Yen Press announced on Friday that it is launching the Goblin Slayer Side Story: Year One manga in English that day — which is also the same day it debuted in Japan. Artist Kento Eida is serializing this manga spinoff of Kumo Kagyu's Goblin Slayer! light novel series in Shueisha's Young Gangan magazine in Japan.

SB Creative published the first volume of the Goblin Slayer! dark fantasy novel series in February 2016, and the company published the sixth volume on September 14. Noboru Kannatsuki illustrates the novel series. The series centers on a man who desires to become an "adventurer," but insists on only killing goblins. The story begins with a female priest who has just joined a party, but quickly gets in trouble. She is saved by the man known as the "Goblin Slayer," a man who is ranked Gold (third highest) in his local guild in subduing goblins. In the story, he says, "I won't save the world, I just kill goblins." After hearing rumors about him, a female elf approaches him with a request.

Kōsuke Kurose (The [email protected] Neue Green for Dearly Stars) launched the main manga adaptation in May 2016.

Yen Press has licensed both the novels and Kurose's manga adaptation. The company published the third novel in print on August 22, and released the manga's 15th chapter digitally on August 25.
