* Based on the erotic visual novel developed and published by Light.

As the Soviet Union marches on Berlin in May of 1945, a secretive group of sorcerers and madmen gathers to perform a terrible ritual. After the war, they vanish and are not heard from again, except in rumour. One day, it is whispered, they will return. And on that day, the world will end. Fear the demons in human form. Fear the Longinus Dreizehn Orden.

Flash forward to present-day Japan. Fujii Ren is released from the hospital after two months spent recovering from a vicious brawl with his best friend Yusa Shirou. As Christmas approaches, he tries to rebuild his life, but even that is soon threatened, for the knights of the LDO have returned and brought the apocalypse to his doorstep. Forced to wield the same unholy power as his foes, will Ren be able to protect what is dear to him from the inhuman might of the Longinus Dreizehn Orden?
