So lessee... today we learned that...
1) Ichika's friend (Maho, iirc) is a straight chick and has a blond boyfriend, and they sneak off to make out when they have a chance. Bah. Not an all-yuri universe, then.
2) Hypnotic suggestion fails on male virgins. Perhaps on all virgins? Ah, but Khara hypnotized two schoolgirls... so either it's only male virgins who are protected, or those two schoolgirls were naughty kids, lol.
3) The end of the chapter suggests there are things going on we don't know about. Someone -- a vampire, one would guess -- hypnotized those two guys and made them carry Khara to Ichika's place. But it wasn't Aria, it wasn't Khara, it wasn't one of Aria's two cronies... then, who the hell did it? Did I miss something, or there's a mystery here?
