Key of Time

Valkyrie still lives with Kazuto. One day a giant wand-like object called “Key of Time” appears before Valkyrie while she’s playing at the park. She starts helping others with the power of Key of Time and she keeps on using it without knowing its real power and purpose. Just as she helps Spot with Key of Time, it goes out of control all of a sudden. It turns into a chaos involving the entire town.
