The Grand Evil has been sealed in a cave behind an energized shield. After a thousand years, it begins to regain its former power and threatens to break free from the barrier. To prevent this disaster, the Elders of Fantasia decide to keep the radioactive energy contained and dispatch nymph warriors to locate and retrieve Ki‑Fighter cocoons hidden throughout the world. During their mission, the nymphs encounter TaeRang, a young Ki‑Fighter. TaeRang discovers that he possesses the power to defeat the Grand Evil, and he sets out on a quest to protect other vulnerable creatures and villages from the unjust evil, becoming a wise and brave hero in the process.
