Maina is a very timid girl with very dark hair that is tied into a ponytail from the back with a headband that has two bells on the side, with a flat screw head on the left and a screwdriver head on the right popping up. Maina is very timid, often very much so as she isn't as energetic or very assortative like her classmate, Mei Hatsume. Yet, she is also brave enough to get recognized to join the Heroes in the Final War against an army of Villains led by All For One.
