Oshiri Tantei 9th Season

Butt Detective continues solving disappearances, robberies, and seemingly impossible mysteries alongside his loyal assistant Brown, following tiny clues until each case gives up its secret. This time, however, the investigations bring them into contact with new thieves connected to the mysterious Phantom Thief Academy.

As the criminals grow bolder and the danger eventually reaches Butt Detective and Brown themselves, the separate cases begin to form a larger confrontation with the academy. True to form, the detective meets every elaborate trick with calm observation and an instinct for trouble that rarely fails him.
