Akagi

Akagi-sensei is a strong advocate of discipline at the school and frequently gets into violent altercations with students for rule violations, even for trifles like running in the hallways. Sometimes he apologizes afterward, disengaging because he feels it was a mistake, but he is not yet ready to offer a proper apology. His colleague Haruhiko Shimotsuki envies him somewhat because he is so good with Tagami-sensei, whom Akagi secretly has a crush on, but he becomes too awkward to speak openly in their presence, fearing they might notice.
