I'm thinking either blackout tattoos or he was one of the people that died and came back.
I think its those blackout tattoos, cuz his neck also got those stiches like tattoos
maybe blackout tattoos but i feel like it's something else since he like crawled out the ground but all the undead people have their faces like falling off
black out tattoos would make sense for the location of the tattoos but i also get the feeling he's from another world since he crawled out of the ground and doesn't look like a zombie? but then he also has a korean name and can read korean
Whatever he is, he's fine as truck
i just want to know why his arms are black but his fingernails and palms aren't, especially the fingernails
