My friends did the thing they usually do.
The cover art, aside from the logo, consist of three main layers: the character silhouette, decorative patterns, and a photo of a telecom tower. The combination of geometrically shaped holes on the patterns, shapes that are part of the patterns themselves, and some devious use of pallettes, has made the cover hard to read. It's easy to mistake some of the holes with the character silhouette.
Methinks she's going to be some sort of mix between several urban legends. I mean...
1) Her name is
Hanako, like the toilet spirit (At least according to the data rip).
2) Assuming those square things are paper, they could be
Aka Manto's red and blue paper.
3) She seems to have only one leg, which hints towards
Keshima Reiko (even though that one lost both her legs).
I wish this could explain what's up with her strange turban-with-a-handle, though (Gozu, maybe?).
So I'm gonna assume our newhu is either that or a Kyorinrin, like Malyszeq said (Who knows, maybe she's even both!).
