Case Closed manga volume 91 features story and art by Gosho Aoyama.

A man is killed in a cave-in, and his dying message points to a mythical monster—but Conan and Harley are sure it’s the work of a very human killer. Then the Kaito Kid sets his sights on a trick box containing the world’s largest moonstone, and it’s up to Conan to stop the master thief from hang gliding off into the night with it. And when Rachel and her friends go shopping for swimsuits, their bikini montage is interrupted by a murder in a dressing room!

Meanwhile, Conan’s classroom gets a new teacher. Ms. Wakasa seems nice, if oddly klutzy, but is there more to her than meets the eye?
