How is he scarred to hell like that when Yuri's abilities heal so completely outside of things like the eyes? I mean, I guess if he got them before meeting Yuri (...that's a shitload of scars for someone that just carried luggage and didn't do any fighting, however) it would make some sense, but even those old injuries might be healed, right?
I mean, this guy got his fucking face eviscerated by that huge bear monster like he was trying to french kiss a weed whacker. If injuries that would cause scars left scars regardless of Yuri's healing his entire face would just be claw marks.
