All bloodletters are that naked...Alright. Ass naked Bloodletter.
Did we REALLY needed to see this Relic?
To be honest as well, it's an M rated game. People explode into showers of fleshy bits and bloody mist. I don't see why violence is any less extreme than sexuality. I think in this case it's hard pressed to be called "extreme" in terms of sexuality anyway. Bloodletters are obviously male, and we're not exactly looking at genitalia. Females hold much more sexual prominence in the media, and typically butts aren't exactly the end all of extreme sexuality.
