In a world where stealth and protection are paramount, Mamoru Kageyama appears to be an unkempt young man with unruly hair and thick glasses. However, beneath this unassuming exterior lies a centuries-old legacy as a member of a prestigious ninja dynasty. For 400 years, Mamoru's family has secretly safeguarded their neighbors, the Konnyaku family, and his personal mission is to protect their young daughter, Yuna Konnyaku, whom he has sworn to defend since childhood. When Yuna finds herself in peril, Mamoru dons his ninja attire and transforms into a formidable warrior, ever ready to shield her from harm.
