Akatsuki no Monument is the second Detective Conan game for Game Boy Advance and features scenario mode as well as various mini-games. The main game story kicks off with Conan, Ran and Kogorou on their way to ceremony of a newly built resort by the sea. Kogorou Mouri, as a renowned detective (thanks to Conan), was invited to the opening ceremony, while Conan and Ran are just tagging along. As they arrive, the owner of the luxury resort asks them to look into the rumors about the land where the mansion was built on. The rumor is known as the so called "village of suicides". Later that evening, as they check the buffet and meet many other invited guests, pleasantries are exchanged and small talks reveal little to nothing of interest... until, a body falls down on a sports car that was on the display in the lobby area. Coincidence, or is there really some truth to these rumors... Conan is taking up to find out the truth and discover the mystery behind this death as well as the rumors that are plaguing the area.
