At the end of the 1990s, Kenji Endo is living an ordinary life when a series of strange events reminds him of the games he invented as a child with his friends. Back then, they created a secret symbol, an evil organization, and an apocalyptic scenario meant to be stopped by a group of heroes. Years later, a mysterious cult led by a man known as “Friend” appears to be recreating those ideas with disturbing accuracy. Kenji reunites with his former childhood companions to discover who is using their memories and why. Between conspiracies, political manipulation, terrorism, and secrets buried in their past, the group realizes that their childhood games may have become the blueprint for a real global catastrophe.
