Qu'est-ce qui se passe quand le monde de Beyblade disparaît dans les ténèbres - la veille de Noël - et que ses habitants sont éjectés aux quatre coins des mondes de KH ? Ben ça donne à peu près ça. Warning, pas vraiment de yaoi, mais quelques sous-entendus ... douteux. Et un bisou. C'est tout.

Gingka is a young energetic boy looking forward to exploring the world with his friends when a mysterious force causes him to gain a special weapon known as the Keyblade. Meanwhile, Masamune and Yu leave their castle to search for King Kenta and the chosen one who holds the Pegasus Keyblade, defeat the Organization, and save the world of Kingdom Hearts.

One day, Sora and Riku are visiting the Metal Fight Beyblade world. Sora gets invited to a party by Gingka, and wants Riku to go with him. Riku says "Fine." and goes to the party, where he meets a bunch of new friends. And one of his new friends reminds him of her...( Riku's POV/ Merry Christmas! )
