Thank you so much for the translation, Pikari-san! Ah, everything makes much more sense now.
If Fai's only missing half of his magic and one eye, he should be fine. Nothing to worry about. He was pretty powerful in the first place, and none of the other one-eyed people have been too disadvantaged by it. And if he ends up with a false eye like Subaru, Seishirou, et al., it should look just as pretty.
Really, I'm primarily worried about Syaoran right now.
