Jiko Dairinin Episode 4

A family search request comes to Toki and Hikaru, who run the Jiko Photo Studio. When they rush over, an elegant madam, Michie Takayanagi, welcomes them and tearfully pleads for them to find her missing beloved dog, Chacha. Pressured by Michie, the two agree but the only clue is a photograph taken by Chacha himself with his paw. Toki is left to attempt an unexpected dive into a dog. On this unprecedented mission, Toki runs around relying on the dog's vision and sense of smell, but hiding in the warehouse he arrives at is a man wanted for a hit-and-run.
