That day ....
*This is a story about someone's memories in the past
She is a little girl who was born from a small town in Tokyo prefecture. Most of the people who live in the capital will certainly live a life full of pleasure, whatever is there is available, and there are many towering buildings in the city center. This little girl is always imaginative and interested in building a city where people can live happily and achieve what they want.
However, unfortunately... when he was in elementary school, his life was very bleak. After their parents gave birth to a younger brother who had more realistic things than him. For the next few years he was sidelined and earned the nickname of a useless child.
