Humans have created a Wall of Severance to separate themselves from the bears, who grew violent and attacked humans after a far-off planet known as Kumalia exploded many years ago, turning into a meteor shower that fell upon earth. Two bears, Ginko Yurishiro and Lulu Yurigasaki, sneak through the Wall of Severance and disguise themselves as humans, enrolling in Arashigaoka Academy and taking an interest in Kureha Tsubaki, a human girl who despises bears.

"I'm not saving the world. I just kill goblins."

Rumor has it that, in a certain guild in the middle of nowhere, there is an extraordinary man who has climbed all the way to the Silver rank just by killing goblins. At the same guild, a priestess who's just become a new adventurer has formed her first party... and the man who ends up rescuing that party when they get into trouble is none other than the Goblin Slayer.
