Wanpaku Tanteidan aka Naughty Detective Club OP

A group of young boys (plus a token girl and her little brother, the obligatory brat) form a detective club, pooling their talents for brain, brawn, invention, and driving skills to solve crimes in Tokyo. Much to the consternation of police chief Nakamura, they often succeed where the professionals fail. The first show made by Tezuka s studio from a nonTezuka work, this series adapts the juvenile Boy Detectives Club stories of Ranpo Edogawa, a 19thcentury novelist better known today for his Poeinspired tales of horror and suspense, some of which were adapted for the Animated Classics of Japanese Literature.
