Name: Hayato Matatagi. Gender: Male. Age: Around early elementary school age. He has two younger brothers, Yuta and Shun. While Yuta is a bit older, Shun is still a newborn baby. He lives in an old apartment building called Hinode-so. His father left the family and vanished, and his mother is hospitalized due to illness and is in no condition to work. He has been looking after his younger brothers all by himself. Hayato is often seen pressed against the window of a toy store, staring at something. It seems he really wants a toy called a "Byun-Kart." His mother told him, "If there's any money left over from the daily expenses, you can buy something you like," but he acts tough and declines, saying, "It's fine, it would just be a waste of money." Instead of using the leftover money for himself, he uses it to buy plenty of snacks for his younger brothers. Because of their poverty, he cannot afford the popular toys. Due to this, his classmates claim to be his friends to his face, but they exclude him behind his back.
