Yoshitaka Nagayama debuted in a supplemental booklet packed in with the December 2013 issue of Saikyō Jump, with Dragon Ball Heroes: Rookie Charisma Mission Episode 0 depicting the daily life and “training” of Engineer Yoshito and new Battle Navigators Tsubasa and Momo-chan in a cartoony style. The series eventually received its own standard serialization in Saikyō Jump beginning in the July 2014 issue, followed by the traditional story serials of Dark Demon Realm Mission! beginning in the September 2016 issue, Universe Mission beginning in the May 2018 issue, and now the latest and current series, Big Bang Mission!!!, beginning in the May 2020 issue.
While no listings appear to be live yet, previous volumes of Big Bang Mission! and Universe Mission!! have retailed for ¥400-440, containing various chapter totals according to the changing page lengths.
Today’s release of the November 2020 issue of Saikyō Jump — still available for purchase on Amazon Japan — features cover artwork from Nagayama, as well as the fourth Big Bang Mission!!! chapter.
