@Hounder
didn't he have ~3 points worth of shame about leaving his family behind and not visiting or anything since the cult arc? since that's the limit of his shame he can't lose, but technically it does mean he has SOME shame, small as it is...and it doesn't guarantee he'll actually be able to make everyone else lose too, which is his main goal right now...in spite of knowing it'll be some sort of evil existence or an outright demon, I kinda feel sorry for whatever took over the trials if it has to face him without anyone else to turn against him
I think he does have some shame with the guy that was always following him in the beginning; only Hai knows about the fact that Bai had a follower once upon a time so I'm thinking this arc might fall into him vs Hai.
