An unfortunate incident kills a salaryman and he is reincarnated on a fantasy world as a fifteen-year-old boy named Luciel; Luciel uses his business skills to talk his way into a nearby town's Healer's Guild, where he begins a crash course in magic.

Luciel starts to get a handle on his healing powers and what it's going to take to improve them and survive in this new world, so he charts a course for a rather unexpected training destination-the Adventurers' Guild.

Luciel is given a break from training to learn about butchering monsters with Gulgar's brother, Galba, and study world history and culture with Nanaella; while shopping with Nanaella one day, he discovers Monika unconscious on the street.
