Halloween Town and Christmas City (a Yugioh story)

Five human children disappeared. It has been a month and twenty-two days after Halloween since the disappearance of these five children ... right before Christmas Eve by two days.
...
Yami, King of Darkness - aka, Pumpkin King- , is setting up already for next year's Halloween. It was December 23rd, with only a few more days until a new year arose for the humans. He had heard a rumor about five missing children, but dismissed the rumor in less than a second, thinking that children couldn't come to Halloween Town.
...
Yugi - the boy whose also known as Santa Claus and North, the man we love to have coming to our homes whilst we sleep on Christmas Eve - is rushing around, putting the final touches before Christmas Eve, when he rides his sleigh around the world in one night. Christmas Eve's tomorrow, Yugi thought, I have to finish everything and then have some of my friends searching for those missing kids so they get their presents.
