Day has never been known for her grace or luck. But one winter night goes overboard. Stranded in the middle of a snow forest, Day meets and promises six Pokémon that they will go on an adventure together. Five years later, Day hasn't forgotten her promise. Seems like the others haven't either. Together again, Day, Mud, Magic, Xmasbadluck, Emberfeather, Buggy Ninja and Skittygirl set out on an adventure to explore the world together. Criminals have a different plan for them. With Day's ability to partially understand Pokémon, they become subject to more than one criminal organization. And all they want to do is beat the Pokémon league and see the world. Is that so much?
