Kingdom Hearts - As if being sorrounded by Disney Princesses wasn't enough.

Tifa's boobs look way bigger in FF7's FMVs, probably due to the 3D modelers getting some minor details a bit off when translating Nomura's art into 3D (remember this was one of Square's first big 3D projects). Granted she's still got ones that look about a D-cup or so in official art:

(the second art's from Dissidia 012)

Dude, it's Kingdom Hearts. Have you never seen jusy how close the male characters are to each other?

Sora, the good guy hero fighting his childhood friend that joined the dark side and then go on a search for him to bring him home?

And then there's Axel and Roxas. Two nobodies that learn how to feel with each other friendship.

If those stories aren't the perfect yaoi material to start a yaoi fandom then I don't know what is.
