In 2015, award-winning visual novel series Dies irae (music awards at the 2008 Bishoujo Game Awards and 2010 Moe Game Awards) blew the lid off of a crowdfunding campaign from creators Light that aimed to raise 30 million yen ($250,000) for an anime pilot. It ended up ultimately raising 300% of its goal. True to the plans announced last year, the anime is now confirmed for October's fall season (2015's plans had it in summer, but it became fall in 2016), and a new visual has been published along with the news.

J-List described the premise:
As the Soviet Union marches on Berlin in May of 1945, a secretive group of sorcerers and madmen gathers to perform a terrible ritual. They care nothing for the fate of the Reich. To them, the countless lives lost in the battle are the perfect sacrifice to fuel their spell. After the war, they vanish and are not heard from again, except in rumor. 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 wounds suffered in a vicious brawl with his best friend Shiro. As Christmas approaches, he tries to rebuild his life, clinging to what brilliance remains. 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?
