When the Vivolian army invades Floria, the Sprite Himawari and her childhood friend Tsubaki escape their homeland and settle in the town of Romton. For a while they live there peacefully. Then Ajisai, a fellow Sprite and friend of Himawari, is carried off by unknown strangers. Himawari and Tsubaki, who works as a detective, set out to save her, only to find the feared Vivolians blocking their path. This single-episode fantasy action special was made to promote the Flower 4 series in the Monster Strike game, but its story stands on its own.
