Ikasama Kouboh (Circle)

A two-part doujinshi. In the first half, we get a peek at the cast (including appearances by Luna, Amelia, and Zel) getting up to their usual antics before the final battle. Later, Luke reflects on how he met Millena, and Lina and Gourry say goodbye before setting out on their next journey. (Takes place largely after volume 15 of the novels. If you’re not at least familiar with the events that happen within, you might want to familiarize yourself.)

A series of short gags about the Slayers casts’ various experience with “firsts”. (First impressions, first spells, etc.)
