Hiroshi Inaba, engineered through human-wolf gene splicing, bears fluffy ears and a tail as remnants of his hybrid nature. His biological father, Sōmei Inaba—a former police dog hybrid—and younger brother Haruka, whose frail health contrasts his white hair, share this genetic legacy. Initially a police dog partnered with Inspector Kuniharu Ogino, Hiroshi resigned after Haruka’s disappearance to found a detective agency, determined to uncover his brother’s fate independently. Spiky red hair, brown eyes, rectangular glasses, and a leather collar define his appearance. His wolf transformation amplifies his stature, muscles, and crimson hair, with vertical pupils marking heightened senses and strength. Post a three-year gap, his hair elongates to mirror Haruka’s flowing style. Boisterous and stubborn, Hiroshi’s antics fuel comedic chaos, tempered only by Ogino’s authoritative rapport forged during their police tenure. Hiroshi’s signature skill involves analyzing hair to extract memories and traits, crucial for investigations. Consuming specific hair colors grants temporary abilities: black induces a despair aura, white triggers healing, blond generates electricity, and brown enables flight. Transitioning to wolf form requires Yuuta Sasaki, his secretary, to activate it via a precise martial arts strike. A protective yet oblivious brother complex drives Hiroshi’s pursuit of Haruka, unaware of Haruka’s ties to terrorist group NORA. Yuuta’s unrequited feelings for Hiroshi fuel rivalry with Ogino, while Kei Nozaki, the agency’s pragmatic anchor, manages finances and cat allergies amid Hiroshi’s eccentricities. Absurd clashes erupt with Don Valentino, a mafia-leading goat who devours currency. Hiroshi’s journey intertwines confronting Sōmei—framed for murder and NORA’s leader—with moral dilemmas in detective work. Evolving loyalties to Ogino, shifting alliances, and reluctant acceptance of Haruka’s autonomy chart his growth, threading personal reckoning with familial and ethical complexities.
