• Ten retched white substance and hurried toward the Fourth Division while suppressing his Hollow Reiatsu, and Yoruichi followed before Retsu Unohana reassured her that Ten would recover.
• Ten met the classical beauty in his inner world, where she showed him a vast sea of blood and reminded him why he had come to the world of Shinigami.
• Ten embraced the prospect of opposing Soul Society and claimed the palace’s dragon throne, while the classical beauty explained how the blood moon, sea of blood, palace, and island creatures would change as he grew stronger.
• Ten encountered a Hollow double that resembled him, and the classical beauty explained that it was unconscious and could be controlled by fusing with it, though it would stop growing unless strengthened by Hollow methods.
• Ten agreed to fight and fuse with the Hollow double before it changed, and the classical beauty told him to lower the palace so he could pull the double out of the sea of blood and defeat it.

Ten Unohana fought and fused with his Hollow, gaining control over its powers and the sea of blood while learning his Zanpakuto spirit’s name, Blade of Slaughter. Outside the Zanpakuto world, Retsu Unohana contained his Hollow Reiatsu and worried over his condition as he gradually settled down.

• Ten Unohana’s plan was revealed: a massacre in Rukongai.

Ten Unohana slaughtered his way through Zaraki District and entered Kusajishi District, where he awakened Shasha and discovered his Zanpakuto had a second, Hollow half named Ginhime. After testing his dual Shikai, Ten followed the scent of blood and encountered Kenpachi Zaraki naming the child Yachiru Kusajishi.

• Ten Unohana ignored Yoruichi's pleas, killed many residents of Zaraki District, and moved toward Kusajishi District as Yoruichi left to report to Mama Hana.
• Ten entered his Zanpakuto world, met Shasha and her Hollow counterpart, and named the blood-robed woman Ginhime.

• Ten followed the smell of blood to a field of corpses and overheard a man give the child beside him the name Yachiru and claim the title Kenpachi.
• Ten recognized the man as Kenpachi Zaraki and announced that he had waited a long time to meet him.

Ten abandoned his confrontation with Kenpachi Zaraki and returned to Retsu Unohana, then revealed his plan to target future captains. Yoruichi struggled with Ten’s actions, while Ten began seeking talented recruits in Rukongai and tried to keep his plans from drawing the Zero Division’s attention.

• Ten met Kenpachi Zaraki and Yachiru Kusajishi in Zaraki District, but left when Yoruichi called him back to the Seireitei.

• Yoruichi worried about Ten, and Retsu told her she would support him and that standing by him meant being prepared to oppose the world.
• Ten told Retsu he would return to Rukongai to recruit talented people, while intending to manage the captain succession without alerting the Zero Division.

Ten Unohana found the starving Rangiku Matsumoto in Rukongai and offered to take her in, using his Zanpakuto to remove her hunger and strengthen her. Rangiku agreed to follow him, though she struggled to remember his rules as they continued on together.

• Ten Unohana asked a frightened girl her name, and she introduced herself as Rangiku Matsumoto.
• Rangiku begged for food before Ten Unohana killed her, and he offered to spare her if she became his follower.
• Rangiku eagerly agreed, and Ten Unohana pressed his Zanpakuto to her stomach, transferring Reiatsu into her body.
• Rangiku realized she was no longer hungry, and Ten Unohana explained that his ability could eventually make her a Soul Reaper captain.
• Ten Unohana told Rangiku to obey his decisions and repeat his words, but she could not remember them all and nervously asked him not to hit her.

Ten brought Rangiku to live in the Seireitei, then enrolled at Shin'ō Academy and killed a man who challenged him. He told Retsu that his Zanpakuto had recovered and hinted that he was preparing a plan involving the captains, while keeping his dangerous circumstances from Yoruichi.

• Ten brought Rangiku to the Seireitei, where Retsu welcomed her and arranged for her to stay.
• Months later, Ten and Rangiku went to register at Shin'ō Academy, and Ten explained that he had to attend to honor Yamamoto.
• When a man grabbed Ten's clothes and refused to apologize, Ten killed him despite Yoruichi's protest.
• Ten told Retsu that his Zanpakuto had recovered and asked what would happen if he killed nearly half the captains.
• Retsu promised she would protect Ten even if it meant betraying Soul Society, and Ten said he had a follow-up plan.

• Ten introduced himself to Tessai Tsukabishi's class and shattered Tessai's Dankū with a single slash when a student challenged him.

• During Tessai's lesson, Ten dodged as Yoruichi and Hiyori Sarugaki crashed through the classroom wall and destroyed his seat.

• Ten Unohana caught Hiyori Sarugaki's Zanpakuto, snapped it, and sent a broken piece toward her before Kirio Hikifune's Kidō barrier deflected it into Hiyori's chest.

• Ten Unohana withdrew his Reiatsu, exchanged words with Kirio Hikifune, and left the damaged classroom using Shunpo, leaving Yoruichi behind.
• Ten Unohana told Retsu Unohana that he had fought Kirio Hikifune to prepare for his plan, and Retsu decided to start teaching him swordsmanship sooner.

Retsu Unohana began forging a personal swordsmanship style after Ten suggested that she combine and simplify the techniques she had learned. At Shin'ō Academy the next day, Ten was drawn into a group Kidō challenge from Shinji Hirako, Love Aikawa, and Rōjūrō Ōtoribashi.

• Retsu asked Ten why she had studied medicine and explained that she had pursued it to grow stronger after Kenpachi Zaraki defeated her.
• Ten suggested that Retsu combine the swordsmanship styles she knew into her own, and she left to develop the idea on an uninhabited mountain.
• Ten reflected that his plan would force him to leave Soul Society for Hueco Mundo and keep him separated from Retsu for at least a hundred years, but he resolved to proceed after Shin'ō Academy's future captains graduated.
• At the academy, Hiyori Sarugaki began attacking Ten with Kidō, but Yoruichi's spell interrupted her, and Ten expected Yoruichi to handle the fight.
• After Tessai Tsukabishi agreed to let the students practice Kidō, Shinji challenged Ten, with Love and Rōjūrō joining him.
• Ten accepted the challenge and told the three of them to attack him together.

Ten defeated Shinji Hirako, Love Aikawa, and Rōjūrō Ōtoribashi at Shin'ō Academy and warned the students not to provoke him as his long-planned scheme approached. Retsu completed her swordsmanship and planned to teach Ten and Rangiku, but Rangiku then revealed that her Zanpakuto had achieved Shikai.

• Ten overpowered Shinji Hirako, Love Aikawa, and Rōjūrō Ōtoribashi with Kidō, then warned the students that he would show no mercy if anyone troubled him again.

• Rangiku released Haineko and demonstrated that its dust blades could attack at Shunpo speed while she moved.

• Ten Unohana told Rangiku he would return to sleep instead of going to Shin'ō Academy.

• Isane Kotetsu found Ten Unohana injured, but he rushed back uphill to avoid having his training doubled and declined to stop for treatment.
• After Retsu Unohana healed Ten Unohana, Isane Kotetsu cautiously used healing Kidō on him while the swordsmanship training continued.

Ten Unohana began his captain slaughter plan by luring the Third Division Captain into a Space-Time Barrier and killing him with his Zanpakuto, which absorbed the captain’s strength. When a Tenth Division member exposed the attack and the Tenth Division Captain arrived, Ten Unohana killed the member and clashed with the captain, ending with both of them impaled and Ten Unohana’s body behaving like a phantom.

• After years of training with Retsu Unohana, Ten Unohana set his plan to kill the captains in motion.

• The Tenth Division Captain entered the barrier and attacked Ten Unohana, but Ten Unohana killed the member and impaled the captain with the Blade of Slaughter.
• The Tenth Division Captain’s Zanpakuto pierced Ten Unohana, but Ten Unohana’s body turned phantom-like as he drove the Blade of Slaughter deeper and caught the Poppy Scythe.

Ten used the Poppy Scythe to kill the Tenth Division Captain, then faced the Fifth Division Captain and the Captain of the Seventh Division together. He tricked them into misunderstanding his weapons’ abilities and killed both, but Soul Society had already been alerted to his attacks.

• Ten blocked the Fifth Division Captain’s long-range attack with the Poppy Scythe and watched the Tenth Division Captain dissolve after his power was drained.
• The Fifth Division Captain and the Captain of the Seventh Division entered Ten’s barrier and found his wound healed; the Captain of the Seventh Division released his Zanpakuto as a shield.
• Ten fought both captains and inferred that the Fifth Division Captain’s Zanpakuto could attack across great distances.
• The Fifth Division Captain concluded that the Poppy Scythe nullified attacks it touched, while Ten concealed the Blade of Slaughter’s absorption ability.
• Ten threw the Poppy Scythe and Blade of Slaughter using their adjustable connecting chain, striking both captains as they focused on dodging the weapons.
• The captains launched a final counterattack, but Ten nullified their attacks with the Poppy Scythe and watched them dissolve.

Ten Unohana escaped Soul Society after Shasha used the Space-Time Barrier to rescue his Zanpakuto, though he remained sealed and began to feel the influence of a Hollow. In Hueco Mundo, he emerged in Nel’s territory and warned her about Nnoitra before heading to the Forest of Menos to feed his growing bloodlust.

• Ten Unohana killed the Ninth Division Captain and the 11th Division Captain by absorbing them with his Zanpakuto, and Yamamoto arrived to confront him.
• Ten Unohana sent his Zanpakuto through the Space-Time Barrier, where Shasha activated it and escaped; Yamamoto sealed Ten Unohana, while Retsu Unohana watched in tears.
• Soul Society reported that Ten Unohana had killed six captains and was sealed in Muken, but Yamamoto prevented his execution because it would not kill him while his Zanpakuto remained free.
• In Hueco Mundo, Shasha and Ginhime freed Ten Unohana, whose Hollow mask appeared as the sealed part of his consciousness let the Hollow’s bloodlust affect him.
• Ten Unohana encountered Nel in her territory, warned her that Nnoitra would attack her and those around her, then left for the Forest of Menos to hunt Gillians.
