One of Takayuki's older works from 2003. Apparently he's been pretty weird for a long time, but I love his stuff nonetheless. Be warned, there is a lot of amputee content if you dislike that sort of thing.
According to mugi the artist is Kawai Takahiro and not Aoi Takayuki. Maybe someone who can read J can verify this? If this needs to be rerenamed post on the forums.
