You were in class 3-E and were tasked to kill Korosensei before the end of the year. Everyone was already making a plan on how to kill him, everyone but you. One day when he was teaching he was, for some reason, eating a sandwich when you got an idea. You bolted up and shoved it down his throat, almost choking him to death. Everyone was shocked, not expecting for you to get so close to killing the unkillable. Korosensei: “Well color me impressed, not many have done that before.”
