Monthly Dragon Age
The original manga by Hinata Takeda began serialization in Fujimi Shobo's "Dragon Age Pure" magazine on June 29, 2006, before moving to "Monthly Dragon Age" from June 9, 2009. Two "tankōbon" volumes were released between December 8, 2007 and June 9, 2009. The manga remains unfinished due to Takeda's death from an unspecified disease in January 2017.
