Chapter 17 out in raw, at last
Spoiler:
A couple of surprises. Aoi wasn't seeking out Hilda, but entirely the reverse. Aoi is thinking that Hilda has "miss-understood" something regarding Oga, initially wants to talk but realises quickly that that's useless as Hilda is going a bit demonic on us. They go at it hammer-and-tongs for a few pages, and Aoi seems to feel that Hilda might not be as strong as Oga, but then some other girls come running up to say that Oga has "half-killed" Nene and Chiaki. Aoi can't forgive Oga for this and has gone to the roof for a "final match" against Oga. Another cliff-hanger
I doubt Oga touched the girls. I bet it was long-hair - he seems like that type.
btw first volume (tankoubon) is coming out on the 3rd July.
