A young boy named Cid Kagenou enjoys being a "shadowy power" in another world, and with the help of the girls he has made his subordinates - the Seven Shadows - he takes them on the side of justice (in all seriousness), and then the darkness in the world (maybe) will disappear. This is the start of a serious comedy about the Seven Shadows (and the main character) being the strongest, an overwhelming chuunibyou syndrome, and misunderstandings!?
