Mayuri appears again during the Bount Invasion of Karakura Town, he is in his office when he is approached by 8th Division Captain Shunsui Kyōraku in reference to having any information on the Bounts. Mayuri flat out refuses to share any information with the inquisitive captain. Not long after Kyōraku leaves, Mayuri finds that all his files on the subject have been erased. Mayuri later calls a meeting of the captains and informs them that there is a traitor among them whom has erased the information from his database, not realizing it was former 11th Division member Maki Ichinose. Mayuri explains to the captains the history of the Bounts. Telling a story about a war between the Quincy and the Bounts, which ended in a Bount defeat. The biggest incident to come out of this defeat is the Bounts consuming living souls to increase their power. Mayuri then deduces that the number of people will increase as the Bounts become more active.

Mayuri finds the information on the Bounts and wanting a Bount test subject, he sends Nemu to give Uryū an artifact that will temporarily restore his Quincy powers in exchange for helping the Bount to reach Soul Society (which he assumes will occur). Meanwhile General Yamamoto begins suspect Mayuri of treason and send Byakuya to search in his families archives for information on the Bounts.

When the Bounts attack Soul Society, Mayuri decides to prove his loyalty by defeating one of the Bount, Sawatari. Sawatari attacks Mayuri with his doll, Baura, and manages to rip Mayuri's left arm off. Mayuri regenerates his arm with his medicine, and uses his Zanpakutō to paralyze Sawatari's doll, Baura. Mayuri then stabs Sawatari in the right arm. Baura then manages to overcome the paralysis to retreat with Sawatari into another dimension. Sawatari surfaces in another location in Seireitei, and Mayuri appears, revealing that he made a scanner to track the Bount. Sawatari attacks Mayuri with the power of other Shinigami that Baura absorbed in previous battles. Mayuri is forced to use his Bankai, and kills Sawatari. The confrontation leaves him severely injured afterwards, largely due to his persistence in trying to capture the Bount alive at first.

During everyone's rest and partying from the recent chaos, strange beings appear at the Kuchiki Manor and cause much destruction. After killing one of them, Byakuya and Rukia go to Kurotsuchi for answers. Mayuri reveals that he never stated that the Zanpakutō Spirits would be returned to their original state. He calls out a restored Ashisogi Jizō to show that they can still be summoned. He explains that several of the spirits that Muramasa manifested were not recaptured and were able to kill their masters. Kurotsuchi goes on to say that rather than dying with their partners, they changed into new creatures he deemed "Tōjū". After warning them that these rogue spirits can access their full power, equal to a Bankai, at any time, he asks them with great delight to bring back one, alive, for him to analyze. Later, Rukia succeeds in capturing one and has it sent to Kurotsuchi, who responds with great glee. Despite his joy in analyzing them, he holds no interest in actually reversing the process from Tōjū to Zanpakutō, until he feels obligating by accepting various sweets as a bribe from Lieutenant Nanao Ise. As he begins his research, he notices something about the broken Tōjū sword that catches his interest. Mayuri later accompanies the staff of the SDRI on field research. Upon their return, they discover that the SDRI's buildings have been ruined by Senbonzakura and Zabimaru, greatly annoying Mayuri.
