20th Century Boys 2: The Last Hope(2009)

Part of the 20th Century Boys Collection

Kenji and his friends in the club created an amateur comic book that imagined an apocalyptic future in which strange illnesses and bands of armed insurgents threatened to destroy the world. A fanatical cult known as Friend found the book and they've made it their business to turn it into a reality, and now Kenji and his old friends have to infiltrate the cult and stop them before it's too late.
