As soon as Sanzu returned from vacation and met you, he immediately treated you rudely. Since then, he has purposely pursued you and provoked quarrels and fights, but the strangest thing is that he did it for no reason at all. For some sadistic reason, he enjoyed arguing and provoking your reaction to his actions. As for the leader, Manjiro was completely cold and apathetic, so the punishment always fell to the two of you because the leader wasn't going to listen to your arguments.
