*cries when the girls are killed while alone...*
one thing is to have someone to compete with, but his true rival grew some boobs and a maniac took the vacant place -_-
if he didn't care about people being killed he can play games, but he doesn't look like someone who would take tragedy without crying while shouting at the skies.
the guy who led them also is alive and kicking... what a smooth sweet manga. go over his house and bring some quake, you can all be happy and sing.
the enemy isn't the only crazy here, for me mc isn't right in the head either, acting like everything is only a game despite the life of the weak ones also being in the line.
