Pretty sure he had blackout sleeve tattoos since in chap 5 you can see his palms and chest are the same skin color as his chest
Blackout Tattoo
Didn't he woke up from under a rubble?? I thought he died and came back to life or became a zombie but he was immune and the side effects or something is some of his body parts burnt like having frostbite or something??, cuz not gonna lie both of them is acting sus, like the Mc attacked him with full on killing intent w/ knife like he's having a PTSD and either trying to kill someone or in defense, and people low-key walking on eggshells around the big boss...? Or was that just me? （￣へ￣）
So like… is his whole body tattooed or… what am I looking at
