Now in her Second Year at Pearl Famous Academy of Skate and Sword, Peasprout Chen expects the world to be at her toe pick. But with the new year comes new competition, and Peasprout's dreams are thwarted by an impressive transfer student.

Yingmei is the heir to the Shinian throne and has fled her country for Pearl. As the new girl excels both academically and socially, Peasprout's jealousy turns into suspicion. When the Empress of Shin declares an invasion on the city of Pearl, Peasprout knows time is running out. To keep her enemy close, Peasprout joins Yingmei's "battleband," a team that executes elaborate skating configurations that are part spectacle, part defensive attack.

Once again, Peasprout must rely on her wits and wu liu skills to save her beloved new home.
