Koushaku Reijou no Tashinami
Reminds me a little bit of the Princess of Death, but then not really. More of a 'feel' thing than any story similarity. It is also less a reincarnated, than it is thrown into a real life game world thing. But looks promising and might learn a bit about business and economy in the process.
Detarame Mousouryoku Opera
3 chaps - Somewhat whimsical, but really quite interesting with an underlying message about appreciating each other's talents and doing the best you can. The end seemed a little rushed, and it could easily continue where it left off. Honestly, it's a bit of a shame it doesn't.
Rock the Imperial Court
100+ ongoing (left off chap 77)
