this chapter actually exceed my expectation. i thought author become "soft" since the kitsune in shimane didnt die, so i didnt believe the kitsune do this time will die either. and also contrary to popular guess they will enter berserk mode if one of them die, didnt happen. robara actually snaps from his psychopath due to shock.
but eh, like many people say, castration doesnt seem like a correct punishment since Robara only cares hinata and doesnt seem like he will do anything with any other female :/
