Slayers

Young sorceress Lina Inverse and her dim-witted sidekick Gourry Gabriev travel through a somewhat medieval setting, doing good and fighting evil. Well, by "doing good and fighting evil" I mean "stealing from corrupt rich people and blowing things up". The stories in this volume are occasional tie-ins to the novels and short stories.

Lina Inverse, a wandering sorceress and bandit-killer, joins forces with roving swordsman Gourry Gabriev in what's supposed to be a quick union of convenience. *Note: This is the main Slayers manga, adapted from the Slayers novels vol.1-8. The fourth volume is adapted from the Slayers Return movie.*

Slayers Special is a novel series written by Hajime Kanzaka and illustrated by Rui Araizumi. Each volume consists of one-shot stories (sometimes, 2-chapters stories) about a pre-Slayers Lina Inverse and Naga the Serpent. (Source: Kanzaka Wiki).

Lina and Gourry are separated and Lina wakes up in a strange land that is outside of the mazoku barrier. There, she meets a boy named Lyos who is the Knight of Aqualord. Eventually Lina was reunited with Gourry, and Ameria appeared. They must search the God's power but the appeared Riskfalto, the Deep Sea Dolphin's general and all they will be involucred in a battle between gods and demons.

As a continuation of the Slayers Special novel series, each volume also consists of several one-shot stories (sometimes, 2-chapters stories) about a pre-Slayers Lina Inverse and Naga the Serpent. (Source: KanzakaDex)
