Raised deep in the mist‑shrouded forest by her wise master, a mighty‑strength five‑year‑old little girl sets off on a grand quest following four ancient keepsakes. She travels across brutal northern wastelands, fiery dragon mountains, the mysterious deep‑sea kingdom and storm‑wracked sky realm to track down her four powerful long‑lost elder brothers: wolf king, dragon king, merman king and eagle king. With burnt tree‑fruit cookies and sacred relics, she breaks through traps, sees through usurpers’ lies and overcomes deadly supernatural dangers. Though naive and childlike, her pure heart and extraordinary power win the respect of four mighty overlords. When she finally returns home, she finds her forest master has vanished, forcing the whole sibling group to unite and face a hidden dark crisis.
