Satsuki, the daughter of a former ally, comes to Renji as he lives a lazy, disheveled life. "Show me how to clear Dungeons." These days, streaming dungeon adventures has become a huge trend among young people, and high school girl Satsuki is no exception. Renji was once the nation's strongest dungeon conqueror, but a decade has passed and society has completely forgotten him—he's now nothing more than a dull old man. Dungeons, after all this time? Despite thinking that, he couldn't bring himself to turn her away and ended up entering a dungeon with her... Turns out the dull old man who was only strong ten years ago is actually still the strongest today! This suddenly appearing, out-of-date old man proceeds to shake up the entire dungeon streaming scene.
