• Yamabuki Chidori condemned the Fourth Division staff and demanded to know why Captain Unohana had allowed Chizome Souya to treat patients.

Yamabuki Chidori tried to teach Chizome Souya medicine while juggling her duties as Chief Strategist, then refused Aizen’s request for Spirit Core Technology. Aizen interpreted her hint about the technology’s location as permission to investigate and used Kyōka Suigetsu to enter the 12th Division, where he witnessed a Wormhole experiment.

• Yamabuki Chidori corrected Chizome Souya after he frightened patients with his inept diagnoses, then asked Kamishirokawa and the others to help teach him.
• Yamabuki Chidori returned to her office, where Kuchiki Kyōka confronted her with a backlog of documents, and she finished the work before seeking Huo Ying for dinner.
• Aizen told Yamabuki Chidori he wanted to learn about Wormhole Technology and Spirit Core Technology, but she refused and said the technology was sealed in the 12th Division’s lowest level.
• Aizen left Yamabuki Chidori in charge of the Fourth Division and went to the 12th Division, reasoning that she had secretly encouraged him to obtain the technology.
• Aizen used Kyōka Suigetsu to disguise himself as Yamabuki Chidori, entered the 12th Division, and witnessed a Wormhole experiment on his way to its lowest level.

Aizen copied the 12th Division’s Spirit Core research and announced plans to form the Espada from Hueco Mundo’s strongest Menos Grande. After Nel Tu recommended Nnoitra Gilga, Aizen tested him in battle and left him crushed beneath his Reiatsu when he attacked instead of accepting defeat.

• Aizen offered Nnoitra freedom if he defeated Nel Tu, but required him to serve if he lost; Nel Tu swiftly severed Nnoitra’s arms and won.
• Nnoitra regenerated and charged at Aizen, who released his Reiatsu and slammed him to the ground.

Aizen forced Nnoitra to accept Nel Tu as his superior before returning to Soul Society, while Zendouji Yuuhin began a new life selling medicine in Rukongai. After a failed start in Gomukui District, Yuuhin partnered with Ōtōgawa Utsugi and became wealthy through a successful pharmacy.

• Aizen broke Nnoitra's arms with his Reiatsu and assigned him to serve under Nel Tu, then returned to Soul Society to maintain his cover.
• Zendouji Yuuhin arrived in Gomukui District and killed the samurai and ronin who attacked him before announcing that he was selling medicine.

• Ōtōgawa Utsugi agreed to provide money and staff while Yuuhin supplied his medicines, and they opened a pharmacy.
• Yuuhin's medicines made the pharmacy enormously successful, and he grew rich while joking that counting money was exhausting.

Zendouji Yuuhin discovered Aikawa Ramu's exceptional spiritual talent, recruited him as a pharmacy clerk, and arranged for him to enter the Shinigami world. After Aikawa Ramu reached the Seireitei, Yamabuki Chidori received him and led him inside.

• Aikawa Ramu tried to extort protection money from Zendouji Yuuhin, who defeated him twice and then hired him after realizing his talent.

• Yamabuki Chidori stopped Jidanbō, confirmed Aikawa Ramu's identity, and escorted him into the Seireitei.

Yamabuki Chidori brought Aikawa Ramu to Shino Academy, where he struggled with his first lesson and was assigned a test the next day. Kisuke Urahara gathered Aikawa, Yoruichi, and Kukaku to study at the Shihōin estate, where Yoruichi began a story about the Tsunayashiro Clan.

• Yamabuki Chidori enrolled Aikawa Ramu at Shino Academy and placed him in Yoruichi's class beside Kisuke Urahara.

Yoruichi led Kisuke Urahara, Kūkaku Shiba, and Aikawa Ramu into an abandoned Tsunayashiro Clan laboratory, where they encountered a Hollowfied Soul Reaper. After discovering the enemy could regenerate and release his Zanpakuto, Kisuke devised a plan to defeat him, and the group prepared to fight on.

• Yoruichi persuaded Kisuke Urahara, Kūkaku Shiba, and Aikawa Ramu to explore a supposedly haunted Tsunayashiro Clan laboratory in Rukongai.

Kisuke Urahara, Yoruichi, Ramu, and Kūkaku were trapped by Hollowed Soul Reapers until Yamabuki Chidori rescued them and confronted his apprentice Aizen Sōsuke about the experiments behind the monsters. Later, Yoruichi visited Yamabuki’s office as a black cat to escape the heat at the 2nd Division Barracks.

• Urahara, Yoruichi, Ramu, and Kūkaku defeated one Hollowed Soul Reaper, then found themselves surrounded by at least twenty more.

Captain-level Reiatsu clashes drew Soul Reapers toward the 11th Division, where Kuruyashiki Kenpachi and Chizome Souya fought over the new Kenpachi contest. Chizome revealed his skill in combined Kidō chanting and escalated his attack with a group of Giglio.

• The Captain Commander sent Chōjirō Sasakibe to investigate the Reiatsu clash, while Shunshun Shidō left Yoruichi tied up to see what was happening.
• Kisuke Urahara freed Yoruichi, and they headed to the 11th Division with Retsu Unohana, who identified the event as a Kenpachi contest.

• Chizome summoned two Giglio and used them to divide his Kidō incantations, striking at Kuruyashiki with powerful Hadō spells.
• Chizome summoned dozens more coffins, brought out additional Giglio, and set them ablaze.

Chizome Souya fought Kuruyashiki Kenpachi for the title of Kenpachi, using Kidō, summoned creatures, and firearms against the powerful Captain. After Kuruyashiki broke out of Black Coffin, Chizome released Bankai and silently incapacitated him, leaving the duel’s outcome in doubt to everyone but Yamabuki Chidori.

• Unohana ordered the Fourth Division to evacuate before the Giglio completed Hadō #96, One Blade Incineration, and Kuruyashiki survived the blast with minor burns.

• Chizome released Bankai, vanished his Zanpakuto, and claimed his attack had already landed.
• Kuruyashiki suddenly suffered extensive internal injuries and collapsed into a pool of blood as the onlookers failed to understand how Chizome had struck him.

Chizome Souya defeated Kuruyashiki and became the eighth Kenpachi and Captain of the 11th Division. After settling into his new role, he prepared a proposal for Central 46 to arm ordinary souls with Spirit Particle Muskets so the Shinigami could fight more Hollows.

• Chizome Souya defeated Kuruyashiki without killing him, and Kuruyashiki chose not to use Bankai because its cost was too great.
• Kuruyashiki formally passed the 11th Division captaincy to Chizome Souya, who accepted the position and told the squad members they could challenge him if they disagreed.

Meanwhile, Kisuke Urahara tested his Tenshintai with Yoruichi and unexpectedly summoned Amatsuyu Tsuru, Chizome Souya’s Zanpakuto spirit.

• Chizome Souya asked Yamabuki Chidori to increase Hueco Mundo extermination campaigns, then took his proposal to Central 46.

• Katoru Hatsunoya brought the proposal to Yamabuki Chidori, who declined to take responsibility for Central 46’s decision.
• Katoru Hatsunoya ordered every councilor to attend a meeting, and Shunshun Shidō left home while Yoruichi remained bound behind.

• After Kisuke Urahara stabbed Benihime into the Tenshintai, Amatsuyu Tsuru appeared and revealed that she was Chizome Souya’s Zanpakuto spirit.

Kisuke Urahara learned that Azashiro Souya planned to turn Kons into Hollow-fighting weapons, while Yoruichi reached Central 46 as the council began reviewing the proposal. The meeting ended with Katoru Hatsunoya weighing the plan after Azashiro admitted the modified Kons would lose their consciousness.

• Central 46 voted 24 to 20 to approve Chizome Souya’s proposal, requiring every Modified Weapon to be registered.

• Yoruichi transformed into a cat and rested with Yamabuki Chidori, who thought about the obstacles Azashiro had cleared for him.

• Kawakami asked Shunshun Shidō to investigate the disappearance, but she ordered the 2nd Division to prioritize regular duties while Kawakami sent retainers to watch Souya.
• Souya discovered the retainers monitoring him, let most of them flee, and invited Kawakami’s retainer Kimura home for lunch before sending him back with a message for Kawakami.
• Kimura told Kawakami that Souya had shown no suspicious behavior, while Kawakami reviewed surveillance recordings that revealed no trace of his missing grandson.
• Souya spent seven days trying to make Modified Weapons absorb Hollow Particles but made no progress, then went to meet Aizen when his sister rang the basement bell.

• Chizome Souya pinned the attacking retainers down with his Reiatsu and demanded that Kawakami explain the attack.
