I've yet to see any kind of ninja fanservice show which doesn't take the train straight for rapeytown. I think it's some sort of collective mental illness in anime writers that makes them go "femal ninjas = rape!". You have to tread lightly around certain fandoms' doujinshi for the same reason (although doujin writers seem to be able to turn *anything* into rape-fic, but that's another matter).To quote a wise man, "Huh." You'd think a fanservice-y ninja show would be along the lines of Battle Girls: Time Paradox, a fanservice-y samurai show. I guess... I guess you'd be wrong. Yikes.
I hate shit like this, and would be considerably happier were it not part of my hobby.
