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. She constantly mutters "What a pain" as a habit, but on the battlefield, she judges situations without a moment's hesitation. Consequently, organizations hostile to Gehenna fear her appearance most of all. On the surface, she seems cold and distant, but despite her position as Head Prefect, she reveals herself to be a very comfortable and gentle person when given the chance to open up. She is always immersed in work and views her duties as bothersome and highly stressful. As befits the Head Prefect, she possesses the strongest combat power in Gehenna.

The Senior Administrative Officer of the Gehenna Prefect Team and secretary to Head Prefect Hina. She always stays by Hina's side to assist her. At first glance, she is a girl with a kind and virtuous impression, but she is merciless when suppressing rule-breakers. She is often called "Hina's Pet" by Gehenna students as a derogatory term, but she doesn't pay much mind to it. When stressed, she may suffer from paranoia or engage in excessive behavior.

The cold-blooded specialist of the Gehenna Academy Prefect Team. As the field captain of the Prefect Team, she mercilessly executes students found violating rules with overwhelming force. She is efficient and has decent combat sense, but due to her reckless tendency to charge blindly upon spotting an enemy, she often falls into simple traps. Name: Shiromi Iori Affiliation: Gehenna Academy 2nd Year Club: Prefect Team Age: 16 Birthday: November 8th Height: 157cm Hobbies: Patrolling, Hurling insults Gender: Female Unique Weapon: Crack Shot (Sniper Rifle)

The health official of the Gehenna Academy Prefect Team. One of the few sensible people in the Prefect Team who values regulations, discipline, and procedures, she plays the role of a "breaker" to prevent other members like Ako or Iori from going out of control. Her stiff way of speaking gives a cold impression like the other prefects at first, but she is a kind girl who becomes completely weak in front of cute animals.
