On the frontier, a guild member has achieved a feat that few can: he has risen to the rank of Silver Knight solely by tracking down and killing goblins. A young adventurer, the Priestess, has just begun her first adventure and soon finds herself facing a deadly threat. A man comes to her rescue, known as the Goblin Killer. He specializes in eliminating goblins by any means necessary, without any finesse. He teams up with the Priestess, to whom he likes to give a hard time, an always pleasant member of the guild and his childhood friend, the Vachère. Suddenly, an elf who has heard rumors about him comes to them with a request... This is the story of a man who only kills goblins, a man who aspires to be an adventurer.
