None of these match up to Noisy Requiem: where a serial killer cuts a vaginal hole into a mannequin, and then stuffs the hole with the entrails of his victims so that it'll feel like the real thing. I can't even believe I just wrote that. And then you should see what he does to protect his "hole"....
I would recommend Survive Style 5+ for this list. If anything, the plot strand about the salaryman father who is permanently hypnotised into thinking he's a bird and how that concludes is bizarre (and surprisingly sweet) alone.
