let's insert hilarity in it

Spoiler:

the bully gonna fall in love with the protagonist, get a blessing from Koro sensei and cheered up by the students

btw,
IMO Koro sensei not the one who kill the female teacher in 1st chapter, but I'm sure it's because of him near her, that she's killed. Koro being hunted by Earth so it's no wonder if unintended accident ensues. And may be Koro take out his anger on the moon because of her (hint: Koro mentioned that he was Earth born)
