In a world stalked by great beasts and frightening monsters, a more common creature is often overlooked: the goblin. While not as outright threatening as some of the larger nightmares out there, goblins are capable of grotesque feats of brutality in their own rights, often joining together in large bands and spreading destruction.

Enter the justly titled Goblin Slayer, whose sole mission in life is to wreak havoc on goblins, murdering as many of them as he possibly can. Utilizing the realm's reigning mission system for adventurers, Goblin Slayer makes sure to accept any and all goblin-related missions.

One of these quests brings him into contact with a young Priestess, who he rescues from an assault at the hands of a particularly nasty group of goblins who have raped and slaughtered her entire party. Although initially averse to human connection, Goblin Slayer begrudgingly finds himself developing an attachment to Priestess and the other party members that they gain along the way. Often tugged into massive adventures that pull him away from his goblin-murdering comfort zone, Goblin Slayer works to keep his party safe from harm and gradually overcomes the childhood trauma that crafted him into the killing machine he has become.
