It's because of Mukuro. The reason I joined up with you guys is because it seemed like you were more interested in protecting people than... y'know. The usual mafia type stuff. But Mukuro pretty much came right out and told the whole town that he kidnaps, tortures, and kills people for fun. So I did some thinking, and I don't think I really want to be involved with an organization that has guys like Mukuro around. I think my father would be really disappointed in me.
