Odd chapter to say the least, on one side I enjoyed seeing Erina's reaction, and i'm interested to see what Azami was talking about, but I really don't like the direction the manga is going in, it makes no sense the way those three were dismissed from the elite ten. Which again puts a giant question mark over the elite ten members voting for this new egime in the first place, thy are essentially handing over all the power they had to the head master, they are nothing more tan puppets now, if they don't agree with the new order they will be dismissed from their seat.
Going back to the reveal, while it was amusing and Azami's words did intrigue me, I'm not happy the reveal happened the way it did, it pretty much put a massive question mark over Erina and Souma's relationship now, no matter how they write it now, the question will remain if Erina's behaviour towards Souma is influenced by him being Jouchirou's son or not, it's a dumb idiotic move.
Really hate the direction this manga is taking, it's too similar to other battle manga's from the Weekly Jump, which makes you question if the story even belongs to the mangaka's anymore or if it's another manga being controlled by the editors who want to leave their stamp on the work. I hope I'm wrong, but if the manga continues the direction it's going in, it will lose allot of it's appeal, I can see myself dropping i, or just reading the chapters and not really caring for the content, like I've been doing with Bleach for years.
