Mitsu attends Kijiyama North High School and plays as an attacking midfielder for the girls' football team. Mitsu is generally quite combative and has a hot temper, which leads to her frequently fighting with her opponents. While she also argues with her teammates regularly, she considers them as friends and is much more relaxed with them when not playing football. She has a big crush on Kunimitsu, and she acts much differently around him than anyone else, generally being shy and reserved. (Source: Mai Ball Wikia)
