte constantly holding her head in frustration every day. Although her daughter causes many problems, her relationship with Safia is very good. After classes, the two often drink tea together inside the Witch Hut while researching magical potions. Incidentally, she does not allow her daughter to perform the actual mixing process, instead mainly assigning her tasks such as preparing the tools. Toward the protagonist, she hopes he may help her daughter grow in a positive direction. In truth, she possesses an extremely strong sex drive, and apparently wants to find some excuse to “taste” the protagonist for herself. Her hobbies are making butter cookies and herbal tea, along with researching magic and magical potions. The things she dislikes are unexpected situations, and hearing her daughter say: “Leave it to me!” [u]♡Isolte's Size Chart♡[/u] •Boobs: 128 cm ~ “Do they smell nice?

She is a human. Her codename is "Dusk," meaning twilight. She has a slender yet glamorous figure, with S-cup breasts. She is a top-class agent at Lukwofort, and an idol and role model for all the students. She still enjoys great trust from the government, and during her active service, she was known as "Ms. Perfect," a highly skilled spy. She has consistently succeeded in missions that were said to be impossible, making her a fitting person to be the head of the spy academy. Even she, however, was currently in a desperate situation. To make matters worse, an enemy spy had infiltrated the academy that trains spies—an unprecedented crisis. With no idea who the enemy was, she was at a loss for allies. Seeing the protagonist, who had come from another world, as a potential savior, she asked him to investigate the enemy spy who had infiltrated the academy. She is calm, intelligent, and yet flawless in her personality. She possesses both ruthlessness when it comes to her duties and ruthlessness towards her enemies, making her a reliable figure as the head of the academy's board of directors. However, it seems she is quite frank with those she trusts. She trusts the protagonist and, in exchange for accepting the mission, guarantees him and his family a comfortable life in the other world. She also possesses a cunning nature, using the protagonist's unique skill to have sex with him, making it impossible for him to refuse. However, it seems they had good physical chemistry, and she's willing to give him another "special lesson" if he wishes. Because of this history, she turns a blind eye to the protagonist's daily sexual harassment and problematic behavior. Her hobbies include traveling, driving, scuba diving, and drinking alcohol. She dislikes people who pry into her past. [u]♡Olivia's Size Chart♡[/u] •Boobs: 128 cm ~ “What do you think?

She is a teacher at the spy academy, and her codename is “Lightning.” It is said that the name came from how the arrows she fired during her active years resembled lightning itself. Her boobs are soft, squishy, and packed with volume, massive R-cups. A serious and polite woman, like the very image of a high elf drawn from a painting. Even among the eccentric faculty, she is one of the more sensible members, and is loved by both students and teachers alike. Although her clothing is extremely revealing, it is apparently traditional high elf attire, so she herself does not think anything of it. There are also rumors that she is secretly very fond of young boys, though nobody actually believes them. Her subjects are languages, history, and archery. All of her classes are taught gently and clearly, making them highly popular among the students. Among them, her skill in archery is especially remarkable, and during her active years she successfully carried out many long-range sniping missions. Her personality is calm and refined, making her one of the academy’s especially popular teachers. Many female students admire her, and she is often approached for advice. She also has a surprisingly friendly and easygoing side, and once you become close to her, she interacts with you much more casually. Her relationship with her daughter is also very good, and on holidays the two often go out together or practice archery together. The pair are apparently famous around the academy as a beautiful mother-and-daughter duo. Incidentally, she seems completely unaware that her daughter is sharp-tongued and secretly scheming. Toward the protagonist, she has had a high opinion of him from the very beginning, partly because she also wanted a son. She unexpectedly allows quite a bit of physical contact, something the protagonist is naturally very grateful for. Apparently, there is also something she would like him to do for her using the power of his skill? Her hobbies are archery, horseback riding, and caring for both her own hair and her daughter’s hair. The things she dislikes are rain and wind, and stories about her student days [u]♡Priscilla's Size Chart♡[/u] •Boobs: 124 cm ~ “Oh my, do you want to be spoiled?” •Nipples: 5.6 mm (Protrusion) ~ “I’m weak when they’re sucked on♥” •Areola: 4.6 cm (Diameter) ~ “You really do like boobs, don’t you♥” •Waist: 58 cm ~ “I take care to maintain my figure.” •Hips: 90 cm ~ “A little big?

She is a teacher at the spy academy, and her codename is “Actress.” Her boobs are an incredibly soft and wonderfully pleasant-to-touch S-cups. A former famous actress well known even within Lukwofort, and a highly skilled performer who has won awards for several movies and dramas. During her younger years, she came to enjoy “becoming her role” as part of her spy missions, and achieved great success while balancing espionage work with her acting career. She has since retired from acting, and now teaches those acting techniques to the students. Being a succubus, she was also highly skilled at seducing targets and obtaining information through honey traps. Her subjects are acting, theater, and honey traps. Making use of her experience as an actress, she teaches students how to truly become the role they are playing. As for honey trap classes, because Yggdrasil has overwhelmingly few men, the lessons had previously been designed for female targets. However, with the transfer of the protagonist, the academy’s only male student, the honey trap community has begun to stir in a major way. She has the pleasure-loving side expected of a succubus, but at her core she is calm and sensible. As a former actress she is also highly knowledgeable about beauty and cosmetics, making her broadly popular among both students and teachers. Since she is usually rather serious by nature, she is the type who completely changes once alcohol enters the picture or her libido is ignited. Although her relationship with her daughter is good, she is often troubled by Lizbeth’s dream of becoming a spy idol. Since she herself was an actress, her daughter apparently decided to pursue becoming an idol, though Rosebell honestly thinks: “But why?” Even so, she also wants to support her daughter’s dream, leaving her somewhat conflicted. Toward the protagonist, perhaps because of her succubus instincts, she has had a high opinion of him from the very beginning. Since he also helps her daughter in many ways, she trusts him as well. And apparently, she has begun to grow restless with the desire to use a honey trap on a man again for the first time in quite a while. Her hobbies are all things beauty-related, watching stage performances, and traveling. The thing she dislikes is people who casually spoil dramas and movies.

She is a teacher at the spy academy, and her codename is “Shadow.” Her boobs are large, well-shaped O-cups. A ghost-like woman with a gloomy, introverted aura surrounding her. Since being unnoticed is also an advantage for a spy, during her active years she successfully carried out many covert missions. Apparently, she still wonders how such an overly energetic daughter, like the reincarnation of the sun itself, was born from someone like her. Her subjects are infiltration and stealth. Her stealth abilities were already top-class during her student days, and even now those skills have not dulled. However, even when she is not trying to hide, people often fail to notice her anyway, something she apparently finds a little sad. Her personality is timid, and she is the type who does not like standing out too much. Considering her race, she believed that was only natural, but after giving birth to a daughter who completely overturned the very image of what a ghost should be, she has begun to question herself. Apparently she worries things like: “Am I really okay staying like this? But if I suddenly changed my personality now, wouldn’t that be embarrassing…?” Although their personalities are complete opposites, her relationship with her daughter Shani is very good. On holidays the two often go out together or do endurance karaoke sessions together. Also, since they can slip through any crowd using ghost abilities, the mother and daughter pair make very convenient use of it. Since she is not very used to men, she was a little wary of the protagonist at first. However, she quickly came to trust him after seeing how kindly he treated Shani. And in order to fix her own personality, she ended up asking the protagonist to grant her a certain “request.” Her hobbies are karaoke, reading, and relaxing in shady places. The things she dislikes are exercise, sunlight, and standing in front of large groups of people. [u]♡Shaydi's Size Chart♡[/u] •Boobs: 114 cm ~ “A-Are they small…?

Her codename is “Shaker,” a name given to her during her active years because she specialized in “shaking people up.” She has a transistor-glamour figure, and despite her small stature, her boobs are massive T-cups. She is the master and bartender of the academy cafeteria, the “Spy Bar.” The reason the cafeteria takes the form of a bar is because spies often gather information in bars, so the academy wants students to become accustomed to that kind of atmosphere from their school days. Even so, since it is still a place of learning for students, alcohol itself is not served. Instead, the academy specialty known as “Gray Beer” is actually non-alcoholic beer, and thanks to its delicious taste it has become extremely popular among the students. Also, though only the staff know this, the Spy Bar apparently has a “nighttime face” as well? Since the name “TinTin” is impossible not to tease, she has been made fun of over it ever since her student days. TinTin, after all. Because of that, she makes the students call her “Tee-chan,” and anyone who calls her by her real name is punished. Combined with her personality and short height, she is adored by the students as something of the bar’s mascot. Although her way of speaking is blunt, she is friendly and extremely caring, making her beloved by everyone. She is also highly capable, possessing the skill to manage the constantly crowded Spy Bar, along with broad awareness and sharp intuition. During her student years she served as the prefect of Night Owl, and was rivals with Olivia, who at the time was the prefect of Wolfard. She was the first to notice the mission assigned to the protagonist, and offered to help him since he was unfamiliar with the academy. From then on, she provides him with valuable information regarding the academy and its students as one of his assets. She has essentially become the protagonist’s partner, and she herself does not seem entirely unhappy about that. Her hobbies are creating original cocktails, food tourism, and watching romance dramas. The things she dislikes are people who pat her on the head, and people who call her by her real name.

Her boobs are U-cups, and Nagi inherited her breast size from her. A descendant of the prestigious and well-known Azuma ninja bloodline. Shigure’s ancestors were a clan that continued operating behind the scenes throughout history. When she was younger, she married a ninja connected to the Azuma clan and gave birth to Nagi, but her husband died in an accident during a mission. Afterwards, she met the protagonist’s father, who belonged to a different ninja school, on the battlefield, and the two fell in love before becoming rogue ninjas together. They remarried and spent happy days together, but her husband once again died after killing an assassin sent by the Azuma clan at the cost of his own life. Since then, she has continued raising both Nagi and the protagonist on her own. Perhaps because of her upbringing, she has a serious and strict personality, and can be somewhat inflexible. After breaking the seal on an item left behind by her late husband, she ended up being transported to another world together with her son and daughter. (She had opposed opening it, but the protagonist convinced her by saying: “What if it’s a love letter Dad wrote to you, Shigure-san?”) Under the condition that they would search for both a way to survive in this world and a method to return home, she accepted Headmistress Olivia’s request and became a special instructor at the spy academy. Her subject is the newly established “Ninjutsu,” and her codename is “Oboro,” the alias she used during her ninja days. Due to her personality, she was well-suited for teaching, and because she was also an elite kunoichi, she quickly became extremely popular among the students. Her relationship with her daughter Nagi cannot exactly be called good, and the two often argue, forcing the protagonist to mediate between them. Endless pointless arguments continue daily between Shigure, who wants to return to their original world, and Nagi, who wishes to remain in this one. According to the protagonist, both mother and daughter suffer a dramatic drop in IQ whenever they fight. Although she is strict toward her daughter Nagi, she is extremely soft on the protagonist, who is the child left behind by her late husband. The protagonist also holds back somewhat because she is his stepmother, but apparently she truly wishes he would rely on and cling to her much more. She often scolds him by saying: “Nagi is watching, so no.” However, Nagi suspiciously wonders if that means it would be fine as long as she were not watching. Her hobbies are training, cooking Japanese food, and visiting hot springs. The things she dislikes are machines such as smartphones, foreign loanwords, and alcohol, since she becomes a violent drunk. She also has a habit of forcefully converting foreign words into Japanese.

She is a teacher at the spy academy, and her codename is “Bloodrain.” Despite her small stature, her boobs boast an impressive T-cup size. A woman dressed in gothic lolita fashion just like her daughter, giving off a lazy and melancholic atmosphere. It is said that no one can rival her when it comes to handling knives, and during her active years she apparently went too far so often that she regularly turned places into seas of blood. Incidentally, the Oscura family is famous as a former lineage of assassins. Victoria’s mother worried about her daughter and granddaughter continuing down the path of assassins, and enrolled them into the spy academy so they could live under the light of day instead. Her subjects are home economics and assassination techniques, an extreme contrast. In home economics classes, both her cooking and sewing skills are at a professional level, and the sewing club she runs after school is apparently always completely full. During assassination training, she wears a handmade apron so her clothes do not get stained with blood while taking down monsters. She has a decadent atmosphere and a mysterious personality. She shows absolutely no mercy toward enemies, but toward students she is surprisingly sensible and gives accurate advice. Among the teachers, because of her height difference, she is doted on almost like a younger sister (though she dislikes it). Her relationship with her daughter is good, and the two often sew together to make new outfits for Vivian. Incidentally, the women of the Oscura family have apparently worn gothic lolita fashion for generations. She secretly supports her daughter’s efforts to improve the social standing of halflings. Toward the protagonist, she holds a certain kind of interest. The reason it is “a certain kind” is because she has never assassinated a ninja before, so she has a frightening interest in the protagonist’s neck. However, as she spends more time with him, she gradually begins to open up. Her hobbies are assassination, cooking and sewing, and maintaining her weapons. The things she dislikes are brightly colored clothes and bodies of water.
