It has been about 30 years since dungeons suddenly appeared in the world. One morning, Daichi, a high school graduate and part-time worker, realizes that he has become an "explorer" with special abilities. As he gains power little by little through trial and error in a nearby dungeon, his dungeon life changes when he meets a female explorer named Kazeoto.
