The Nanki Beach Mystery Tour (1)

Ran, Kogoro, and Conan go to Shirahama on a vacation they won from a shopping district lottery, and there meet a group of college students named Maki Shinjou, Tatsuhiko Yura, Madoka Mitsui, Kanako Miyahara, and Kouta Fuji. They are all in the same art club, but don't seem to get along well.
