Oshiri Tantei Movie 2: Tentoumushi Iseki no Nazo

Butt Detective receives a request from his father, Butt Dandy, and travels to the Ladybug Ruins, where a hidden treasure may hold the key to saving Tenten Village from a severe lack of rain. Dandy heads into the ruins first with a local child named Panten, only to become the target of two suspicious figures seeking the treasure for themselves. Then a warning arrives from Phantom Thief U, adding another player to the case. Butt Detective follows with Brown and encounters a chain of riddles and traps built into the ancient site. Saving the village and protecting the treasure will require both his precise deductions and the adventurous spirit he inherited from his father.
