Had to pick Kousaka Kyousuke × Kuroneko because its a cute couple and is on the list but if I got to pick any anime couple then I'd go with Tomoya x Kyou and if I can pick one from a eroge then Irina x Junichiro.
T-t-this is too complicated.
Can I just... THEY'RE ALL PERFECT
But obviously, Kirito x Asuna would win -- it's the most recent, and SAO is a unique anime, light novel, and manga. Because of its uniqueness (and the unreal things which happens in SAO), compared to other "simpler" and more "normal" works, it's a must-pick. But this is just my opinion. I love them, and I love SAO, so don't think otherwise.
It'd be awesome if FAKKU can have a poll for each anime or manga, so we can decide on a "top pairing", instead of a lot of pairings altogether.
I will vote for Sawako Kuronuma x Shota Kazehaya from Kimi ni Todoke.
But my top list of anime couple's is this:
Nr.1 Victorique de Blois x Kazuya Kujou from Gosick.
Nr.2 Louise Françoise Le Blanc de La Vallière x Saito Hiraga from Zero no Tsukaima.
Nr.3 Emma x William Jones from Emma: A Victorian Romance.
Nr.4 Holo x Kraft Lawrence from Spice and Wolf.
Nr.5 Nagisa Aoi x Shizuma Hanazono from Strawberry Panic.
Nr.6 Sawako Kuronuma x Shota Kazehaya from Kimi ni Todoke.
Nr.7 Aisaka Taiga x Ryuuji Takasu from Toradora.
Nr.8 Asuna Yuuki x Kazuto Kirigaya (Kirito) from Sword art Online.
The list will go on forever if I don't stop somewhere so this will do for now.
