和月伸宏
is a Japanese manga series written and illustrated by Nobuhiro Watsuki. It follows Kazuki Muto, who becomes an alchemical warrior in the battle against alchemical monsters known as homunculi. Watsuki envisioned the manga as his last "shōnen" manga, and then he tried to do as much as he could with that genre. It was serialized in publisher Shueisha's "Weekly Shōnen Jump" magazine from June 2003 to April 2005. The individual chapters were republished by Shueisha in ten "tankōbon" (bound volumes). The series has been licensed by Viz Media for North American release.
