The Caiman tribe lives peacefully and hunts in peace. One day, they were attacked by an alien race and the tribe's sacred relics were stolen. This relic has protected the tribe since the beginning, so it is clear that if the relic disappears, the tribe will perish. Additionally, the balance of nature is broken, causing chaos around the world. Accordingly, Caiman Chief Aluga sets out alone to find the relic. Wearing a mask that serves as his talisman, he sets out on an adventure to find the relic, equipped only with a sword, spear, and bow.
