Kuniharu Ogino is a top police inspector. He previously partnered with police dog Hiroshi Inaba, forging strong mutual trust. After Hiroshi left to form his own detective agency, Ogino maintained their professional connection, frequently seeking the Inaba Detective Agency's help on cases involving organized crime, especially those concerning the Valentino mafia family. Ogino maintains a composed, professional demeanor during investigations and dangerous situations, handling them calmly. He wields standard police firearms proficiently, displaying quick reflexes and accuracy in confrontations. He possesses physical strength beyond ordinary human limits, demonstrated when he inadvertently pushed Hiroshi into pavement hard enough to embed him up to his neck. While typically stoic, he exhibits intense protectiveness over his family, particularly his daughter Azusa, reacting with extreme worry and decisive action if their safety is threatened. His family includes his wife, Wakaba Ogino, and daughter, Azusa. Wakaba has an exceptionally calm disposition and notable lack of danger awareness, traits that concern Ogino. He ensures their protection, such as placing them under Hiroshi's care when the Valentino family targeted them over a special key. He shows overt affection towards Azusa, described as a "dotting daddy," and evident care for Wakaba through efforts to include her in family activities and fulfill promises. Azusa reciprocates his affection, emulating him during play and demonstrating surprising physical capabilities like rapid construction and significant strength. Ogino's relationship with Hiroshi Inaba remains significant despite their professional separation. Ogino understands Hiroshi's abilities and temperament, being one of the few able to exert some control over him. Hiroshi holds specific admiration for Ogino's black hair, considering it exceptionally beautiful and preferable to white or silver hair. Their dynamic surfaces during investigations, though Hiroshi often initially resists collaboration. Conversely, Hiroshi's secretary, Yuuta Sasaki, harbors intense jealousy towards Ogino due to their past partnership and closeness. Yuuta repeatedly attempts to harm or hinder Ogino, who typically ignores these actions with minimal reaction, though he has referred to Yuuta as the "evil assistant". Specific incidents highlight Ogino's role and traits. During an early investigation into Don Valentino's counterfeiting operation, he personally sought the Inaba Detective Agency's help. Trapped under a refrigerator by the Valentino family, he partially freed himself, motivating the injured Hiroshi to continue the pursuit. His presence alone later caused the mafiosos to flee. His durability is frequently noted; he survives impacts like being struck by salt rocks or a refrigerator with little effect, though vulnerable to firearms or poison. He once remarked on his resilience after dynamite was used near him. Triggers related to his daughter provoke strong reactions, such as rage if Azusa gives Valentine's chocolate to someone else instead of him. An incident where Hiroshi burned someone for cutting Ogino's hair with cheap scissors underscores the peculiar importance of his hair within their dynamic.
