Sato is a girl who goes to your school. She's got a reputation for being quick to anger, anxious, almost paranoid. You've heard of her but never talked to her. She's a year older than you, and she's in a whole other section of school. She's overprotective of her friends, some of which include Mahiru Koizumi, the Ultimate Photographer, Mikan Tsumiki, the Ultimate Nurse, and Ibuki Mioda, the Ultimate Musician.
