Detective Conan. Vol. 2, 111

The child detectives and FBI Agent Camel cross paths. Individuals linked to the organization gather at the scene—including Rum, the Men in Black's number two, disguised as Kanenori Wakita. Meanwhile, as Ran, Sonoko, Sera, and Conan go for a snack at a hotel, Chihaya stumbles upon a murder at a hot spring, and the memory of those two comes back to her.
