Seija Musou: Salaryman, Isekai de Ikinokoru Tame ni Ayumu Michi

Just before earning a promotion, a hardworking salaryman meets an untimely death and is reincarnated by a god into a magical world as a fifteen-year-old healer named Luciel. In this new world, healers are not well-liked, and Luciel feels threatened. Seeking safety, he joins the adventurers' guild, only to find the training far tougher than he expected, including being forced to drink a strange beverage called "Substance X" every day. This new life seems very different from what he imagined for a healer.

Determined to survive and thrive, Luciel faces daily challenges that test his endurance and spirit. His journey as a super-masochistic healer begins, filled with rigorous training and unexpected obstacles. Through perseverance and hard work, he aims to prove himself in this new world and find his place within it.
