For nearly a millennium, demons have imposed a magical barrier that has impeded the people trapped within it from reaching the outside world. Now that it is broken, several kingdoms seek to explore the lands that were once beyond their grasp. To this end, they establish a peace delegation to make contact with the inhabitants of the new world.

Meanwhile, the young sorceress Lina Inverse receives a message from a mysterious woman named Filia ul Copt. When they meet, Filia expresses interest in hiring Lina and her friends, having heard of their great deeds, for a certain task that will take them to the outside realm. Despite that, Filia feels the need to put their strength to the test and pits them against a dragon in the middle of the city! After proving themselves, the sorceress and her fellow adventurers set off for the unexplored lands, where many adventures and a worrying prophecy await them.

Eredetileg "Slayers: Try".

千年前の降魔戦争以来、大陸を覆っていた結界がリナたちが、ヘルマスター・フィブリゾを倒したことにより、消滅し、外との行き来が可能になった。外の世界からやってきたフィリアから、滅びの神託による世界の危機を救って欲しいとの依頼を受け、リナたちの旅がまた、始まるのだった。

Après la mort d'Hellmaster Phibrizo, les barrières magiques entourant leur monde se sont effondrées. « L'autre monde », au-delà des mers, peut ainsi être exploré. C'est d'ailleurs là que se dérouleront les nouvelles aventures de Lina et ses amis. Mais ils se retrouvent très vite mêlés à la Prophétie du Chaos. Celle-ci annonce la fin du monde si on ne fait rien pour l'en empêcher.
