Monthly Shōnen Jump
Written and drawn by Norihiro Yagi, the individual chapters of "Claymore" began serialization in Shueisha's "Monthly Shōnen Jump" in 2001. After the magazine was discontinued, the series was moved to "Weekly Shōnen Jump", where it still was appearing once a month from July 2 to October 22, 2007. On November 2, 2007, serialization was moved to "Jump Square", Shueisha's replacement for the original "Monthly Shōnen Jump". The individual chapters are published in "tankōbon" volumes by Shueisha, which released the first volume on January 5, 2002. As of December 4, 2014, the series has concluded in Japan with 27 volumes and 154 chapters (plus epilogue).
