Oh dear no

is it horror?

Has some elements form it, like ghosts, mild gore and such. But as someone who does read horror the setting of the story doesn’t really work well enough to scare me. I never once considered this as horror until this commoner

thanks for the reply im not gonna read the manhwa then

I would say the horror and gore elements are pretty minimal (the gore is especially minimal imo. Nothing i don't see in shonen). It's more just a bit spooky at times since it has to do with exercising ghosts. But it's definitely *not* jump scare type stuff

Yes if you're not a fan of spooky things like mouths for eyes or weeping angels
