The manga began serialization in 2004 in the "Weekly Shōnen Jump" magazine, published by Shueisha. Production of the series was suspended several times because of Hoshino's health problems. "D.Gray-man" made the transition from a weekly to a monthly series in November 2009, when it began serialization in "Jump Square". In December 2012, the series went on indefinite hiatus. It resumed serialization in July 2015 after the release of "Jump SQ.Crown", a spin-off from the magazine "Jump SQ". After "Jump SQ.Crown" ceased its publication, the series was switched to "Jump SQ.Rise", starting in April 2018. The manga's chapters have been collected in twenty-seven "tankōbon" volumes as of August 2020. By March 2020, Viz Media had released 26 volumes in North America.
