An enthusiastic 28-year-old detective Yasunaga is assigned to work with a notoriously geeky 43-year-old rookie, Totori. Totori became a detective because of a secret "motivation," despite his previous outstanding career as an animal ecologist. Together with Yasunaga, the unusual rookie detective uses logical thinking and experiments to solve seemingly perfect crimes.<br />
<br />
Detective Totori and the Perfect Crimes uses a reverse format where the crime scene is presented at the start of each episode. This entertaining human crime drama, created by a talented young Japanese scriptwriter is masterfully filled with cunning suspects and witty conversation.
