Main cast

Main three characters

They love eachother and the pink one is gay for the blue one

It's a fucking great anime. The manga is splendid and the anime is exactly like it.

Here's the description for the manga:

Mairimashita! Iruma-kun is the story of Suzuki Iruma, who has been sold to the demon by his irresponsible parents in exchange for money. Surprisingly, next thing he knows, he is living with the demon and has been transferred into a school from Demon World. We invite you to follow Iruma-kun's extraordinary school life.

I highly recommend the manga because the anime only has two seasons and the Manga is so incredible and so so so gaaaaaaaaaaay.
