Case Closed, Vol. 7

Can Detective Conan crack the case...while trapped in a kid's body?

When ace high school detective Jimmy Kudo is fed a mysterious substance by a pair of nefarious men in black--poof! He is physically transformed into a first grader. Until Jimmy can find a cure for his miniature malady, he takes on the pseudonym Conan Edogawa and continues to solve all the cases that come his way.

On a remote island, a job request comes in from a pianist who's been dead for over 10 years. Can Conan solve the case of the cursed piano?

And later, a mysterious woman shows up claiming to be Jimmy's girlfriend. The only problem is, Conan's never seen her before in his life!
