Eien no Hou

Ryuta and his science-club friends learn that Thomas Edison once imagined a device capable of communicating with the dead. After a shaman delivers a message attributed to Edison, knowledge suddenly enters Ryuta's mind and allows him to construct the long-theorized spirit phone.

Activating it opens a path beyond the physical world, drawing the friends through realms shaped by the lives and beliefs of the departed. Their scientific curiosity becomes a spiritual journey as they search for answers about death, judgment, and the fate of the human soul.
