So, I have X fanfiction that I have waited 4 years to rec to people. Having now met the necessary characters, and knowing the most significant part of their backstory, I can now order you all to read the following:
Sakura and Snow- Like so many good things in (fanfic) life, it's a work in progress; she updates MAYBE once a year. But it's still worth it; this is one of the most gorgeous things I've ever read. This only deals briefly with X, since Seishirou/Subaru are pretty much exclusively the focus. However, it does occur slightly later in X than what we've watched up to. So SPOILERS for Tokyo Babylon, and some minor ones for X.
Leareth's Writings- I almost feel bad reccing S&S first, because it's hard to follow that. But Leareth's writings for Tokyo Babylon/X are also really good, and strike me as incredibly in character. "Unfortunately," she has a lot, so I can't give you reliable spoiler warnings. Assume SPOILERS for Tokyo Babylon, and hope she warns you for X spoilers. Although she follows the manga, so you can't be spoiled for the anime's end, at least. She links to some other good writers as well.
A Day in the Life- Warning: Plot. No explicit content. Tokyo Babylon only, so no X spoilers. In other words, you have no excuse to not read it.
Yami no Kopi-raito- Because it had to be pointed out.
And Sometimes, You're the Bug- xxxHolic, and... Tokyo Babylon? X? Tsubasa? Dunno. It's brilliant though.
-- Insaneidiot actually writes a lot of Tokyo Babylon/X stuff, and I must say that her crack is amusing, albeit spoiler-full.
Fleeting Fancies Recs- Or I could just make this site do my work for me. Not how I found most of my stuff, but the fact that she includes them indicates that at the very least, her recs will have proper spelling and grammar. She actually recs for lots of other series too, and generally sorts by pairing. Dive in.
And now, to thesis!
