you and the guardians, just for fun, are in something that's like a race of keyblade gliders, going through different worlds just to be in the race (like a normal KH game), right now all of you are in the first world in the race: Destiny islands

Sora: "This'll be fun, racing with the guardians, in the worlds, and winning a prize for that! Sounds amazing!"

Ventus: "Just don't cry when me, Terra and Aqua beat your team and get the prize."

Sora: "I should say that to you, sleepyhead."

Roxas: "Gosh, you two are idiots... My team will be the winner."
