Season 1 of Goblin Slayer premiered on oktobris 7, 2018.

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.

Season 2 of Goblin Slayer premiered on oktobris 6, 2023.

Spring has arrived, and with it, a brand new year for the adventurers. The Goblin Slayer's party continues with their local exterminations of those little green pests while trying to also watch out for unsuspecting new questers who might not fully know what they're getting into. This includes an upstart young wizard who the Slayer takes it upon himself to try to talk some sense into. When that seems to fail in the face of the boy's ambitions, a different approach is arrived at: Have Priestess, the Goblin Slayer's erstwhile comrade, be the one to take the new kid in and show him the ropes!
