Aki Nijou

Оригінальне ім’я: 二条秋

The school nurse. She is also the staff-advisor (sort of a "teacher overseer") of Maken-Ki. She was in the Maken-Ki of the school before it became an all-girl's school. She has absurdly huge breasts, possibly the largest of the cast, which attracts the attention of all male students and the envy of girls around her.
