@owyn too be fair, he doesn't necessarily like heavy armour, it's just something he needs cause heavy armour can cover him entirely to covers his skelly body so he won't be targeted as a monster. Now that he's openly killing humans, it no longer matters if he covers himself with armour or not especially since these guys are too weak to really damage or i think even hit him anyways
@owyn, i mean from a game persepective (like honestly this story is practically like SAO where he guy is in a world built like a game) its usually only heavy armour that has full longsleves, and the full helmat that covers the entire head and the neck. Heavy armour also is usually covering all joints leaving nothing open. I mean i guess some medium armour could do this but honestly it makes sense
