One day, he accidentally broadcasts a video of himself effortlessly defeating an S-rank monster on the company's network, which goes viral, attracting 100 million viewers. Suddenly in the spotlight, Takahashi is berated by his guild's CEO, to which he responds by quitting. Now jobless, he becomes a freelance dungeon streamer, gaining fame and success, while the guild that expelled him begins to crumble.
