Oh yeah by the way, I started reading V3 yesterday.
I know that this game wants me to believe that Azula is the traitor, because she is by FAR the most suspicious, or one of the 2 girls of the tea party, but I think they are pulling my nipples here

I think that it's going to end up being Koharu, because she is incredible dumb, someone is manipulating her.
Either that or the fox faked her death because there's an event about her now and she was working for the villains all along
