The August 2015 issue of Shueisha’s Jump Square magazine has announced that a new quarterly magazine, titled Jump Square Crown will launch on July 17, 2015. The new magazine will publish Katsura Hoshino’s D.Gray-man and Yasuhiro Nightow’s Blood Blockade Battlefront Back 2 Back.
Shueisha ended its Jump SQ. 19 magazine in February 2015 with plans to launch a new magazine in July 2015. Blood Blockade Battlefront was running in Jump SQ. 19.
Hoshino originally launched the D.Gray-man in Weekly Shonen Jump magazine in 2004, but the manga went on hiatus numerous times due to the author’s health. The series then resumed in Jump Square magazine in 2009. The manga’s latest hiatus has been ongoing since 2013. VIZ Media is publishing the manga in English.
