When four worlds meet (Mha X The Disastrous life of saiki k X Hp X kotlc)

A crossover no-one wanted or needed but I'm writing anyway since I'm bored.

Characters from the disastrous life of saiki k, my hero academia and keeper of the lost cities end up in Hogwarts and learn about the magical world.

Again this is the crossover no-one wanted but I'm writing anyway.
