Description
Mamoru Kagemori hails from a centuries-old ninja lineage sworn to protect the neighboring Konnyaku family. For four hundred years, the Kagemori family has guarded the Konnyakus, a duty defining Mamoru's life. He protects Yūna Konnyaku, the current descendant, a role he has filled since their kindergarten days.
To conceal his true identity and mission, Mamoru meticulously maintains a disguise. He presents himself publicly as an unremarkable, lazy teenager with perpetually messy hair and thick glasses, projecting deliberate apathy and clumsiness. This facade starkly contrasts his reality. When Yūna faces danger, he instantly dons his ninja suit, removes his glasses, and transforms into a supremely capable guardian. His exceptional ninja skills encompass advanced combat, stealth, and mastery of traditional weaponry. He has intercepted threats like a falling model airplane with a precisely thrown kunai and dismantled entire criminal organizations targeting Yūna, including yakuza groups. His swordsmanship is advanced enough to deflect bullets.
A formative childhood incident instilled a lasting fear of bears. He protected his relative, Yamame Hattori, from a bear attack. While successful in saving her, the encounter injured him and cemented this phobia.
He lives two sharply different lives. Outside protection duties, he exhibits laziness and low motivation, especially in mundane or academic tasks. Yet any threat to Yūna triggers an immediate shift to intense alertness, competence, and decisive action. Lifelong proximity grants him encyclopedic knowledge of Yūna's habits and daily life, though he remains unaware of her cherished nightly ritual: looking at a photograph of them together, symbolizing her hidden affection.
His relationships are complex. His deep, duty-bound bond with Yūna is central. Initially focused solely on his guardian role, subtle developments later hint his feelings might evolve beyond obligation. His actions also inadvertently attract romantic attention from multiple female characters, creating an unintended harem dynamic. This includes Airi Sawagashi, a wealthy classmate who outwardly discourages a relationship between Mamoru and Yūna while concealing her own feelings through aggressive teasing; Tsubaki Mapputatsu, a skilled swordswoman initially sent against him who later develops feelings after he helps her adjust to modern life; Yamame Hattori, his ninja cousin who initially disdains his disguised persona but regains respect after he rescues her; and Hotaru Kumogakure, a kunoichi from a rival clan who confesses love upon their first meeting and aids him despite clan conflicts, even using a kiss-based healing technique.
Mamoru generally remains oblivious or indifferent to these romantic advances, primarily fixated on protecting Yūna. His family enforces this duty strictly. His parents, Kengo and Sakurako Kagemori, are also skilled ninjas protecting Yūna's parents. They emphasize the continuation of both the protection duty and the Kagemori bloodline, sometimes employing extreme measures. His constant companion is Bluemaru, the Kagemori family's bull terrier, who appears ordinary but is a capable ninja dog assisting in missions.
His story extends beyond the initial 12-volume light novel series concluded in 2008. A sequel series, "Motto! Kage Kara Mamoru!", began serialization in July 2009, continuing his duties. The 12-episode anime adaptation concluded with a narrative reset: Yūna developed amnesia, forgetting both her confession of feelings and Mamoru's ninja identity, effectively reverting their relationship to its earlier state.
