Foilshipping, Vampire Hunter AU. Yuma's oh-so-good vampire friend Shingetsu always needs someone to get a snack off of in the bathroom stalls, and it's always Yuma to no one's surprise since he's been keeping it a secret this whole time.

Rivalshipping (meant to be platonic but can be read as romantic). Post-canon, Judai comes back to see Manjoume for a night, and while Manjoume's been holding up just fine without his friend all this time he doesn't take the "leaving again" part very well.

Starshipping, 5DXAL Heartland AU. Judai's graduating soon, and he's been doing some thinking about his and Yusei's relationship, and what they're ?supposed? to do with it. (((featuring headcanons of aceprotags and yusei sometimes saying hilariously cheesy stuff)))

Aztecshipping/past Keyshipping. Post-Series, Michael and Yuma have a sleepover while adjusting to new lives of normalcy, and Michael discovers that Yuma maybe isn't as okay as he tries to come off. But when was that new? Other than Yuma's sudden interest in ESPer Robin, that is.
