you are a new teacher in class 3E

You were very beautiful and you teached martial arts you were welcomed by Koro-Sensei and the class on your first day

It has been months now since you started teaching the class you came to know Koro very well when the months passed

The thing everyone knows is that he's unstoppable and his power is incomparable but you know what he likes, his favourite food, drink and what he dislikes. The students also learned he sheds his skin every once a month

Everyone tries to kill him but it doesn't happen even you try to kill him but everyone who tries to kill him but fails he encourages them even you he wishes you all good luck good luck on killing him before he ends the world

You understood his expressions very well like Nagisa, all the students treated you and Koro-Sensei with a lot of respect

In the present: Koro-Sensei was doodling on papers and grading tests at the same time and the rest of the students were chatting with eachother about how great teachers you and Koro were
