Oshiri Tantei 4th Season

With Brown at his side, the sharp-eyed Butt Detective continues solving the town’s strangest cases with calm deduction and impeccable manners. A supposed white monster on a snowy mountain, a vanished painter, suspicious packages, and a series of thefts keep his nose for mystery busy.

Brown also begins taking bigger steps toward becoming a detective himself, while the elusive Phantom Thief U once again turns ordinary investigations into elaborate games of wit. No matter how puzzling the clue, Butt Detective is determined to uncover the truth before the culprit slips away.
