This post is in reply to this fragment of discussion:
http://mangahelpers.com/forums/showt...72#post1403372 since it's best suited for this thread rather than a chapter-focused thread. (Come on people! If you want the mods to be more lenient then you guys need to be more post-responsible!

1, Already been answered; the curse was only effective for after it was applied. Except it was also a protective seal, as seen in the battle against Ashura when Kurogane was protected against a lot of injury from the enemy. Or maybe that's all it was after all, given his conversation with Tomoyo when he woke up in his world.
2, Ashura-ou wanted to be killed because he had been driven mad by his own power. He had known that someday he'd lose control, so he set Fai (Yuui) up to kill him someday. Rather than through hatred, he knew the kid had been through enough already, so he made it so it'd happen on its own once he surpassed Fai in power. That way his killing rampages could be stopped.
So, THAT curse was supposed to activate when he met someone more powerful than him in magic (Ashura the intended target), but since Fai was travelling and Sakura arranged it, he took it out on her instead. But also, the other curse was that if someone other than Fai killed Ashura, that Celes (his world) would collapse. Hence the big implosion when the battle was over. Both curses were gone after these activations.

4, Answered; it'd be hard to explain without spoiling xxxHolic. Highly recommend reading that story as well, it's excellent. Manga is more recommended than the anime, since the anime doesn't cross over into Tsubasa much at all by comparison.
5-6, Answered.
7, You did a good job yourself of figuring out what's what about the feathers in your post after that. They're still certainly significant; they were putting C!Sakura back together as a person. She wouldn't be who she became, had it not been for them, and her memories, being returned to her. The journey itself was also important for all the characters and their growth.
8, We'll seeeeeeee...
