anomaly: In the first level, as you are fighting your way off the estate just after you make your pact with the demon you come across a cliff with two waterfalls. Behind the left one is a secret, but behind the one on the right is the giggling manga girl having a shower from the original game.
Aye! There are many half nude, bathing, manga girls, in polygons, humming happily as they bathe! There are also more than one varieties of them! Near the end, where WANG sees two of them at the same time, yells something about: "Why are you in pixels and not in HD", or something along those lines... Heh heh.
