Lina Inverse and Gourry Gabriev stop in the seaside town of Acassi, where octopus tentacle is the local delicacy and a single meal leaves the eater able to speak only Takogo, the octopus tongue. Amelia and Zelgadis get caught by the same curse and Xelloss turns up to watch, while the white sorceress Ruma goes looking for her long-lost master and the cure he knows. The octopi, meanwhile, enlist a mazoku to be rid of humans for good. This manga retells the Slayers Premium film in five chapters.
