The series will begin in Gangan Joker's January 2016 issue, which ships on December 22. Gangan Joker announced in June that Mochizuki would launch a new series.
Mochizuki launched Pandora Hearts in Square Enix's Monthly G Fantasy magazine in 2006, and the manga ended this year with 24 volumes.
Yen Press licensed Mochizuki's Pandora Hearts and Crimson-Shell manga, as well as Shinobu Wakamiya's side story novel Pandora Hearts: Caucus Race, for North America. NIS America released the 25-episode anime adaptation by Xebec.
