It all begins in 1969 when a young boy named Kenji and his friends get together in their secret fort in a vacant lot and write "The Book of Prophecy." In their book, they write about a future where they fight against an evil organization trying to takeover the world and bring about doomsday. Years later in 1997, Kenji is the manager of a convenience store who has given up his dream of becoming a rock star and leads a simple life as he raises his sister’s baby girl Kanna after his sister suddenly disappears. Then one day, his boring life is turned upside down when his old classmate, Donkey dies mysteriously and then an entire family in his neighborhood disappears. At the same time, a mysterious cult being lead by a man only known as "Friend" emerges and begins to gain strong influence over society. A series of catastrophic events begin to occur mirroring the prophecies made up by the young Kenji and the greatest fear is the climax of The Book becoming a reality; December 31st, 2000, a terrifying giant virus-spreading robot will attack the entire city of Tokyo leading to the end of mankind. The only people who know about The Book are Kenji and his childhood friends. So who is Friend? One of their childhood friends or classmate? But who could it be? Will Kenji and his friends be able to stop Friend, save mankind, and live to see the 21st Century?
