Movie
Description
Butt Detective possesses a humanoid body topped by a buttocks-shaped head, featuring eyes on each cheek and a vertical cleft functioning as both nose and mouth. This anatomical design is normalized within his world, carrying no scatological implications beyond its visual form. As a detective, he exhibits exceptional intellectual prowess with a stated IQ of 1,104, solving cases through rigorous logic, deductive reasoning, meticulous evidence analysis, and witness interrogations. He frequently employs visual puzzles—such as spotting discrepancies in images—to engage younger audiences in investigative thinking. Despite his typically composed and cerebral demeanor, he deploys a unique incapacitating technique: emitting potent flatulence from his facial cleft to subdue criminals like pig thieves or art forgers, seamlessly integrating this ability into his professional toolkit.

He balances intense focus with refined personal habits, unwinding after cases with hot baths, tea, and potato cakes, while displaying a recurring fondness for sweet potatoes. His resolutions are punctuated by the catchphrase "puputto fumutto kaiketsu" (roughly "a wind-breaking victory dance"). Professionally, he collaborates with Brown, a talking dog who acts as his primary investigative assistant. A pivotal backstory element involves his past partnership with Suisen, an art expert tied to the Metropolitan Museum of Art. This history resurfaces when she recruits him to expose a forgery ring implicating her mentor, Dr. Kinmoku, forcing him to navigate ethical tensions between loyalty and truth. His unwavering dedication is defined by his creed: "A detective is a person who carries out a job to the very end."

His adversaries include archetypal foes such as the Moriarty-inspired Shiriarty and organizations like the Phantom Thief Academy, led by Phantom Thief G. These confrontations test his resilience, sometimes causing physical injuries, yet consistently reaffirm his commitment to justice. His core traits, appearance, and abilities remain consistent throughout the franchise’s media.
