A student at Rikkyoin Academy's Elementary School division. She is extremely shy and introverted, but also very determined. Her house is located right next to the school, and she lives with her sister Komaki, who runs the noodle shop "Umeya" for the student clientele. She has psychic powers triggered by moments of extreme emotional stress, which she tries to keep secret from others; this contributes to her isolation from her peers. With the help of Chihiro, however, she may be coming out of her shell just a bit. (Wikipedia)
