Thought you guys might enjoy learning about some of the youkai we've seen.
The Amikiri (net cutter): http://en.wikipedia.org/wiki/Image:SekienAmikiri.jpg (The Gantz one is much, much larger than normal)
Dorotabou (rice field mud-man): http://ja.wikipedia.org/wiki/%E6%B3%...94%B0%E5%9D%8A
Ohaguro Bettari (Black tooth): http://ja.wikipedia.org/wiki/%E3%81%...81%9F%E3%82%8A
(the "Real" Ohaguro Bettari didn't actually try to eat anyones eyes or brains, it just spooked you then stole your tea and ink to keep its teeth dyed).
And our favorite rapists two victims:
Rokurokubi (Stretching neck woman): http://en.wikipedia.org/wiki/Rokurokubi
Futakuchi-onna (two-mouthed woman): http://en.wikipedia.org/wiki/Futakuchi-onna
Still looking for that frog. It's adorable. Kinda reminds be of the frogs in the Choju Giga
