Hello!

I'm looking for this manga which I used to read a couple of years ago,

I believe its genres are something like school, action, psychological, comedy, romance

And it's about a boy who gets accepted into a school which is on a floating island in the sky, only those who are able see the island are those who can get accepted into it. Also all the kids in the school have kanji characters written on them, which lets them use that word as a special ability, then they fight monsters until they graduate or die off.

if you know, please let me know

thanks 😎

It's Aphorism.
