Good chapter. And I'm wondering if Yabuki will immediately let Matsuri revert back to female, or retire that plot element.
The thing is, Yabuki never really "used" it properly. Ninokuru blushed a few times, but otherwise, Matsuri didn't change at all, and he didn't have any interactions with anyone he wouldn't have had as a guy. Normally this plot element is interesting, but it wasn't so here.
Hmm... now that I think about it, the jutsu itself is probably something that converts Matsuri's own energy somehow, so I'm betting that once he gets some sleep and reverts, it'll automatically re-girl-ify him.
