Hiruko

You reader of Poe no Ichizoku or Kazeki, you know bishōnen, you love bishōnen right?
Bishōnen are beautiful, they are gorgeous, they are frail, they are sensitive, they are androgynous, they are sexy…
But the one in that manga is also creepy, really creepy, and even more than that.

Hiruko is an horror one-shot manga from Ryōko Yamagishi, one of the core-members of the Forty-Niners and well known for being the mother of the modern yuri genre.
As it is a one-shot, I won't say more about its story than what I said above, because otherwise it will spoil everything.

Although I can say I really liked the building, the tension, and the uncertainty about what it is really happening. Also the ending of the manga might seem quite abrupt at first, even a little frustrating, but after some reflexions I do think that it was the best time for stopping it. One more page, and everything will probably be ruined by some revelation that'll reduce the tension, at best. At worse, it would overkill the manga.
