Kage kara Mamoru!

To the casual observer, Mamoru Kagemori is the definition of unremarkable. He is an ordinary high school student who possesses no striking good looks, lacks any notable athletic prowess, and shows no signs of exceptional intelligence. Blending seamlessly into the background of his daily school life, he appears to be just another face in the crowd. However, this mundane exterior conceals a profound secret that has been passed down through generations. Beneath his average facade, Mamoru is the eldest son of a secretive ninja clan with a four-hundred-year history. For centuries, his family has upheld a singular, unwavering tradition: serving as the silent guardians of their neighbors, the Konnyaku family. Operating strictly from the shadows, they have dedicated their lives and formidable skills to ensuring the safety of those living next door. This ancient duty falls squarely on Mamoru’s shoulders, and his primary assignment is far from simple. He is tasked with protecting Yuna Konnyaku, the family's only daughter. Far from being a quiet ward who stays out of danger, Yuna is a natural-born troublemaker whose chaotic tendencies constantly attract unwanted complications. Now, Mamoru must navigate the challenges of his seemingly normal high school existence while covertly fulfilling his ancestral role, working tirelessly behind the scenes to keep the reckless Yuna safe from the endless chaos she inevitably invites.
