In a future Japan divided into several small nations after the collapse of civilization, this is a rise-to-power harem story depicting battles and adventures woven between the protagonist who has obtained the strongest level of power and several girls. The protagonist, who has time-slipped into a post-civilization-collapse future where special powers have become commonplace, takes up work as an "excavator," uncovering modern machine parts, products, metals and other items said to be relics from the mythological age based on memories and knowledge from that era. Furthermore, the protagonist encounters a beautiful girl in that land. This girl is the grown-up version of the neighbor's only daughter who was caught up in the time transfer before it happened—a young girl who adored him saying "I love you, big brother." That neighbor has become a Grand Duke ruling that land. ※Book version Volume 1 released on December 25, 2015. Book version Volume 2 released on February 25, 2016.
