Bayu, an eight years-old boy from Hening Village, finds a magical kris (a magical traditional asymmetrical dagger) in an old temple. Unexpectedly, the kris gives Bayu the abilities to transform into an armored tiger knight. At the same time, from its sheath, a giant rises into the ground, rampaging around the village, destroying everything and turns the villagers into stone figures. Along with his cousin, Rani, Bayu then meets Empu Tandra, a monkey who claims to be the previous owner of the kris. Empu then tells them the story of the kris, and how it was scattered into many parts when it was previously used to seal Asura the Titan. The party then goes to face Asura and his Shadow Soldiers.
