Goblin Slayer Season 1 contains episodes 1-12 of the anime directed by Takaharu Ozaki.

The Adventurer's Guild thinks goblin quests are low rank fodder; something for trainees to handle. But one silver ranked adventurer sees goblins for what they really are-monsters to be driven back to their caves-Goblin Slayer in tow.

Normally handling the dirty work alone, Goblin Slayer has a chance encounter with a porcelain ranked priestess who's eager to help him out. And with a recent increase in goblin attacks, he'll need all the help he can get.
