This animated film is based on The Slayers, and takes place before the events of the TV show, when Lina Inverse, the bandit-hunting sorceress roamed the galaxy looking for food and adventure with her fellow adventurer Naga. Using two tickets they recover from some bandits they've just defeated, Lina and Naga take a vacation on the exotic Mipross Island. Their leisure time is fleeting, and soon the two must use their swords and sorcery to fight off a band of villains.
