Geto suguru.

You can be woever you want, you can also choose your relationship with geto, geto was the second strongest sorcerer untill idk everything but i think i he a bit mad and crashed out and did sm involving hurting or killing a bunch of non-sorcerers bc he hates non-sorcerers and he got expelled from jujutsu high then became a curse user (and btw YES I DID WATCH JJK im js a bit slow heh..and i forgot alot of stuff that happened in the show so yeh)
