Chapter Summaries

Aizen investigated the cleared battle site and learned from Xuanxin how a concealment device could hide Reiatsu from even a careful observer. As the Tsunayashiro Clan’s secret soul fusion experiment collapsed, Yoruichi’s investigation found a breakthrough, and Shaoling Fon summoned Xuanxin to hear the news.

• Aizen deduced that the traces at the ruins suggested deliberate manipulation rather than an ordinary Hollow attack, and Xuanxin revealed that the Stealth Force patrols were a decoy.
• Xuanxin demonstrated a concealment device that had hidden his Reiatsu from Aizen, then reclaimed it and sent Aizen back to the academy.
• The Tsunayashiro Clan’s unstable soul fusion experiment erupted at a secret Rukongai base, leaving an underground crater and no clear evidence of the laboratory.
• Yoruichi found a major breakthrough beneath the ruins, and Shaoling Fon came to the 11th Division training ground to summon Xuanxin.
• Shaoling Fon told Xuanxin that Yoruichi had said, “Found it,” and Xuanxin recognized her as a member of the Fon Clan.

Xuanxin and Yoruichi traced the explosion to a stronghold linked to the Tsunayashiro Clan and planned a private gathering as cover for their move that night. The Tsunayashiro Clan head misread the gathering as a political meeting and ordered his people to watch it while moving the experimental materials to a backup laboratory.

• Yoruichi showed Xuanxin a scorched storage-device fragment containing records of artificially modified Reiatsu and identified a new buyer of its special material.
• Xuanxin told Yoruichi they would make their move that night, then insisted they host a party before assembling the troops.
• Shaoling Fon secretly recorded Xuanxin and Yoruichi’s exchange in her pink notebook, while Xuanxin invited Sōsuke Aizen to the gathering.
• Xuanxin personally invited Ginrei Kuchiki and his senior brothers, then booked an upscale tavern near the Eighth Division.
• The Tsunayashiro Clan head learned of the explosion and the planned gathering, wrongly concluded that the Shihoin and Kuchiki Clans were forming an alliance, and ordered surveillance of the tavern and the transfer of experimental materials to a backup laboratory.

Xuanxin and Yoruichi used a staged tavern gathering to expose Tsunayashiro Clan spies and launch a coordinated operation against the clan’s backup base. The base was surrounded as the Tsunayashiro Clan head grew suspicious and sent more scouts to check it.

• Xuanxin, Yoruichi, Ginrei Kuchiki, Shunsui Kyōraku, Ukitake, and Aizen gathered at the tavern under the cover of a private banquet.
• A disguised Tsunayashiro Clan spy entered the private room, and the guests pretended not to notice him while he observed them.
• Xuanxin revealed that he and Yoruichi had evidence linking the Tsunayashiro Clan to Hollow attacks and led Ginrei and Aizen out through a concealed door.
• Shaoling Fon and the Stealth Force captured the tavern spies and escorted them to the Second Division’s underground cells.
• Kisuke Urahara led Second and 11th Division forces in surrounding the Tsunayashiro Clan’s backup base.
• After receiving a spy’s report that everything was normal, the Tsunayashiro Clan head remained uneasy and sent two more scouting groups to the tavern and base.

Captain-Commander Yamamoto imposed a lethal curfew across Seireitei, trapping the Tsunayashiro Clan’s forces and crushing the clan head’s ambitions. Meanwhile, Xuanxin’s group reached the Tsunayashiro stronghold, where Ginrei Kuchiki prepared to witness the investigation.

• Yamamoto noticed the scouts in Seireitei and ordered Sasakibe to impose a curfew, threatening to kill anyone who left without written authorization.
• Xuanxin’s Second Division militia ambushed and captured the Tsunayashiro Clan’s second group of scouts.
• Sasakibe blocked the Tsunayashiro Clan’s private army from leaving Seireitei, and Yamamoto’s overwhelming Reiatsu forced the fighters to submit.
• The Tsunayashiro Clan head gave up hope and ordered preparations for the next clan head’s succession ceremony.
• Xuanxin, Yoruichi, Ginrei Kuchiki, and Aizen arrived at the stronghold, where Kisuke Urahara reported that he had sealed its exits.
• Xuanxin explained that Ginrei’s role as a witness would help establish proof of the Tsunayashiro Clan’s illegal soul experiments, and Ginrei drew his Zanpakuto.

Xuanxin and Yoruichi led the 11th and Second Divisions in a successful raid on the Tsunayashiro Clan’s underground laboratory, uncovering evidence of horrific soul experiments and a plan to build an army capable of overthrowing Soul Society. Aizen secretly stole a hidden notebook as Xuanxin prepared to take the discoveries to Captain-Commander Yamamoto.

• Xuanxin and Yoruichi directed a coordinated assault that overwhelmed the Tsunayashiro Clan’s guards and stopped the researchers from destroying the evidence.
• Ginrei Kuchiki, Xuanxin, Kisuke Urahara, and Aizen entered the laboratory and found records and mutilated Rukongai souls in cultivation chambers.
• Xuanxin stopped Aizen from taking the black research books, but Aizen later secretly drew a sealed notebook from a waste tank with Bakudō #4: Hainawa.
• Xuanxin and Yoruichi discovered modified souls resembling Sōya Azashiro’s experimental specimens and realized the Tsunayashiro Clan intended to create monsters to overthrow the Gotei 13 and Soul Society.
• Xuanxin ordered the 11th Division lieutenant and Kisuke Urahara to secure the laboratory while he, Yoruichi, and Ginrei prepared to bring the evidence to Captain-Commander Yamamoto.

Xuanxin and Yoruichi exposed the Tsunayashiro Clan’s conspiracy to the Gotei 13, prompting Yamamoto to arrest the clan and impose a sweeping military judgment. The clan head was imprisoned in Muken, while his family was stripped of power and ordered into two hundred years of seclusion.

• Xuanxin sent Aizen back to Shin'ō Academy and ordered him to keep the night’s events secret.
• Xuanxin, Yoruichi, and Ginrei Kuchiki reached the First Division Barracks, where Soi Fon presented the captured Tsunayashiro witnesses and evidence to the captains.
• Xuanxin revealed that the Tsunayashiro Clan had abducted wandering souls for experiments based on Sōya Azashiro’s work and plotted to overthrow Soul Society.
• Yamamoto ordered the Tsunayashiro Clan placed under investigation and arrested, and Yoruichi and Soi Fon brought its head to the assembly hall.
• Yamamoto announced a military judgment deposing and imprisoning the clan head in Muken, stripping the clan of its political privileges and control of the Great Spirit Book Gallery, and imposing two hundred years of seclusion on its core members.
• The Tsunayashiro Clan head read the sentence in prison and cried out in despair over the two-hundred-year exile.

After the Tsunayashiro Clan’s conspiracy ended, Xuanxin explained to Aizen why he had chosen gradual reform over a purge and revealed his long-term plan to change Soul Society. Aizen left their conversation with a new understanding of Xuanxin’s ambitions and his view that power and knowledge must go together.

• The Tsunayashiro Clan selected a low-profile young man as its new head and withdrew from public life, while nobles and civilians adjusted to stricter order in Seireitei.
• Xuanxin avoided Retsu Unohana after missing a month of swordsmanship lessons and waited at Shin'ō Academy for Aizen to speak with him.
• Aizen asked Xuanxin about the divide between nobles and commoners, and Xuanxin said nobles should bear obligations alongside their privileges.
• Xuanxin called the Central 46 corrupt but argued that destroying it and purging the Tsunayashiro Clan could trigger a civil war that would devastate ordinary people.
• Xuanxin told Aizen that he intended to change Soul Society gradually over two hundred years, and Aizen recognized the scale of his ambition.
• Aizen asked whether power or hidden knowledge was the right path, and Xuanxin answered that neither could be separated from the other.

Xuanxin gained Yamamoto’s permission to visit the Great Spirit Book Gallery, then faced Retsu Unohana after skipping her training for a month. Unohana revealed her identity as the original Kenpachi and unleashed Bankai, forcing Xuanxin to answer with his own.

• Aizen asked Xuanxin whether a Soul Reaper could break beyond their limits, and Xuanxin encouraged him to believe a pioneer might one day do so.
• Aizen began privately seeking Xuanxin’s guidance more often, making Yoruichi wary of their growing closeness.
• Yamamoto invited Xuanxin to visit the Great Spirit Book Gallery, which held records about Soul Society’s history and the origins of the three worlds.
• Xuanxin went to the Fourth Division for training, where Unohana confronted him for missing her lessons and revealed her other name before activating Bankai: Minazuki.
• Unohana flooded the dojo with blood and challenged Xuanxin, who released Bankai: Six Realms and Five Rings: Kurikara, but its Wisdom King phantom was suppressed.

After Captain-Commander Yamamoto ordered Xuanxin and Yoruichi to enter the Great Spirit Book Gallery the next day, Yoruichi grew suspicious of Xuanxin’s relationship with Retsu Unohana. The two set out for the Gallery the following morning, though Yoruichi had little interest in its history or secrets.

• Captain-Commander Yamamoto ordered Xuanxin and Yoruichi to report to him the next day to enter the Great Spirit Book Gallery.
• Yoruichi watched Xuanxin closely on their way back to the Shihoin Clan’s residence and demanded to know what was happening between him and Captain Unohana.
• Xuanxin insisted that nothing had happened beyond their intense training fight, and Yoruichi warned him to stay away from Captain Unohana and other women.
• Xuanxin agreed to Yoruichi’s warning, easing her suspicion enough to end her interrogation.
• Xuanxin and Yoruichi headed to the First Division early the next morning, with Yoruichi showing little interest in the Great Spirit Book Gallery’s history or political secrets.

Xuanxin uncovered the truth of the Soul King's betrayal in the Great Spirit Book Gallery and studied records that raised further questions about Aizen and Gigai research. Yamamoto then asked what Xuanxin intended to do about a world founded on sin, leaving Xuanxin's answer unresolved.

• Yoruichi accompanied Xuanxin to the Great Spirit Book Gallery, where she transformed into a cat and slept on his shoulder while he searched the records.
• Xuanxin learned that the founders of the Five Great Noble Clans had betrayed and mutilated the Soul King, using him as the foundation of the three realms.
• Xuanxin decided that the world's future mattered more than its past and found detailed archives about himself, Aizen, and Kirio Hikifune's Gigai experiment.
• A Hell Butterfly signaled that their time was up, and Chōjirō Sasakibe told Xuanxin that Yamamoto was waiting for him.
• Yamamoto asked whether Xuanxin had seen the truth and what he intended to do about the world's original sin, then poured him tea as Xuanxin paused before answering.

Xuanxin told Captain-Commander Yamamoto he wanted gradual reform, and Yamamoto agreed to discuss the plan with Kyōraku and Ukitake. Meanwhile, Aizen accepted the Tsunayashiro Clan’s offer of access to the Great Spirit Book Gallery and met its envoy in secret.

• Xuanxin argued that Soul Society should pursue gradual reform, and Yamamoto invited him to bring Kyōraku and Ukitake for a proper discussion.
• Yamamoto warned Xuanxin to behave himself in public, leaving Xuanxin confused before he departed.
• Aizen studied the stolen notebook but found it lacked the core theory he needed, while a hidden watcher observed him.
• A Tsunayashiro Clan agent delivered a letter offering Aizen secret access to the Great Spirit Book Gallery in exchange for serving as the clan’s outside proxy.
• Tokinada judged the clan head’s plan reckless but chose to wait for the elders to fail.
• Aizen rejected the safer option of telling Shihoin Genshin and went alone to meet the Tsunayashiro envoy in an abandoned Rukongai warehouse.

Aizen infiltrated the Great Spirit Book Gallery, learned the truth about the Soul King, and resolved to surpass the limits of a Soul Reaper while hiding his ambitions from Shihoin Genshin. The next day, Xuanxin met Sajin Komamura and agreed to support him when he entered Shin'ō Academy.

• Aizen accepted the Tsunayashiro Clan's mission and used its jade slip to enter the Great Spirit Book Gallery.
• Aizen discovered that the Soul King was a mutilated captive and decided to break the limits of a Soul Reaper, overthrow the existing order, and take the throne himself.
• Aizen recognized Shihoin Genshin as his future opponent but chose to remain a good student while they each pursued their plans.
• Captain-Commander Yamamoto introduced Sajin Komamura to Xuanxin and said he intended to recommend him for Shin'ō Academy.
• Xuanxin welcomed Komamura's admission and promised to watch over him, warning that he might face prejudice from other students.

Xuanxin assured Captain-Commander Yamamoto that his envisioned new order would include every race, and Yamamoto accepted him as the successor who could lead Soul Society’s future. Later, as Temporary Soul Technology neared completion, Yoruichi learned her father had a baby son and tried to hand him her responsibilities, only to be rebuked by Shihoin Seigen.

• Captain-Commander Yamamoto asked whether Xuanxin’s new order would include outcasts like Sajin Komamura, and Xuanxin declared that all souls would be born equal.
• Captain-Commander Yamamoto praised Xuanxin as a better successor, then chased him out when he asked for lunch and risked provoking a kendo match.
• Sōsuke Aizen’s daily exposure to Xuanxin’s ideals shifted his thinking toward creating a better world rather than simply destroying the old one.
• Kirio Hikifune’s Temporary Soul Technology neared completion, while Kisuke Urahara contributed to the research and began envisioning a vessel that could conceal Reiatsu.
• Yoruichi learned that Shihoin Seigen had fathered Yushiro Shihōin Sakimune and proposed giving the month-old baby the clan headship and her captaincy, but Seigen refused and defended the childhood he had given her.

Kirio Hikifune left Soul Society to join Zero Division as the Gotei 13 underwent a changing of the guard. Sōsuke Aizen began his plan to build a new order in Hueco Mundo and tried to place Xuanxin under Kyōka Suigetsu’s hypnosis, but Xuanxin looked away at the moment of its release.

• Kirio Hikifune departed for the Soul King Palace aboard the Tenchūren, while new captains including Shinji Hirako, Kensei Muguruma, and Rōjūrō Ōtoribashi took their posts.
• Aizen decided to create a new world in Hueco Mundo to compete with Xuanxin’s reform of Soul Society.
• Aizen asked Xuanxin to guide him in releasing his Zanpakuto so he could prepare for a Fifth Division Seated Officer examination.
• Xuanxin sensed danger but agreed to meet Aizen in the 11th Division’s underground dojo.
• Aizen released Kyōka Suigetsu, but a sudden burning pain made Xuanxin look down and miss the blade’s shifting light.

Kisuke Urahara recruited Mayuri Kurotsuchi to the Shinigami Research and Development Institute, while Sōsuke Aizen secretly hypnotized the Gotei 13’s upper ranks and sought allies. Aizen approached Kaname Tōsen, whose friend was suffering under Tsunayashiro Tokinada’s household, and began questioning Xuanxin’s reforms.

• Kisuke Urahara brought Mayuri Kurotsuchi out of the Maggot's Nest and offered him a position as his second-in-command at the Shinigami Research and Development Institute.
• Kisuke Urahara considered how to transcend the limits of Shinigami and began investigating the boundary between Shinigami and Hollows.
• Sōsuke Aizen used supposed requests for guidance to hypnotize nearly every member of the Gotei 13's upper ranks with Kyōka Suigetsu.
• Sōsuke Aizen chose Kaname Tōsen as a potential ally because he was naturally immune to Kyōka Suigetsu.
• Kaname Tōsen sensed his friend's despair in Tsunayashiro Tokinada’s household, where she endured cold treatment and humiliation despite surviving.
• Sōsuke Aizen approached Kaname Tōsen and began criticizing the limits of Xuanxin’s efforts to curb the nobles.

Sōsuke Aizen recruited Kaname Tōsen and secretly pursued a way to break the boundary between Soul Reapers and Hollows, eventually discovering a starving girl in Rukongai who appeared to carry a fragment of the Soul King. He prepared to extract it while maintaining an alibi in the Fifth Division, as the operation to capture the girl began.

• Aizen persuaded Kaname Tōsen to follow him by promising the strength to change Kakyō’s fate and achieve true justice.
• Aizen built a secret laboratory with the Tsunayashiro Clan’s support and abducted spiritually gifted souls to fuel his experiments.
• After his research stalled, Aizen searched Soul Society for a fragment of the Soul King and detected an ancient, higher-dimensional presence within a golden-haired girl in Rukongai.
• Aizen confirmed that the girl likely carried a severed part of the Soul King and designed a Reishi extractor, despite knowing its use could destroy her soul.
• Aizen arranged for Kaname Tōsen to deliver the extractor and the girl’s location to three low-ranking Soul Reapers, then stayed at the Fifth Division barracks to establish an alibi.
• While Aizen worked beside Shinji Hirako in the captain’s office, the operation to capture the girl began in Inuzuri, the seventy-eighth district of Rukongai.

Shihoin Genshin rescued a starving Rangiku Matsumoto from three Soul Reapers attempting to extract her Reishi, though the attackers killed themselves before he could interrogate them. He found a Tsunayashiro Clan crest on their device and carried the unconscious girl away, while a silver-haired boy hurried back to the alley.

• Three Soul Reapers sent by Kaname Tōsen pinned the starving Rangiku Matsumoto down and prepared to use a Reishi Extractor on her.
• Shihoin Genshin sensed the group, rushed to the alley, and overwhelmed the three Soul Reapers when they tried to flee.
• The three Soul Reapers bit poison capsules and died before Genshin could question them.
• Genshin found a Tsunayashiro Clan crest on the extractor and ordered his recruits to take the device to Captain Urahara for analysis.
• Genshin carried the unconscious Rangiku away, and a thin, short silver-haired boy hurried back to the alley.

Gin Ichimaru followed the Shinigami who had taken Rangiku and was brought back to Seireitei, where Xuanxin arranged for both of them to receive help. Xuanxin gave Kisuke Urahara a Tsunayashiro Clan device to analyze, while Aizen learned his operation had failed because Xuanxin had intervened again.

• Gin Ichimaru tracked the Shinigami who took Rangiku, bluffed his way into their group, and was brought before Xuanxin.
• Xuanxin saw through Gin's act but brought him to Seireitei, arranged a guest room and meal for him, and carried the unconscious Rangiku to the Fourth Division.
• Retsu Unohana admitted Rangiku for treatment, and Xuanxin took a sealed Reishi extractor bearing the Tsunayashiro Clan crest to Kisuke Urahara for analysis.
• Xuanxin warned Kisuke Urahara to keep ethical limits in his research, and Kisuke assured him that he had his own boundaries.
• Kaname Tōsen told Sōsuke Aizen that the mission had failed, the three operatives had taken poison, and Xuanxin had seized the extractor.
• Aizen recalled that Xuanxin had also disrupted his earlier plan and wondered whether the repeated interference could really be coincidence.

Rangiku Matsumoto woke in the Fourth Division infirmary after Xuanxin rescued her, and Yoruichi inspected the girl before confronting Xuanxin at home. Yoruichi arranged a day off for them both and kept Xuanxin occupied overnight, leaving him exhausted the next morning.

• Rangiku Matsumoto woke in the Fourth Division infirmary, where Yoruichi examined her and then left without questioning her.
• Retsu Unohana watched Yoruichi leave and remarked that some rules were better left for Yoruichi to handle herself.
• Yoruichi confronted Xuanxin about rescuing Rangiku, but his joking explanation softened her jealousy.
• Yoruichi ordered Soi Fon to tell Captain-Commander Yamamoto that she and Xuanxin were taking the next day off.
• Yoruichi challenged Xuanxin to bring Rangiku home the following day, and Xuanxin emerged from the residence the next morning exhausted.

Xuanxin struggled to avoid Retsu Unohana after realizing she had developed a possessive interest in him, while Yoruichi appeared to share an understanding with her. The chapter ended with Yoruichi arranging a home and living expenses for Rangiku Matsumoto and Gin Ichimaru in Seireitei.

• Xuanxin fled the Fourth Division dojo after Retsu Unohana revealed her predatory interest in him.
• At the captains' meeting, Xuanxin watched anxiously as Yoruichi Shihōin and Retsu Unohana exchanged knowing smiles instead of fighting.
• Shunsui Kyōraku mistakenly admired Xuanxin for supposedly keeping the two women in harmony, while Captain-Commander Yamamoto stopped lecturing him and increased the force of their sparring sessions.
• After Rangiku Matsumoto recovered at the Fourth Division's General Infirmary, Yoruichi gave Gin Ichimaru keys to a Seireitei house and promised them monthly living expenses.
