The Strange Adventure of a Broke Mercenary (Light Novel) Vol. 3

Loren knows better than to share Lapis's excitement when she brings him a new quest. It sounds easy enough--proctoring students from an adventuring academy on their final exam--but he knows his partner. Lapis has an ulterior motive. Sure enough, she claims that one of her missing parts is hidden within the labyrinth the students are delving into. She'll stop at nothing to reclaim it, even if it means endangering their charges. Worse, something's gone wrong with the labyrinth, and Loren soon realizes that his students will be lucky to get a passing grade--and he'll be lucky to survive.
