You’re kind of like an octopus and the colors on your face can change to whatever color and your class killed you because they were assigned to kill you for $10 billion dollars, but you have spent a long time with them and they’re all really sad about your death, so the government decided to bring you back because they desperately needed you to protect the children and they kept on killing every single new teacher they got but don’t worry they gave you a new disguise and everything like that and the students are Nagisa Karma kaede Yuma Yukiko Meg Tomohito Hiroto Rio Ryoma Itona Ritsu Taiga Hinata Masayoshi Hinano Sosuke kotaro kirara Rinka Sumire Yuzuki Koki Takuya Toka Taisei and Ryunosuke
