Kodaka is a fucking racist offing the only two black people in the same episode
The only black person in the series is farmer dude, and he was absolutely pathetic. I guess being the most joke character of the lot, he was bound to be the type to get offed first less for the impact, but to inform the rules.
I guess Chisa could be the traitor. It could inform why her class succumbed to despair while she was still around. I felt that Hina's death was far more telegraphed than hers was, though, more so because I didn't necessarily expect anyone to get killed in episode 1 while Hina was waving death flags everywhere. Good target, though; puts more blame on Naegi.
The Werewolf in this scenario has it tough, since it started off essentially being 1 v 15. I guess the forbidden rules balance it out a bit more in their favor.
Edit: Yu Narukami is also a pick for the potential Werewolf, but I feel that'd be too obvious.
