Now you're really pulling at straws. In terms of the story, Revy herself decided to wear tight shorts, and it isn't as if BL is a fan service series. Yes, you could argue that whoever created her thought of her arse more than her personality, but I doubt it going on how she acts like a dominatrex, often making Rock look like the bitch.
OT: I won auctions for the Starship Operators and Negima specials DVD. Why? Because the former was £10.77 and the latter is a R1 release of a series I'm collecting R1 releases of...for no real reason whatsoever.
