>"I'll tell my father--" No you won't Erina, you're father doesn't give a shit about that stuff and only wants you as a tool. He'll throw you in a closet and not let you out until you beg for forgiveness and then you'll never see any of your friends again.
I'm team Megumi, but Erina is wins when it comes to hotness for me. Not a big fan of tsunderes, but Erina's tsundere side highlights her sexiness for me.
This anime needs so much more romance it's not funny! Perhaps the manga may have more... oh it probably does, the anime has a great ost but it is lacking in the romance department. Sekirei showed me just how much a manga and an anime can diverge, the manga was much more emotionally stimulating in my opinion as well, but I don't want to spoil anything.
