Mamimi is a 17 year old high school student. She waits for Naota when he’s finished with school. This causes Naota’s classmates to talk about him. Ninamori thinks that their relationship is inappropriate and called her a “child molester”. Mamimi was in a relationship with Naota’s brother (Tasuku) before he went to America to play baseball. Naota’s grandfather was never fond of Mamimi, especially when she was dating Tasuku. Nothing is known about Mamimi’s family. She is a smoker and goes around town starting fires.
