The Mobile Suit Zeta Gundam side story manga Mobile Suit Z Gundam Gaiden: Mace of Judgement (Shinpan no Mace) ended in the September 2018 issue of Kadokawa’s Monthly Comic Dengeki Daioh magazine on July 27, 2018.
The story takes place in Universal Century 0089, in a period of continued tensions following the First Neo Zeon War. Earth Federation soldier Jorn has been assigned to the Salamis-class cruiser Delphoi, and it has been a year since he has seen the one he loves, Iris. The joy of their reunion is short-lived, as a message comes in from a Neo Zeon refugee asteroid base, and Earth faces a new crisis. Jorn pilots the black Gundam Gullinbursti into battle.
The manga launched in Monthly Comic Dengeki Daioh in November 2016, and the second compiled volume shipped on February 26, 2018.
