Shibano launched the manga on May 4. Shibano started the Fairy Tail Gaiden: Rhodonite spinoff manga in "Magazine Pocket" last November, and ended it on March 30. That previous manga centered on Gajeel Redfox.
Shibano debuted Fairy Tail Gaiden: Kengami no Sōryū (Fairy Tail Spinoff: Twin Dragons of Sabertooth) in the "Magazine Pocket" app in July 2015 as a part of the app's launch. Kodansha released the manga in one compiled volume in Japan in January. Kodansha Comics will publish the compiled volume in English this fall.
