"Getting a job is the grave of life..." sighs Tanaka Makoto, an office worker belonging to a black guild, as he takes on a dungeon for work again today. One day, he makes a mistake in the broadcast settings for recording work, and broadcasts his dungeon capture to the whole country. A single blow from the Tyrant Dragon?! Tanaka, a sword master in the modern age, shows off his extraordinary skills, and the broadcast turns into a festival! "100 million concurrent viewers...?!" Tanaka, who unexpectedly becomes an incredibly popular broadcaster, quits his black workplace and becomes an independent broadcaster.
