In the region centered around Ise-Shima, a phenomenon occurs where cultured pearls are experiencing near-total destruction. Pearl farmers evacuate the surviving pearls to the Japan Sea side, but during this time, a monster named Gamakujira appears.
Surprisingly, the monster begins eating pearls using its long tongue. Despite the attacks by the SSSP, the monster remains unaffected and continues to advance towards a major city where pearls are abundant!
