While I do have some issues with Kingdom Hearts --how dare they make Cid Highwind not swear or smoke! and Squall's name was just fine as it was!--- I can admit that I do like other things about it. I really enjoyed the whole Nobodies thing, Namine, Riku, and (sometimes) Sora. I like a lot of the Final Fantasy aspects of the game.
But mostly, I really like the Nobodies and Organization 13, for some reason.
I read a lot of Kingdom Hearts fan-fiction before even attempting to write my own. Mostly, it's given me a few pet peeves in fan-fictions but it's also given me some fresh ideas, some ideas to just say no to, and some very interesting authors to follow!
In A Green Dress (Roxas/Axel) Art student Axel Sinclair is desperate enough to take any job. His brother Reno talks him into cross-dressing to take the job of a lounge singer. Hilarity ensues when they are caught by one of the wait-staff and Axel must do whatever it takes to keep his secret. Technically, it's a cross-over with Final Fantasy VII and Final Fantasy VIII, but it's centered on Kingdom Hearts characters...
