Hiromu Arakawa, the acclaimed manga author behind Fullmetal Alchemist, has released the first image from her latest manga series.Few details are known about the as-yet untitled manga series, but it will reportedly be set in feudal Japan and will focus on the story of an archer. The new series will be serialized in Square Enix's Shonen Gangan magazine, the same publication that originally published Fullmetal Alchemist. No release date was given, but the image promises that the new manga is "coming soon."
In June, Shonen Gangan teased that it would have some new announcements to make in time for the 20th anniversary of Fullmetal Alchemist's original publication. While this new manga series doesn't seem to be related to the adventures of Edward and Alphonse, it does appears to be at least one part of the new announcements that the magazine was referring to. The next issue of Shonen Gangan, which will be released on July 12, will have the full details regarding the new manga project. Since the conclusion of Fullmetal Alchemist in 2010, Arakawa has been working on her on-going adaptation of  The Heroic Legend of Arslan manga, which is based on a series of novels by Yoshiki Tanaka. It's currently unknown if that series will continue once this new manga begins serialization.
