Knight of Black. As Einberg, he is dispatched to Abashiri Prison. When Rozé and the Seven Luminaries Cluster raid the prison, he leads his troops to intercept them, and realizes that Ash is "Ash Phoenix" during the confrontation. In battle, he employs tactics that utilize the shield of his unit, but is defeated and killed after Ash points out his overreliance on the machine's capabilities.
