The Japanese anime news website Anime! Anime! confirmed on Wednesday that the new original video anime ( OVA ) of Yunosuke Yoshinaga 's Broken Blade ( Break Blade ) manga is still in the works. The anime will center on the past of the Golem Delphine and its mysterious creation, and the producers intend to make the OVA for both fans of the original story and new fans. The staff and release date for the OVA is as yet unannounced.

The manga already inspired a six-part 2010-2011 film series that Sentai Filmworks released in North America. Sentai Filmworks describes the film series:

In Cruzon, children are born with the ability to control quartz. This power allows them to levitate simple objects—or control enormous and complex mobile battle suits called Golems. But when an ancient Golem is discovered during the height of a brutal war, a Young King and his beautiful queen turn to Rygart Arrow. Though an “un-sorcerer”, Rygart can miraculously pilot this ancient and powerful weapon. But in war, school friends can turn into bitter enemies and allies have suspicious motives.

The six-part film series was recompiled into a 12-episode television anime series that premiered in April 2014, and featured previously unanimated scenes.

Tetsuro Amino ( Macross 7 , Shiki ) and Nobuyoshi Habara ( Negima! , Fafner ) helmed the 2010-2011 films, with Production I.G and Xebec handling the animation. Masashi Sogo ( Bleach , Fairy Tail , Gantz ) wrote the screenplays.
