I'm really anal about my MKR pairings. I don't know why.
Fuu/Ferio is my ultimate OTP. Has been since like November 2000. *blush* Yeah... I've been known for that for years. XD Probably will be forevah, and I do not mind one bit. :B Updating the shrine this past month kinda sent me crashing rather violently back into the fandom. I gotta stop getting Fuu/Ferio plot bunnies. It's unhealthy. :o
Fuu/Ferio used to be the most popular pairing a couple years ago, but with all the new blood coming into the fandom, it's changed to Clef/Umi, much to my dismay. I know everyone loves it, but I swear CLAMP was smoking something when they came up with it. I find it absolutely out-of-character in the anime, especially if the feelings are reciprocated. I tried really hard to see it but I cannot. I've read like... two Clemi fics where the interaction between them didn't make my OOC radar go red. I know... everyone disagrees with me. D:
I ship Umi/Ascot more out of it being the alternate than because the pairing makes me wibble, although when it's written really well (which is harder to do than one might think), it does make me smile. ^-^
I hate Hikaru/Lantis as a pairing because she deserves someone with an actual personality. Her feelings all stem from deep-rooted guilt, I say!!! I do like the Lantis/Hikaru/Eagle love triangle of sorts for plot-type reasons. People occasionally handle it SO well.
I like Hikaru/Zazu. I wouldn't wish it in canon, but as an AU or whatever? It amuses me so. Lantis, especially in the anime, makes me want to put him in a field full of puppies and kittens and butterflies playing while "It's a Wonderful World" plays in the background... just to see if the idiot will PRETEND to smile. Or maybe say something less emo and deep. Augh! Hikaru/Lantis my BUTT. XD;
The Caldina/Lafarga pairing came out of NOWHERE, but it works for me. Doesn't do anything for me, but works.
The whole Sierra plot is on crack, and while I find the Presea-in-love-with-Clef thing stupid, I find the Sierra one even more annoying. More than Clemi. ;)
And when I see Primera/Mokona fics, a part of me dies.
