Tokyo Sousa Sensen - Inubou

"If a dog walks, he gets a stick." As the lines from Iroha Garuta go.
Detective Gondo's nickname is "Inu-bo" (Dog Stick) as he walks around investigating. Toto Bank was robbed by three robbers, but the main suspect, who was waiting in a car, shot and killed the three robbers and fled.
Inu-bo's investigation begins.
