07-Ghost is a Japanese manga series written and illustrated by Yuki Amemiya and Yukino Ichihara. It is set in a fantasy world with different laws, kingdoms, gods and magic. It was serialized in Monthly Comic Zero Sum, a josei manga magazine published monthly by Ichijinsha. Seventeen bound volumes have been released by the publisher. The manga was originally licensed by Go! Comi for release in North America, but they stopped publishing in October 2009 and Viz Media has since picked up the license for the series. The series has been adapted into a drama CD and an anime television series from Studio Deen, which debuted in April 2009. 07-Ghost won a double-first prize in the third Zero-Sum Comics Grand-Prix, meaning it was chosen for first place by both readers and editors.
