Akane Aoi, a first-year high school student and student council vice president at Kamome Academy, has shared an unbroken childhood bond with Aoi Akane since their early years in adjacent apartments. His existence revolves around safeguarding her, persisting through over 3,600 rejected romantic confessions. He meticulously molds his life to her preferences—acing academics, joining the student council—to earn her favor. During their junior high entrance ceremony, Aoi faced mortal peril from a supernatural force. To rescue her, Akane forged a pact with Kako, the Clock Keeper of the Past, gaining time-freezing powers in exchange for a six-year tenure as the Guardian of the Present. His role demands maintaining the school’s timeline alongside Mirai and Kako. Cloaked in an owl-like mask and wielding a pocket watch, he halts time thrice daily for five minutes within campus bounds. In human form, rectangular glasses enchanted by Teru Minamoto veil his spiritual energy, masking supernatural awareness while permitting normal life. Despite this, latent strength surfaces in emotional surges—shattering objects or fracturing walls. Reddish-brown hair and eyes frame his uniform, marked by a safety-pinned student council armband. Akane’s obsessive loyalty coexists with pragmatic efficiency. Cynical and sharp-tongued yet respected for academic prowess—topping 224 peers—he despises supernaturals for devaluing human life, a conviction rooted in nearly losing Aoi long ago. Chapter 69 unveils his recognition of Aoi’s masked insecurities and self-imposed solitude. Though he condemns her façade, he vows unwavering protection even as she yearns to flee societal chains, embracing her imperfections. His dual existence as Clock Keeper and human clashes during the Severance event, which severs supernatural ties but spares his humanity. While mediating between figures like Teru and Kou, Aoi remains his compass. Spin-offs like *Delinquent, Glasses, Love, and War* spotlight his trademark bat-wielding defiance against rivals and unflinching loyalty, slightly softened by rare emotional glimpses. Trivia traces his raspberry pie preference, math brilliance, and shelves of books starring "Aoi" characters. A supernatural insect’s abdominal wound, stitched with fabric from Aoi’s kannagi dress, etches their fateful bond.
