Lina and Gourry arrive in the seaside town of Acassi, where octopus tentacles are a local delicacy. After tasting the octopus meat, a curse forces anyone who eats it to speak only in Takogo, the language of octopi. Amelia, Zelgadiss, and Xelloss also appear, and Lina, Gourry, Ameria, and Zelgadiss become afflicted. The octopi, aided by a mazoku, plot to eliminate humans entirely. To save the town, the white sorceress Ruma must learn the cure to the curse from her long‑lost master.
