Worse, it turns out the mastermind behind the attack is someone they know…

Several secret pasts are finally revealed this volume: The tragedy that led Principal Asano to develop his harsh—some would say brutal, sadistic and inhumane—pedagogical methods, the relationship that gives one 3-E student a personal motivation to assassinate her teacher, and even Koro Sensei’s origin story! Will the students be more or less motivated to assassinate their teacher after they know his former secret identity?
