Speculation has been bubbling around the manga world for a while that Kodansha would bring back Sailor Moon, which was originally published in the United States by Tokyopop (then known as Mixx) but has been out of print for years. A magical-girl story about teenage girls who transform into superheroines to fight evil, Sailor Moon was the first successful shoujo manga and anime in the U.S. and helped pave the way for the manga revolution that followed. Sailor Moon is one of those books people get sentimental about—for a lot of readers and creators, especially women, it was their first comic. It looks like Kodansha is going for those older readers, as they are describing their release as a "deluxe edition," rather than keeping them cheap for teenagers—who would probably find it laughably dated. Kids are cruel that way.
Kodansha plans to launch the new edition in September and publish a volume every two months. They will also be publishing the prequel, Codename: Sailor V, which has not been previously licensed in the U.S. They original series will follow the sequence of the 2003 Japanese re-release but collapse it from 18 volumes into 12 for the main story arc plus two more volumes of short stories. It sounds like they are doing a new translation, and the books will have new cover art and freshly retouched interior art.
