Sento's younger sister. She lives together with her brother and wants to do household chores, but Sento told her not to because he feels responsible for her. She cares for her brother and is frustrated that she is not allowed to help him, making her depressed and unhappy (and a prime target for Plug). (Source: Wikipedia)
