I haven't lost hope that the harem route is our final destination, since in this this very volume we had Kinue going down on Toudou, Shirashiro telling her she'll show her her panties (or lack thereof) whenever she wants, and of course the ghost harem.
I like the Hanei x Toudou scenes, but I miss Yomotsuka, and Kamisada hasn't had her turn yet, and I also want more scenes of that crazy Iwagaki, and that ghost girl Toudou kissed in the mountains.
