Nintendo Ds Otome Games?

not a whole lot unfortunately!

go to http://www.otomegames.com/games.shtml and there's a list of what's available on the DS in English but it's very small, and if you've got princess debut you've already got the best one...

it's much harder to get games like this on consol because on a computer ANYONE can make a game but on a console it has to be approved by the console owner and they have to print copies and so on, so they are much more picky about only doing things that they think will be BIG sellers. and you can't patch console games into english like you can with PC games either... so really you'll have better luck on the PC

eBay or Amazon, both are trustworthy if you know what you are doing. Or maybe just try an online game store like Gamestation.
