In the year 2045, Earth is invaded by different worlds.
To defend against these invasions, Earth must conquer the dungeons connected to the other worlds.
As every country selects an explorer to undertake this responsibility, Japan thrusts an ordinary man, Gunma, into the front lines!
Terrified and overgeared, Gunma activates his "Pick Up Ears" and "Reconnaissance" skills, and encounters the strongest and most beautiful girl humanity has ever seen—but there's one catch: she's crazy and unstable.
She tosses Gunma around as they advance through the dungeons with unstoppable momentum.
Watch them mow down everything in their path in this groundbreaking dungeon fantasy!
