The Despaircest sisters don't actually get much time on screen together but their relationship is pretty wonderfully terrible if you like that sort of thing and there's a very good Dangan Ronpa Let's Play (translated transcript plus screenshots) if you don't want to play the actual game.

Haha yeah the tags for Dragon Age etc are a often bit sad. And it can get convoluted eg I have written a few stories about my PC Martya Brosca, who is a Female Dwarf Commoner (or equivalently Female Brosca) both of which are a subset of Female Warden and of Dwarf Commoner/Brosca which are both subsets of Warden. Deciding how specific I should be with the tags can be tricky.

EDIT: Also thanks for putting that together! *browses* It's interesting that the one Dragon Age story of mine that got in is one I think of as fairly unpopular, but I guess it's just an unpopular pairing and the few people who bothered to read it must have liked it!
