@OofieBigMac it would certainly be interesting, and while I hope that doesn't happen since I want the series to continue, the fact that TBHK is so different from other manga of its type makes it very plausible, too.
But what I think what will happen- and I predicted this months ago- was that after Nene lost her ability to see youkai in exchange for a longer lifespan (I wasn't that off the mark about it, either), she would give it her all to see Hanako and interact with ghosts again- only to die shortly after, and remain together with Hanako in a sort of bittersweet ending (Dear My Living Dead, an earlier oneshot by Aida and Iro which is available in the first volume of TBHK, could possibly indicate this). I wasn't sure months earlier about what would be exchanged for the longer lifespan before, but now I know that it's Aoi, since she was sacrificed in order for Nene to live on the potential life Aoi could have lead.
I dunno, this is just what I think what'll happen.
Oh yeah, and btw has anyone noticed the absence of Kou? I'm surprised he hasn't gone running up to Yashiro asking where tf Mitsuba is.
