She usually handles all sorts of cases, but this time she is faced with a rather unusual request. The famous actress Kurata Sana is going to play in a new film as a detective. She wants to be able to impersonate her character as best as possible so she asks Shuri if she can stick around to learn a few things that real detectives do and how they act.
