More Information on the Future of Monthly Jump Serializations

Although some manga series will be temporarily serialized in Shonen Jump after Monthly Shonen Jump cease publication, Mahou Tsukai Kurohime will be serialized on the website of the "new magazine" (that will replace Monthly Jump), and the author of Kurohime will serialize a new manga on the "new magazine."

Also mentioned is that a new chapter of Claymore will appear on Weekly Jump issue 31 (7/2), and that the new Rosario + Vampire anime will have the same cast as the Rosario + Vampire Drama CD.

The final destinations of other works from Monthly Jump have not be decided yet, so for now they are going to be serialized in Weekly Jump.
