Synopsis
Ryuta and the other members of his science club go to a museum exhibit centered on Thomas Edison. There, they discover one of Edison's ideas that was never completed: a "spirit phone" meant to allow contact with the dead. Later that same day, they encounter a shaman who relays a message supposedly from Edison, giving Ryuta the full knowledge needed to build the device. Motivated by this information, Ryuta starts a spiritual journey to bring the spirit phone into existence.
