Seekers ~Meikyuu Saikyou no Oji-san, Kami Haishinsha to Naru~シーカーズ～迷宮最強のおじさん、神配信者となる～; Seeker's: The Strongest Middle-Aged Man in the Labyrinth Becomes the Best Video Distributor.

"Seeker" is the number-1-ranked occupation which everyone wants to choose. Seekers make a living by running conquering-streams in the seven dungeons that exist in the whole world.
