A petite girl whose catchphrase is "What a pain." As the head of the Prefect Team, she is considered one of the strongest in Kivotos. While she usually seems grumpy and is strict about rules, she is as delicate as anyone else and tends to shoulder burdens alone.

The executive officer of the Prefect Team who speaks her mind bluntly. She absolutely adores Hina. She has a strong will and once tried to beat Guest in a bet, but lost and ended up exposing herself to humiliation instead. She seems to have a habit of picking fights with Guest just to drag them into another wager.

The Prefect Team's vanguard who is straightforward in everything she does. While highly skilled, she often gets so focused on her opponent that she fails to notice traps at her feet. Ever since Guest licked her feet when they first met, she calls them a "pervert," but she seems to trust Guest deep down for their moments of sincerity.

One of the more sensible and conscientious students in Gehenna. Formerly of the Emergency Medicine Department, she handles medical treatment for the wounded on the front lines. She has poor eyesight and always wears glasses; apparently, everything is a blur without them.
