So I remember reading this book a couple years ago on Mangaowl, but the site got taken down and there was this one book that I remember and I'm trying to find it.
It started off with this guy who had long, shaggy hair, who was stuck in a cave and had scars all over him. What I remember most was his face being the worst, and he was extremely powerful, to the point that everyone was trying to get rid of him. Powerful in the way that he didn’t have to use weapons, he just used his hands and I think he did have some spell casting skills but I’m not sure. Then one day, he got his hair cut or he was revived with his hair cut, idk, but he didn't have any more scars on him and he was just as powerful as he was before the cave incident.
I also remember him having a friend who I think left him behind, but for a good cause, and they reunited or whatever and all was good. I also remember the main character being able to develop new levels by either beating people up or killing a creature made by the government or whatever.
And there was another instance where the main character and his reunited friend went to other houses and took down items found in the house, such as masks or a statue of a horse, and found out that they were "souvenirs" given to the owner of the house by the government, and those "souvenirs" had cameras or something lodged in them.
Idk if that's enough info but that's about as far as I got. 😭
