On Friday, a teaser promotional video for CTW's new browser game, Goblin Slayer: Endless Hunting, started streaming on the G123 official website. The main characters of the game are preview in the video.

The game was revealed by CTW on September 20. The game will be accessible anywhere. The first volume of Kumo Kagyu's dark fantasy novel series GoblinSlayer! was released by SBCreative in February 2016, and in May 2016, Ksuke Kurose (The IDOLM@STER Neue Green for Dearly Stars) began a running manga adaptation in Big Gangan. Kumo Kagyu's Goblin Slayer novels and Ksuke Kurose's manga adaptation have both been licensed by Yen Press. The books served as an inspiration for manga series and spin-off books.

The first season of the anime TV show with subtitles was streamed on Crunchyroll as it aired after making its Japanese debut in October 2018. The anime was also streamed by Funimation with an English dub.
