Slayers Smash.

Lina Inverse, a young and powerful sorceress, travels the world with her rival Naga the Serpent. Before the events of the main series, the two encounter various monsters, bandits, and magical mishaps.

Each volume collects several short stories, often complete in one or two chapters. From treasure hunts gone wrong to confrontations with eccentric wizards, Lina and Naga's adventures blend comedy and chaos as they clash with each other and the dangers around them.
