Jimmy Kudo. He used to be a stallion who loved mystery. After being fed the poison, he's now a colt who loves mysteries, with a new name of Conan Edogawa. Join Conan as he takes on the mysteries in Equestria, and for him to find out the mystery of Pinkie Pie's nature!

This is a crossover between My Little Pony and Case Closed. Mysteries are everywhere, but with a keen eye for details, one truth will prevail.

Oh, did I mention Pinkie is significant to the plot? That's kind of important.
