Adult visual novel developer Age announced on its official website on Thursday that the serialized novel Schwarzesmarken has an anime in the works.

Hiroki Uchida wrote the novel's scenario and CARNELIAN designed the characters and provided illustrations. Age's Hirohiko Yoshida is credited as the original creator. The novel ran for 41 chapters from 2011 to 2014 and was compiled into seven volumes. It was succeeded by the Schwarzesmarken Requiem light novel series by the same author and artist.

The novel's story focuses on the 666th in 1983, 18 years before the events of the earlier serialized novel Muv-Luv Alternative: Total Eclipse. Both novels are spinoffs of Age's 2006 visual novel software Muv-Luv Alternative.

The novels have two upcoming games, tentatively titled Schwarzesmarken Kōketsu no Monshō (Crest of Red Blood) and Schwarzesmarken Junkyōsha-tachi (Martyrs). The former is slated for this fall and the latter is slated for winter. Age also announced that a new side story titled Sekiei no Bernhard will begin in the August issue of Kadokawa's Tech Gian magazine next month.

The Muv-Luv Alternative: Total Eclipse anime premiered in Japan in 2012 from Ixtl and Satelight. Crunchyroll streamed the series as it aired, and Sentai Filmworks released the series on home video.

Update: The fall release window is for the game, not the anime. Thanks, jirg1901.
