A talking Beagle with brown-and-white fur sports a signature deerstalker hat, his canine form the result of an unexplained incident that transformed him from a celebrated human detective. Retaining full human intellect, razor-sharp observation skills, and mastery of investigative methods, he navigates mysteries with the same deductive prowess that once defined his human career. His speech, however, manifests only to individuals marked by innate curiosity or detective potential—a trait anchoring his partnership with a young, intuition-driven female detective.

Their collaboration thrives on complementary contrasts: his methodical analysis and decades of experience offset her unorthodox, instinctive approaches. Though mutual respect underpins their dynamic, their interactions oscillate between mentorship and playful rivalry, particularly during investigations. Fragmentary references to his human past hint at a career entangled with perilous cases, yet the precise catalyst for his transformation remains obscured. Subtle gestures and terse remarks occasionally betray an undercurrent of conflict regarding his canine existence, though his focus never wavers from solving cases or nurturing his partner’s growth.

Dry humor, steadfast patience, and sporadic exasperation define his demeanor, tempered by an unwavering loyalty to justice. He leverages canine advantages—heightened hearing, scent tracking—to bypass physical limitations, while maintaining the facade of a普通の犬 (ordinary dog) to outsiders. Over time, he grapples with the symbiosis of their partnership, gradually reconciling nostalgia for his human identity with his current role. The narrative remains silent on his pre-transformation relationships, familial ties, or ambitions beyond immediate cases, centering instead on the duo’s pursuit of truth through tangled webs of supernatural intrigue and human deception.
