Parting is not the end.
When Bumi and Xiaohu met again, their friendship evolved.
Holding the "Rainbow Prism" that can open thousands of worlds, they become guardians of time and space, traveling through fairy tales, animations and countless time and space on the verge of despair.
Their mission is to repair sorrow, convey hope, and protect the "smile" of all the world.
This is a journey that begins with "goodbye" and heads to "forever" - a journey that never ends.
