Otogi/Anzu - I don't know why, but they're my OTP <3
Atem (Yami)/Anzu - It's so cute....and canon.
Kaiba/Anzu - It's classic cold-hearted guy gets together with spirited warm girl hehe.
Yugi/Anzu - Even if he is like 2 ft. shorter, it's still cute.
Jounouchi/Mai - This is more canon than Yami/Anzu! Argh, they just keep teasing us with this. They're together, than apart, then together, then apart, then.....
Honda/Shizuka - Awwww, it's sweet. Honda seems like the perfect person for her.
Mokuba/Rebecca - Hehehe, puppy love. They're both geniuses so why not make a super smart short couple?
I like more, but these are my absolute favorites. Sorry I can't add much to the community, I'm so lazy.
See ya around.
