• Ailin left Urahara Kisuke’s underground base and headed toward the True Zero Spirit Arts Academy.
• Byakuya Kuchiki returned to the Kuchiki Clan estate and found Haruko Kuchiki humming happily, which he suspected was because of Ailin.

Ailin welcomed a new class of recruits to the Eleventh Division, including Gin Ichimaru, who joined to grow strong enough to investigate Aizen Sosuke and reclaim what he believed Aizen had taken from Rangiku. Ailin kept Gin behind for a private conversation after assigning the other recruits to training.

• Haruko told Byakuya that Ailin had resolved her soul condition, but she declined his method so she could keep studying at True Zero Spirit Arts Academy and pursue strength.
• Ailin forged Excalibur, then three years passed before he sent Kiyone Shunjō and Gōsuke to recruit new Eleventh Division members under his three-year survival rule.
• At True Zero Spirit Arts Academy, Aizen Sosuke invited the prodigy Gin Ichimaru to join the Fifth Division, while Gin recognized him as the man who had harmed Rangiku.
• After hearing Kiyone Shunjō describe the Eleventh Division's demanding standards, Gin refused Aizen's offer and chose to join Ailin's division for training.
• Kiyone Shunjō and Gōsuke brought the recruits to Ailin, who welcomed them and asked Kiyone to train them, then kept Gin behind to speak with him.

Ailin trained Gin Ichimaru in the Rukon District while Retsu Unohana learned of the training and prepared to confront Ailin. Unohana set out under the moonlight, as Gin demonstrated his new perception technique against three Hollows.

• Gin Ichimaru thanked Ailin for saving Rangiku and joined the Eleventh Division, where Ailin promised to train him personally.
• Yūne Kotetsu told Retsu Unohana that Ailin had taken a gifted Shinigami as his disciple and was training him in the Rukon District.

• Gin Ichimaru evaded three Hollows with precise movements while Ailin watched, satisfied with how Gin used the Shinigami version of Kenbunshoku Haki he had taught him.

Gin Ichimaru fought Zaraki under Ailin’s direction, and their battle revealed that Zaraki had unconsciously suppressed his spiritual pressure for centuries. Unohana Yachiru arrived hoping to fight Ailin, but seeing Zaraki’s weakened state shook her; the chapter ended with Zaraki recognizing her and welcoming the prospect of facing her again.

• Ailin recognized Zaraki and Yachiru Kusajishi, then sent Gin Ichimaru to fight Zaraki instead of accepting Zaraki’s challenge himself.
• Gin used Observation Haki to battle Zaraki, who grew excited and further suppressed his spiritual pressure as they fought.
• Unohana Yachiru arrived and realized Zaraki’s weakness resulted from his habit of holding back to enjoy fighting her, which filled her with shame.
• Gin withdrew after exhausting his spiritual power, and Ailin praised him for preserving himself against a stronger opponent.
• Zaraki spotted Unohana and laughed, recalling their earlier battle and anticipating another fight with her.

Ailin fought Zaraki after Zaraki challenged him, and their battle awakened Zaraki’s suppressed reiatsu before Ailin’s final strike left him gravely injured. Retsu Unohana took Zaraki and Yachiru back to Seireitei for treatment, leaving Gin Ichimaru to ask Ailin who Zaraki was and what connected him to Captain Unohana.

• Zaraki challenged Ailin, who accepted and introduced himself as Ailin Kenpachi of the Eleventh Division.
• Ailin repeatedly wounded Zaraki, whose joy in the battle caused his suppressed reiatsu to rise to ordinary Captain-level strength.

• Retsu Unohana treated Zaraki, then used Flesh Rip to swallow him so she could heal his severe injuries.
• Retsu Unohana took Yachiru with her as she flew back to Seireitei, and Gin Ichimaru asked Ailin about Zaraki and Captain Unohana.

Gin Ichimaru learned that Retsu Unohana had once been the First Kenpachi, while Unohana asked Genryūsai Shigekuni Yamamoto to teach Zaraki swordsmanship. Zaraki woke in the Fourth Division and, seeing Unohana’s gentle facade, concluded he was still too weak to bring out her true self.

• Ailin explained to Gin Ichimaru that Retsu Unohana had been the original Eleventh Division captain and the First Kenpachi, and said he believed he could defeat her.

• Zaraki woke in the Fourth Division, learned that Yamamoto would teach him, and decided he was too weak to make Unohana show her true nature.

Zaraki challenged Ailin after overwhelming the Eleventh Division, but Ailin defeated him and recruited him as his Vice-Captain by promising future swordsmanship-only duels. Later, Gin Ichimaru killed a Fifth Division Shinigami in front of Aizen Sosuke, who questioned Gin about the killing.

• Zaraki recovered from his injuries, began training under Genryūsai Shigekuni Yamamoto, and eventually stopped attending after learning only a two-handed sword swing.
• Zaraki returned to the Eleventh Division and defeated its members until Ailin arrived and swiftly overwhelmed him with spiritual power and Kido.

• Ailin left Zaraki in charge of the Eleventh Division and returned to the Kuchiki Clan, while Gin Ichimaru continued practicing in the Rukon District.
• Gin Ichimaru killed a Fifth Division Shinigami with Shinsō, and Aizen Sosuke questioned him about provoking a conflict between their divisions.

Gin Ichimaru sought to join the Fifth Division so he could grow stronger and get close to Aizen Sosuke, but Aizen brought the transfer request to Hirako Shinji. Hirako visited Ailin to discuss Gin and warn him that he distrusted Aizen.

• Gin Ichimaru challenged Aizen Sosuke to help him transfer from the Eleventh Division to the Fifth Division, claiming he needed stronger instruction to overcome a training bottleneck.
• Aizen agreed to discuss Gin's transfer with Hirako Shinji, the Fifth Division captain, before asking Ailin to approve it.
• Ailin left a chess game with Haruko to meet Hirako at the Kuchiki Clan estate.
• Hirako told Ailin that Aizen had recommended Gin for the Fifth Division and that he distrusted his vice-captain despite having found no proof of wrongdoing.

Ailin persuaded Hirako Shinji to give Aizen more trust, beginning with Gin’s possible transfer to the Fifth Division. Ten years later, Ailin and Zaraki fought their scheduled Zanjutsu duel, where Zaraki’s instincts and spiritual pressure awakened enough for him to contend with Ailin.

• Ailin argued that Hirako should trust Aizen more, and Hirako agreed to let Aizen handle division affairs while considering Gin’s transfer.
• Ailin asked Hirako to look after Gin if he joined the Fifth Division and to let Ailin see him off if Aizen was exposed.
• Ailin reflected that Gin could make his own choices, though Ailin planned to watch over him during the Battle of Karakura Town.
• Ten years after Zaraki became the Eleventh Division vice-captain, he challenged Ailin to their agreed Zanjutsu-only battle in Zaraki District.
• Ailin and Zaraki traded powerful sword strikes, sending shockwaves across the area and forcing Eleventh Division members to watch from a distance.
• As the duel continued, Zaraki’s instincts awakened and his suppressed spiritual pressure erupted, letting him barely contend with Ailin.

• Ailin unleashed a massive reiatsu slash, defeated Zaraki, and treated his injuries after acknowledging his fighting spirit.
• Yachiru Kusajishi and Kiyone Shunjō arrived, and Ailin assigned Kiyone responsibility for the Eleventh Division while Zaraki recovered.
• Ailin suspected Aizen Sosuke and Gin Ichimaru had watched from the shadows, and the two discussed Ailin's strength and Aizen's Kyoka Suigetsu.
• Ailin asked Urahara Kisuke to make Zaraki a reiatsu-absorbing eyepatch and suggested bells for his hair to help enemies track him in battle.
• Zaraki became more determined to improve his swordsmanship and grow stronger before challenging Ailin again in ten years.

Ailin forged Ace in his Inner World and absorbed the battle memories of Pirate King Roger. Captain-Commander Yamamoto then asked him to help Kensei Muguruma escort the King's Seal, and Ailin accepted.

• Ailin forged Ace, absorbed Roger's battle memories, and placed the sword beside Gryphon in Sword Hill.
• A Hell Butterfly summoned Ailin to the First Division, where Yamamoto asked whether he could trust him.
• Yamamoto explained that the King's Seal was being relocated and that he suspected someone was weakening the Gotei 13 before the escort.
• Yamamoto assigned Ailin to assist Kensei Muguruma with this year's escort, and Ailin agreed.

Ailin planned to seize the King's Seal so he could study its spatial power, and gathered his manifested Zanpakuto in Unlimited Blade Works to organize the operation. Gol D. Roger, Red-Haired Shanks, and Kirito volunteered, while Ailin ruled out several others whose abilities he had already used in Soul Society.

• Ailin entered Unlimited Blade Works and summoned the manifested Zanpakuto with Muramasa.
• Ailin explained that he wanted the Zanpakuto to attack the King's Seal's escort, then disappear back into his Inner World after he pursued them.
• Gol D. Roger volunteered despite learning that participants could not be summoned again in Soul Society, and Ailin assigned him as the first candidate.
• Ailin said the plan needed four more Captain-level Zanpakuto and rejected Inuyasha, Sesshomaru, Fanatio, and Koshiro Shimotsuki because he had used their powers before.
• Red-Haired Shanks and Kirito volunteered to join the operation.

• Ailin approved Kirito, Murakumo-no-Tsurugi, and March of the Dead: Yatsufusa as part of the five Zanpakuto chosen to participate, and gave Yezora the projected sword Dark Repulser.

• Kensei Muguruma found Roger's group on the third day, well before they expected the convoy to arrive, and the ambushers realized his scouting range exceeded their estimates.

• Roger struck Ailin with Kamitsuchi, shattering his Dankū barrier, while the Ninth Division fought off the skeletons.
• Ailin battled Roger and Shanks with his Zanpakuto and Kido as the Soul Reapers kept the skeletal Hollows from reaching the palanquin.

Ailin rescued Kyunnanbyaku and recovered the King's Seal after the Ninth Division was devastated by Setsuna Take's skeletal army. While Kensei Muguruma kept watch in a cave, Ailin analyzed the seal and completed Tetsusaiga, leaving Tensōjū as a future challenge.

• Setsuna Take defeated Kyunnanbyaku, took the King's Seal, and attacked her, but Ailin rescued her and carried her away.
• Yezora defeated Kensei Muguruma after a fierce fight, and Ailin arrived in time to save the badly wounded captain.
• Ailin told Kensei Muguruma that all the Ninth Division Seat Officers except Kyunnanbyaku had been killed, then asked him to keep watch while he recovered.
• Kensei Muguruma found the bandaged Kyunnanbyaku in the cave and stood guard as Ailin entered his Inner World to study the King's Seal.
• Ailin analyzed the King's Seal's spatial power and used Enhancement magic to complete Tetsusaiga as Meido Tetsusaiga.
• Ailin considered Tensōjū's power to revive the dead but could not yet determine how to complete it.

After analyzing the King's Seal, Ailin forged a Zanpakuto with its spatial power and set out with Kensei Muguruma to recover it. He found Roger and the others, who challenged him for the title of Kenpachi, and the battle began.

• Ailin suspected the Seireitei had allowed the King's Seal theft to draw out its enemies, then decided to end the escort mission after Kensei Muguruma recovered.
• Ailin persuaded Kensei Muguruma to pursue the thieves with him and assigned him the armored man while Ailin held off the other four.
• Ailin used Bakudo #55—Grasping Cicada to locate Roger and the others, who had deliberately waited nearby with the King's Seal.
• Roger and Shanks declared that they would defeat Ailin and claim the name Kenpachi, wagering the King's Seal on their fight.
• Ailin accepted the challenge and opened the battle with a massive slash that carved a deep ravine toward Roger and the others.

• Ailin powered up with reiatsu and drove Roger, Shanks, and Yezora back, while Black Pupil sacrificed her seven Adjuchas to strengthen the last one.
• Ailin cut down Black Pupil's final Adjuchas, making her the first of the five attackers to leave the battle.

Ailin used Tetsusaiga’s new spatial power to defeat Kirito, Roger, and Shanks, while Kensei Muguruma fought Setsuna Take. Kensei avenged Shiro by severely injuring Setsuna, and Ailin recovered the damaged Zanpakuto after the operation to seize the King's Seal succeeded.

• Kirito attacked Ailin with Eclipse, but Ailin used Meido Tetsusaiga to swallow the strike and then engulfed Kirito in Meido Full Moon Break.

• Ailin learned that the Ise Family head and her husband had died, leaving Ise Nanao alone while the nobles argued over the Eight Mirror Sword.
