On Christmas Eve night, Sora is given a gift that magically transports them to Earth, giving the group the chance to travel to the North Pole by riding the legendary Polar Express. Riku is skeptical, however, given he has not believed in Santa Claus since he was a child. Suspicious, he decides to follow his friends and tag along. Will he ever find his Christmas spirit?

(could-be canon for 'The X-blade Wielder' universe) It's Christmas Eve, and the Polar Express is fulfilling its duty of carrying lucky children to the North Pole. However, this year it has four additional passengers- none other than Sora, Riku, Kairi, and Heavyn! While Heavyn is happily living her childhood dream, will the others manage to survive all of the hijinks that ensue?
