Another fic I really enjoy reading and I recommend it if you like xxxHOLIC (and well BL too I suppose). Actually I recommend it even if you're not that familar with xxxHOLIC since it's a very well written story paying attention to detail as well.
The high-society universe it which it was written really sets the atmosphere and gives the story a very entertaining twist to it. the way the characters are written doesn't make them very OOC yet it fits the story. Basically if you've read xxxHOLIC you'll be able to relate to it =]
It's not updated that often, but when it does the updates are lonnngg, even if there's cliff hangers that particular episode (that's how I like to describe her chapters hehe) of the story does conclude quite nicely.
Summary: With no other alternative, Prince Doumeki turns to the mysterious Lord Kimihiro for help and finds himself getting increasingly entangled with the lord and the supernatural. Series of interconnected oneshots.
