Also...
I fail to see that point too as they pretty much fail to fall into depravity (it's actually the opposite, with their love and devotion being one of the purest of the whole setting by far and all that jazz).The name Ochimusha doesn't need to refer to the origin but could be a play on the words "ochi" from "ochiru" which means "fallen" and "musha" which is a "martial person". So essentially Kenkou just named her a "fallen martial person" probably to imply that she's a samurai that has "fallen" into depravity and lust after becoming an undead.
The profile itself... Well, it's not bad, one of the most elaborated entries we've had recently and the art (like almost always) is simply stunning... But it still baffles me that naming choice.... It's not faithful to the figure he's trying to allude, it doesn't use the name to symbolize anything in particular nor it seems like he's trying to get a quick laugh of his limited fanbase (like he did with the poor eelmaid).
I guess he just needed a "cool Japanese sounding name" for an undead swordswoman name and it was pretty much the first thing it came to his head...^^U
