Rijichou Hisho

The busty school secretary who is really in charge of the high school instead of the headmaster. She makes the final decisions of all matters related to the school and agreed with the plan to build up a tent for the haunted house event organized by Riku. She often interrupts the headmaster whenever he is talking, making him feel out of place around her. It can be said that she treats him as if he wasn't there.
