## Description
Yukito doesn’t have a single relative after a great flood which claimed the lives of his parents when he was small. That was also when his younger sister went missing. One day, he happened to hear in the news that the past records pertaining to the disaster would be available to the public for the 15th anniversary of the event. He decided to return to his hometown of Kugumi village, holding on to the belief that if he checked those records he might be able to reunite with his long lost younger sister that he only faintly remembers.

## Characters
### Mima Yukito (美馬 雪人)
Yukito lost his parents and lost sight of his little sister because of a natural disaster. He was placed in an orphanage with [url=https://vndb.org/c14897]Chimari[/url], who also lost all her family.

As soon as he arrives in his hometown, Yukito realizes he has lost his wallet. He begins to look everywhere and is approached by a very pretty girl.

Yukito thanks her and she answers him that that she also loses things, then, they separate.

Yukito then finds a wallet on the ground and sees by the identity card that it is that of the girl. After some search time, he found her and he returned her wallet.

This is how he meets [url=https://vndb.org/c14894]Miyuki[/url] and learns that she has also returned to the city to find her older brother and begin their adventure.

### Meta (ミータ)
Meta ( also know as GNW-0021 Medical Treatment and nursing Automaton, MeTA ) is a robot with the appearence of a teenage girl. Initially built to help in the hospital, she was chosen to be the test subject of a large-scale experiment, the study of the relationship between humans and robots.

Meta is so advanced that it's impossible to guess that she's not human at first glance. Having an attractive face, advantageous curves and a skin of incomparable softness, [url=https://vndb.org/c69174]Yukito[/url] quickly falls "under her spell" and has a hard time believing that she is only a robot.

It's her personality that betrayed her. In order to be integrated by Humans, Meta must look like a human and behave and talk like them. To achieve this, she copies the "mimics" of her favorite characters to express her emotions ( Fufuri ~ ). She also has a great interest for all kinds of sports activities.

She is very popular at school, her closest friend seems to be [url=https://vndb.org/c14896]Ayaka[/url].

Since his arrival, she has taken a keen interest in [url=https://vndb.org/c69174]Yukito[/url][spoiler] ( she produces data that she doesn't understand when she is with him, in a first time )[/spoiler].

[spoiler]Her "mother" is [url=https://vndb.org/c69165]Rikka[/url].

Meta isn't a robot with a pre-programmed personality. She is a robot that "builds herself" with the experiences she lives, like a child growing up over the years.

She seems to understand very well the feelings that others experience and she often plays matchmakers. 

She knows a lot about sex but has never experienced it.

In her route, we learn that her life span is two years and that she is nearing the end of her second year of operation.[/spoiler]

### Mima Chimari (美馬 千毬)
Chimari is [url=https://vndb.org/c69174]Yukito[/url]'s adoptive sister. She is really adorable, cute and endearing, she is loved by all. She is a very ( extremely ) innocent girl, she often listens to the advice of her friend [url=https://vndb.org/c69162]Satori[/url] ( which is much less ) and does not understand the scope of some of her actions. She loves, enormously and innocently, [url=https://vndb.org/c69174]Yukito[/url] who became her only family.

She feels so lost when [url=https://vndb.org/c69174]Yukito[/url] returns to their hometown to find his biological younger sister that she decides to join him.

She is jealous of other girls who are too close to [url=https://vndb.org/c69174]Yukito[/url].

[spoiler]Because of her unhappy past, she has a hysterical fear of storms and regains her composure with [url=https://vndb.org/c69174]Yukito[/url] only.

In her route, she expresses her fear of losing [url=https://vndb.org/c69174]Yukito[/url], whom she considers as her only family to [url=https://vndb.org/c69162]Satori[/url], who will then help her to assert herself as a woman in front of [url=https://vndb.org/c69174]Yukito[/url] with wife-like bentos and gives her "sex education lessons". Chimari just understands that this is the ultimate form of loving someone and that the first time hurts, she does not know what sex is despite the ( fantasized ) lesson of her [url=https://vndb.org/c69162]friend[/url].

It is ultimately [url=https://vndb.org/c69174]Yukito[/url] who will hesitate to do the first step, knowing that his adopted little sister does not understand the scope of her actions, nor the scope of her words. His indecision hurts enormously Chimari, who does not understand why they do not do the "thing that [url=https://vndb.org/c69162]Satori-Chan[/url] explained ( with a nosebleeding )" if they love each other so much...[/spoiler]

She is a rather shy girl, especially with boys of her age, because she has only been to girls' schools. Having a nice face and a pleasing body, the boys often bother her and she is quite frightened of them and she sometimes calls them "[url=https://en.wikipedia.org/wiki/Man]Wolves[/url]".

Oddly, even though he often teases her, she is not frightened by [url=https://vndb.org/c69174]Yukito[/url], who has quickly become her friend she trusts.

She doesn't know how to lie, and seems messy given the state of her room ( or at all the messy stuff she probably hides in her closet when she receives [url=https://vndb.org/c69174]Yukito[/url] ). She always has good ideas, even if they seem a bit far-fetched.

[spoiler]In her route, she and [url=https://vndb.org/c69174]Yukito[/url] will participate in an event organized by the school, consisting of a three-legged race and a "runner's speech" at the end of the day. During the course, as they approach the finish line, Miyuki and [url=https://vndb.org/c69174]Yukito[/url] fall violently on the ground and roll their ankles. Not wanting to give up, [url=https://vndb.org/c69174]Yukito[/url] will then carry Miyuki to the finish line and arrive first. Some time later, it is their turn to go on stage and make their speech and it's Miyuki who speaks. Then she tells her story, her search for her brother, her arrival in the city, her meeting with [url=https://vndb.org/c69174]Yukito[/url]... Braving her shyness, she then turns to him and confesses her feelings and asks him to go out with her, that he agrees in front of the whole school.

Some time later, she learns who her [url=https://vndb.org/c69174]brother[/url] is, learns her true name, Miyuki ( 美幸 ) and learns she has [url=https://vndb.org/c14898]another sibling[/url].[/spoiler]

She is a bit violent with the peoples she cares. She seems very close to [url=https://vndb.org/c14895]Meta[/url].

[spoiler]In her route, she ran away from her home because she has a serious dispute with her [url=https://vndb.org/c69164]brother[/url]. Because she has no roof for sleep, she is collected by [url=https://vndb.org/c69174]Yukito[/url].

Then, they start to share the room in secret because Ayaka is not an official dorm resident and the dormitory forbids two people of different sexes from living in the same room ( for ethical reasons ).
