The Thousand-Year Blood War arc
Upon receiving the orders of Yhwach, Äs and the other Stern Ritter gather at the Gate of the Sun before traveling to the Seireitei in order to participate in the conquest of Soul Society. Once there, he blocks Renji Abarai's attempts to attack Äs Nödt. When Äs' hand is severely cut by Byakuya Kuchiki, Mask berates his ally, but is quickly knocked down by Byakuya. As the battle between Äs and Byakuya and Renji continues, Mask once again stops Renji from attacking, this time damaging his Shikai as the lieutenant tries to activate his Bankai. Äs criticizes him for doing so, stating that he could have stolen Renji's Bankai. Mask states that he thought only captains had Bankai, earning him a rebuke from Äs.

And just a single hit from this move, incapacitated the remarkably durable Shinigami.
