Oshiri Tantei Movie 3: Sufure-tou no Himitsu

Butt Detective and his assistant Brown travel to Souffle Island, a place shaped by strong winds where people can ride the air and fly through the sky. The remarkable scenery does not make this a relaxing trip, however, because a difficult case and a secret tied to the island itself are waiting for them. Among powerful currents and unusual routes, Butt Detective collects small clues that others overlook while Brown faces an adventure requiring courage as much as careful thought. The closer they move toward the truth, the clearer it becomes that understanding how Souffle Island works is essential to solving the mystery that brought them there.
