Eh.... this is tough. But after seeing the recent Oreimo episodes with.... that guy's name is and kuroneko, I really liked it. If I could multiples... I'd have gone with the tornadoes couple (and I still haven't seen the who anime and I know I should) and Suzaku and Euphemia from code geass... man I fucking hated what happened to her.
And I love SAO's light novel, so now that I'm starting to remember it from my head while typing this... but this this is an anime poll! And didn't enjoy the anime nearly as much as the light novel.
I love SAO and ToraDora. But I feel ToraDora's Taiga x Ryuji deserves to be the best couple. They connected on an emotional level and we got to see their romance develop from a love-hate friendship to a cute couple romance. Afterall, ToraDora is a romcom...
I'm going to have to choose an option not on the list :\ Sousuke and Chidori from Full Metal Panic! Especially in the light novels that take place after where TSR left off.
Black lagoon, Baccano, Cowboy Bebop, Patlabor, Ghost in the Shell, Irresponsible Captain Tylar, the original Dirty Pair, Mobile Suit Gundam 08th MS Team, Mobile Fighter G Gundam, Mazinkaiser, New Getter Robo, Mushi-shi, Kino's Journey, Samurai Champloo, Space Brothers, Chihaiyafuru, Skull Man, Sengoku Basara, Hellsing Ultimate, Iria:Zeirum the Animation, Osamu Tezuka's Phoenix, Naoki Urasawa's Monster,Golgo 13, Riding Bean, Gunsmith Cats Bubblegum Crisis (Both original and Tokyo 2040), AD Police Files and Mobile Suit Gundam Unicorn would all like to disagree with you, good sir
I voted for Ranma and Akane. It's not necessarily easy to like(on a platonic, let alone romantic level)someone who your drunk old pa's decide to just randomly pair you with for the hell of it(and expect you to keep that decision). The only leeway Ranma had was that he got to choose, sadly Akane didn't even have that lol.
But nevertheless, Ranma and Akane developed a bond that only those two could.
Old school classics:
In honor of Tofutehsurvivor: Char Aznable X Haman Karn. Hilariously, Char fought against Haman in both wars, yet in Char's Counterattack he decides to pretty much go through Haman's plans of having Humans inhabit space and become Spacenoids.
Reading Char's Deleted Affair is epic reading for any UC Gundam fan.
The fact that this and the Japanese poll go against Lesbianism is sexist discrimination I say!
I can name three unbelievable relationships that would lead a viewer to tears:
Aoi Nagisa X Shizuma Hanazono(Strawberry Panic).
Aaeru X Neviril(Simoun)
And finally, the queen of all Yuri relationships: Chikane X Himeko(Kannazuki no Miko)
Jeez, that's some stiff competition, but my number one couple will be Renton and Eureka. There's something about them that just fits so damn well. Renton's naivete and Eureka's slow but sure affection for him qualifies them as the #1 couple.
