CLAMP announced yesterday that their popular manga series Kobato will print its final chapter in the August 2011 issue of Shoten's Newtype magazine. The issue will go on sale July 10, 2011.
CLAMP began serialization of the manga in Newtype magazine back in 2006 and in Newtype USA back in 2007. Since then there have been three volume releases in North America, with the fourth coming in July. An anime series based on the manga also ran in Japan from 2009 to 2010 and is slated for a North American release in August.
