ボクのヒミツたいけん

The protagonist of the story and Yumi's nephew. He refers to himself using "boku".

His father is working abroad and his mother is taking care of her father, so he is left in the care of Yumi and her daughter. He is an only child.

He is mild-mannered and shy and unware that he looks pretty. He does whatever the girls tell him to do resulting in the creation of a "secret game"

While shy he is not an introvert. He is intelligent, likes games and has friends. He's not particularly good at sports.

He's interested in the opposite sex but too shy to do anything about it.  His embarrassment and single track mind regarding sex is found to be cute and is enough to attract girls.

Saeki Akira 佐伯 章

She is Narumi's younger sister. She is friends with Akira and Junpei's girlfriend. According to others she is "stupid and lecherous".

Kazuko is a cheerful and open-minded girl who can get along with anyone. However, it is said that she does not get along well with her older sister Narumi. She is characterized by her glasses and braided hair.

She looks like a quiet girl with glasses, but in fact, she is a leader among the four because of her curiosity and aggressiveness. Even her boyfriend, Junpei is completely under her control. She is a very active person, and is very active with the opposite sex which she inherited from her older sister.

She is one to speak her mind and makes her feelings and words known. She helps her friends when they are unable to express themselves out loud. She likes what she likes because she's straightforward.

Nakajima Kazuko 中島 和子

Yumi's only daughter. She is a cousin to Akira. Her father passed away shortly after she was born and has lived alone with her mother ever since. She is strong and very affectionate.

She has a strong personality and is not very sociable. When he speaks with Kazuko and others, she usually does not speak aggressively, but only replies with a simple "ah-ha". Of course, she treats Akira in the same way. In a sense, she is a shy girl like Akira.

Like a girl of her age, she is interested in sex and the opposite sex (especially Akira), but she is reluctant to move forward on her own. Most of the time, she is encouraged by Kazuko. She complains but goes along with Kazuko's actions, and it seems to show it.

She likes Akira, however, she can't be honest with herself due to her personality so she sometimes speaks to him in a spiteful manner. She is jealous of Kazuko who is open and frank with Akira.

She works for a company, but it is unclear what it is. However, Akira has seen her go to work during the weekdays. She is usually dressed very casually. She is young and does not look like a mother.

She is kind to Akira because he looks just like her late husband when he was young. She is a little happy to have an adorable son in her daily life as a single mother. She provides all kinds of service to Akira.

Saeki Yumi 佐伯 由美

He is a boy who lives up to his nickname of "one-punch boy. He likes to go out and about, which is probably why he is so tanned when he takes off his clothes. He is a bit childish, but he also hangs out with Kazuko and the girls in Yuki's group.

His personality is cheerful and a bit short-tempered. He is the type of good-natured kid you would expect to find at least one in your class. He has a funny way of talking and acting, and Kazuko plays with him.

He is not that popular with girls. He has a tendency to be easily infatuated. He is very knowledgeable about sex for some reason. Kazuko think of him as "stupid and lecherous"

Nakajima Narumi 中島 成美

A teacher at the cram school.

She lives in the same apartment as Yumi and her daughter and runs a cram school. She seems to be good at teaching. Even Junpei's grades seem to have increased enough for him to get a school award.

She has long hair tied up in a ribbon and Lolita-style clothing. She has big breasts and long hair, and has a calm and gentle personality. In a different way from Akira, she has a character of not being able to say no. She enjoys making sweets.

She is the envy of all the boys at the school, not to mention Akira, because of her big breasts, which Kazuko and Yuki do not have.
