“Getting a job is the grave of life.” Makoto Tanaka is a burned‑out employee of a black guild, a dungeon‑clearing company that works him to the bone. Day after day he descends into monster‑infested dungeons, recording his missions as private streams for company records. One morning, so sleep‑deprived he can barely think, he accidentally sets his stream to public while fighting an S‑rank Tyrant Dragon. Viewers across the country watch in awe as the exhausted salaryman kills the dragon with a single strike. The stream goes viral, and within hours Tanaka has a hundred million concurrent viewers. His boss, the greedy and abusive guild master Suda Akihiro, flies into a rage—but Tanaka simply quits on the spot. With the encouragement of his friend and former colleague Tsumugi Amatsuki, a skilled swordswoman known as the Ice Sword Princess, he decides to become a full‑time dungeon streamer. His new life as an independent content creator begins: he takes the handle “Samurai” and starts broadcasting his solo dungeon runs. On his first official stream he meets Yui Hoshino, a cheerful and popular female streamer who runs the channel “Yui Channel.” Together they face an unexpected irregular—a monster that should not appear in that part of the dungeon—and then an enormous dragon. Tanaka also reunites with his former disciple Rin Ayagawa, a earnest young woman who still looks up to him, and adopts a shape‑shifting EX‑rank monster cub named Riri, who becomes a loyal companion. As Tanaka’s subscriber count explodes, he must navigate the world of online streaming, deal with the fallout from his old guild, confront his former boss’s schemes, and eventually face even greater threats that emerge from the depths of the dungeons. The story follows his transformation from an exploited office drone into a free‑living, overpowered swordmaster who earns his living by doing what he does best—fighting monsters on camera.
