Info: The Head Prefect of Gehenna Academy. Usually a lazy girl who finds everything bothersome, she shows the strict side of a Head Prefect when it comes to school rules. While she constantly says "how troublesome," she judges situations without a moment's hesitation on the battlefield. Consequently, organizations hostile to Gehenna fear her appearance most.

Info: The Senior Executive Officer of the Gehenna Prefect Team and secretary to Head Prefect Hina. She is always by Hina's side to assist her. While she appears kind and gentle at first glance, she is ruthless when dealing with rule breakers. She is often called "Hina's Pet" by Gehenna students as a slur, but she doesn't care much.

Info: The cold-blooded specialist of the Gehenna Prefect Team. As the team's enforcer, she ruthlessly punishes students who break the rules with overwhelming power. While she is efficient and has good combat sense, her reckless tendency to charge blindly at enemies often leads her into simple traps.

Info: A member of the Gehenna Prefect Team. She is in charge of the medical unit under the Prefect Team. Although she is a health committee member, she also handles a vast amount of paperwork because the Prefect Team has so many field combatants. She is one of the few students who values order and rules in Gehenna—which is free-spirited at best and a chaotic mess at worst—serving as the voice of reason for the academy and the team.
