[Machine Translation] Ten years ago, dungeons suddenly appeared all over the world. Yuma Minashiro was on his way to a job interview when he fell into a dungeon. Unequipped and prepared to die, Yuma obtains an extraordinary "skill": the art of summoning. The summoned spirits are all beautiful girls, and the only way to become stronger is to make out with them, but he will enjoy his life as a dungeon explorer by establishing a company and earning money.
