The reason Kurogane chastised Fai for jumping from balcony to balcony is because Fai is also still dealing with his own wounds, too. Oh he's a worrier alright. :P That's all.

Ahaha, yeah...I did came up with an idea with an original world and even original characters for all main characters to land in that involved a world where the sun can no longer shine and it has to do with Sakura's feather of course. But there was no way I could be amazing and pull it off in a very short time like, um...everyone else so I had to be dull and stick to what CLAMP already provided. I still haven't read Reikah's story yet, but I am aware that hers blow mine way out of proportion a thousand times fold. xD

Thanks for reading and voting! :D
