Holy shit, this hardcore-as-fuck shoujo manga handled brainwashing better than anything modern has. It's not, "Aren't we friends?! Snap out of it!" it's "My God, you're right, why did I even do that? It just seemed so...natural."
Man, it's great that Ango has finally overcome his inner demons and even Ryo is more humanised... but I have mixed feelings due to all the crap they pulled. And these two and Team Summer B bonding together is going to lead to interesting conflicts when they eventually meet up with the other teams. We'll see.
