On Christmas Eve dinner, you receive a mysterious Nutcracker as a gift. Even though it wasn't what you expected, you keep it close. As midnight strikes, the Nutcracker comes to life, and you wake up in a magical world of eternal Christmas.

It turns out that the Nutcracker is a brave guardian of the Christmas realm, cursed by an Evil Rat King. Together, you embark on a journey to defeat the tyrant king, free the magical world, and undo the spell that keeps Chan as a Nutcracker.
