ISEKAI EXORCIST
C54/100Web serial by Dosei
After flunking his university entrance exam, Temaru Ryūta becomes a shut-in preparing for next year's attempt — until one summer day he is inexplicably transported to another world where people like him are expected to become Adventurers. To make matters worse, he is assigned the role of Exorcist, the most dangerous of all Adventurer roles. Ryūta reluctantly becomes the apprentice of a suspicious older Exorcist who proves to be a ruthless teacher. His new career is fraught with terrifying monsters drawn from real folktales and myths, uneasy pacts with supernatural entities, and corrupted Exorcists who have become part of the darkness they were meant to fight. A character-driven narrative with slow-burn progression, in-depth relationships, and mysteries the MC must learn to solve.
