Haru, a 16-year-old prodigy, joins the elite Knight Order and is assigned to the "Black Hawk" 4th Cavalry Unit. His superior is Captain Karen, a 29-year-old single woman. Karen is known as the "Demon Knight Captain" or "Oni Knight Leader" due to her fierce and noble demeanor. However, Haru discovers a different side to her: she acts spoiled, invites him to her room, and shows special expressions only to him, revealing a cute and maidenly personality that she keeps hidden from others.
