I called that a gentle sociopath XDHe said he used that method in those dungeon so My guess is that He was completely dulled from the fear of death. Angel
that is probably it, his wife said so herself that he dies a lot of times to get to where he is
I like it Uruse better why did he have to leave I hate these manga Yamase is such pushover I don't like him give me back my Uruse
