From this moment on, you are all my hostages.
About
Juri and Guest are dating, a famous couple in the same class as Suzune Minakoshi and Ren Nakao. At Kaiho High School, Ibuki Hiiragi, the homeroom teacher of Class 3-A, gathers all 31 students and suddenly announces, "From this moment on, you are all my hostages." An explosion echoes through the school, destroying the hallway and leaving the panicked students trapped inside the classroom. Hiiragi issues a challenge to the students: they must find out why Reina Kageyama took her own life six months ago. "Think about the cause, and let the one who knows the truth step forward." Reina was a national star and an Olympic swimming prospect, but she became the target of intense bullying after a fake video of her doping was spread online. Hiiragi threatens the stunned students, stating he will take their lives one by one if they fail the challenge. Simultaneously, Hiiragi reports himself to the police to have the school surrounded and demands donations from the general public watching the incident as entertainment via the social media platform "Mind Voice." Though initially confused and defiant, the students of Class 3-A gradually learn to think for themselves and see the essence of things through Hiiragi's "lessons." Facing their own mistakes and futures, the class unites to uncover the truth behind the incident.

Ibuki Hiiragi (27) The art teacher who started at Kaiho High School two years ago. He took over as the homeroom teacher for Class 3-A after the previous teacher went on leave following Reina Kageyama's death six months ago. The students call him "Bukky" and treated him as a "weakling" because he was originally unremarkable, but after the hostage situation begins, his personality shifts to one that is cold yet full of intense passion. He possesses high physical ability, enough to throw students who attack him, and is proficient with weapons like guns. He is also skilled with electronics, setting up remote-controlled bombs, surveillance cameras, and infrared sensors throughout the school, and installing special windows to prevent anyone from seeing inside, obstructing both student escapes and police intrusion. While his actions seem psychopathic, he calmly analyzes his position in conversations with his accomplices, showing consideration for his students by saying, "I should be the only one who commits a crime." First person: I (polite/soft) or I (rough/casual) depending on the situation.
