She is a member of the Oarai Girls' High School Tankery Team. She is the loader, gunner, and radio operator of the Turtle Team. She is always overbearing and condescending, but she is weak in a pinch and easily panics. She is a great believer in the former chairman, Kakutani, and was seen acting bravely to fill in for the absent chairman during the second time the school was in danger of closing down. She is in charge of the gunner, but her shooting skills are shockingly poor.
