Series is sequel to original light novel series that inspired 2010 TV anime

The 17th volume of Takaya Kagami 's Dai Densetsu no Yūsha no Densetsu (The Legend of the Great Legendary Heroes) novels revealed last October that Kagami will end the novel series with the 18th volume.

Dai Densetsu no Yūsha no Densetsu is the sequel to Kagami's original Densetsu no Yūsha no Densetsu ( The Legend of the Legendary Heroes ) light novel series. The original series ran for 11 volumes from 2002 to 2006, and Kagami released the first volume of Dai Densetsu no Yūsha no Densetsu in 2007.

Kagami also wrote the 11-volume short story collection series Toriaezu Densetsu no Yūsha no Densetsu from 2002 to 2007, and the eight-volume Shin Denyūden: Kakumei-hen - Ochita Kuroi Yūsha no Densetsu novel spinoffs from 2007 to 2013. Saori Toyota illustrates the novels.

The novels inspired a television anime adaptation covering the original novel series in 2010. Funimation licensed the series and streamed the series as it aired in Japan. The company also released the anime on Blu-ray Disc and DVD in 2012. Funimation describes the anime:

Ryner is not your typical soldier. Cursed with a mysterious, deadly power - the Alpha Stigma - he has been called a monster his entire life. His beautiful partner, Ferris, is a lethal warrior with wits as sharp as her blade. Together they search for the Hero Relics, mystical artifacts that give their owners devastating supernatural abilities, to help their king give hope to a country plagued by political corruption. When they cross arms with a pair of dangerous hunters who wield several of the ancient armaments, Ferris faces Ryner in his most volatile state. As enemies wait in the shadows and blood is spilled amidst a constant threat of mutiny, for these heroes, one move could spark a war.
