The August issue of Square Enix 's Monthly Big Gangan magazine revealed on Wednesday that Chūgaku Akamatsu ( Aria the Scarlet Ammo ) and Mioko Ohnishi ( Battle Royale: Angels' Border ) will launch a new manga titled Fenrir in the magazine's next issue on August 25. Akamatsu is writing the story, while Ohnishi is drawing the art.

The magazine teases the manga as a historical fantasy epic, centering on a Mongolian boy and a beautiful girl, whose chance meeting will shake the whole of the continent.

Chūgaku Akamatsu 's Aria the Scarlet Ammo ( Hidan no Aria ) novels inspired an anime in 2011. Funimation streamed the anime as it aired, and released it on Blu-ray Disc and DVD in 2012. Kadokawa released the 28th volume of the novel series on May 25. Yoshino Koyoka has been drawing a manga adaptation of the novels in Kadokawa 's Monthly Comic Alive magazine since 2009, and Kadokawa published the 16th volume last September. Digital Manga Inc. previously released three volumes of the manga digitally.

The novels inspired Shogako Tachibana 's Aria the Scarlet Ammo Double A ( Hidan no Aria AA ) spinoff manga, which launched Young Gangan in 2010, and recently ended on May 18. The manga inspired a 12-episode television anime adaptation that premiered in October 2015. Funimation streamed the anime, and also released the anime on Blu-ray Disc and DVD in April 2017 with an English dub.

Ohnishi and Youhei Oguma drew the art for the Battle Royale: Angels' Border manga, with an original story by Koushun Takami , based on his dystopian novel Battle Royale . The manga launched in Akita Shoten 's Young Champion magazine in January 2011, and Akita Shoten published the one-volume manga in January 2012. Viz Media published the manga in June 2014.
