The Thousand-Year Blood War arc
After the death of Genryūsai Shigekuni Yamamoto, he returns to Soul Society with the other members of the Royal Guard, where they are met by most of the surviving Gotei 13 captains and Ichigo Kurosaki. Bearing a flag with the Royal Guard's emblem, he greets the assembled Shinigami before going to talk to Unohana. He asks her about the number of deaths that have occurred and wonders if she is using the healing methods he taught her. Onsō tells them to catch up later, as they have things to do, annoying him.

When Captain Suì-Fēng gives out to them about how they did not help in the battle with the Vandenreich, he grabs her and tells her that their job is to protect the Spirit King, not Seireitei and that the Gotei 13 did not live up to its name. Onsō knocks him to the ground and tells him to talk later. When Unohana objects to Senjumaru Shutara bringing the critically injured Byakuya Kuchiki, as well as Renji Abarai and Rukia Kuchiki to the Royal Palace, he tells her that they cannot fully recover with her abilities and that he can. He then tells her that it is not the time for her to focus on healing.

They later proceed to take Ichigo and some of the injured Shinigami with them to the Royal Palace, but before they leave, they are interrupted by Kisuke Urahara. He listens while Ichigo talks with Urahara before they head to the Royal Palace.
