So I was exploring the table-top forum earlier, and apparently there's an anime style of D&D called Maid RPG. Obviously, it's focused on maids, but it's also placed in an anime setting with a typical harem idea in mind.
Yet just like D&D, it can be as completely random or serious as you want. The story can be similar to the gun-toting maids in Girls Bravo, who were all former military that could kick anyone's a** in a second. Or it could be focused on romance, kind of like the maids in Chobits. Really, it's up to the players.
Here's the website: http://www.maidrpg.com/index.shtml
I wonder if this could get started in our guild. Although I suck at story telling, so I could never be the DM. But as far as being a butler is concerned, I'd be in.
