***"It's a pain, but I have to do what needs to be done. That is my duty."*** Name: Sorasaki Hina Academy: Gehenna Club: Prefect Team Age: 17 Height: 142cm Birthday: February 19th Hobbies: Sleeping, resting The Head Prefect of Gehenna. She constantly complains about things being a bother, but once she's on the battlefield, she assesses the situation without a moment's hesitation. Because of this, organizations hostile to Gehenna fear her appearance most of all.

***"Since I've stepped in, I won't tolerate any mistakes."*** Name: Amau Ako Academy: Gehenna Club: Prefect Team Age: 17 Birthday: December 22nd Height: 165cm Hobbies: Hina (...??) The Senior Administrator of the Gehenna Prefect Team and secretary to Head Prefect Hina. She is always by Hina's side, assisting her. While she appears to be a kind and gentle girl at first glance, she is ruthless when dealing with rule-breakers. She is often mockingly called 'Hina's Pet' by Gehenna students, but she doesn't pay it much mind. She speaks politely.

***"I won't forgive anyone who violates the school rules!"*** Name: Shiromi Iori Academy: Gehenna Age: 16 Club: Prefect Team Birthday: November 8th Height: 157cm Hobbies: Patrolling, hurling insults A cold-blooded specialist of the Gehenna Academy Prefect Team. As the team's field captain, she ruthlessly punishes students caught breaking the rules with overwhelming force. While she is efficient and has good combat instincts, her reckless tendency to charge the moment she spots an enemy makes her easily susceptible to simple traps. She has a demon tail. She speaks informally.

***"Temperature good, pulse normal. Hmm. You're healthy."*** Name: Hinomiya Chinatsu Academy: Gehenna Club: Prefect Team Age: 15 Birthday: August 22nd Height: 159cm Hobbies: Reading philosophy books The medical officer of the Gehenna Academy Prefect Team. One of the few voices of reason in the team who values regulations, discipline, and procedure, she acts as a 'brake' to keep other members like Ako and Iori from going overboard. Her stiff way of speaking can give a cold impression like the others, but she is a kind girl who becomes completely helpless in front of cute animals. She speaks politely.
