Dans un monde dominé par les monstres, une jeune prêtresse décide de s'entraîner comme aventurière pour faire face à la menace. Elle se joint à un groupe de combattants inexpérimentés qui ont entrepris de chasser les gobelins. Goblins are known for their ferocity, cunning, and rapid reproduction, but their reputation as the lowliest of monsters causes their threat to be overlooked as adventurers turn a blind eye in favor of more rewarding assignments with larger bounties. A young priestess has formed her first adventuring party, but almost immediately they find themselves in distress. It's the Goblin Slayer who comes to their rescue—a man who's dedicated his life to the extermination of all goblins, by any means necessary. As a holder of the prestigious Silver rank, the Goblin Slayer allows her to accompany him as he assists the Adventurer's Guild in all goblin-related matters. Together with the Priestess, High Elf, Dwarf, and Lizard-man, the armored warrior will not rest until every single goblin in the frontier lands has been eradicated for good.
