Once upon a time, Kasumi got kicked by Kamen Rider Kabuto off the Sears Tower. Then, mysteriously, "it" turned into a Keyblade, which a drunken, sore-in-the-*squeak* Sora started touching inappropriately. When "it" got stuck on the ground, Kasumi was pulled up by a old cripple named David. The cripple then stabbed Sephiroth in the back, while Tifa dropped a jar of Phoenix Downs on David. He stood up, screamed "Excelsior!" and got ran over by a chocobo shortly after.
The End.
