Chapter 39 is out, closing out volume 8.
A lot of comedy in this chapter about Motoko's third father Tatsuya. The switchblade trick was nice though, definitely the truth unless you have a really good locking one. I laughed at the bathtub scene too, Motoko nearly killed herself.
I've thought this before, but I believe that Hibiki likes Kosukegawa the most. She was the first one who started to like him (while Motoko was busy having a crush on her therapist), and back when Fujiko went on a date with Kosukegawa (ending with the fight against baghead), Hibiki came out and remarked with much embarrassment to the others in HiFuMi that it was her turn for a date next time for sure. Aside from offering him Motoko's body early on, Hibiki just seems like she wants to spend time with Kosukegawa rather than fight. Fujiko is rather ambivalent about things most of the time, and Mikiri still prefers food over Kosukegawa.
If Hibiki is thinking about getting rid of Zero so that she can marry Kosukegawa, while Motoko is worried about Zero in general, maybe Hibiki likes him even more than Motoko does?
