Chapter Summaries

Tsuna and his allies fought Sojiro Kusaka, who impersonated Toshiro with a counterfeit Hyōrinmaru and used the King's Seal to overpower them. Kusaka escaped to Soul Society, and Tsuna left to ask the Captain-Commander about the seal and its powers.

• A masked man attacked Tsuna and the others with a purple ice dragon, while two Arrancar fled to his side.
• Tsuna recognized the man as Sojiro Kusaka and shattered his ice dragon, then pursued him as Ichigo and Uryū held off the Arrancar.

• Tsuna told Ichigo and Uryū to return to school and departed for Soul Society to question the Captain-Commander.

Tsuna asked Yamamoto about the King's Seal and learned it was meant to stabilize the western Soul Society, while the Soul King Palace ordered its recovery. He then worked with Urahara to prepare an artificial blade that might address the shortcomings of Toshiro’s Hyōrinmaru, leaving Yamamoto convinced that Tsuna trusted Toshiro’s future.

• Tsuna gave Yamamoto Toshiro’s letter, and Yamamoto revoked the arrest order and confinement of the 10th Division while assigning Rangiku to manage it.

• Tsuna proposed using the artificial blade and Sojiro Kusaka’s sword to make up for the power Hyōrinmaru had divided between Toshiro and Kusaka.
• Tsuna said Toshiro deserved the Soul Society’s trust, and Yamamoto believed Tsuna could become the Soul Society’s future leader.

• Tsuna predicted Tokinada might kill the clan in a staged accident and suggested luring Kusaka into its grounds.
• Unohana entered the ward and ordered Kyōraku back to work, so Kyōraku escaped with Nanao while Tsuna was left behind.

• Toshiro tried to finish Kusaka with the hollow Zanpakuto, but the Arrancar sisters interrupted him as Kusaka revealed his plan to take Toshiro's Hyōrinmaru.
• Kusaka broke the King's Seal and transformed into Purple Maru, a humanoid ice dragon whose power shattered Toshiro's ice attack and sent him flying.

Toshiro and the Captains fought to reach Purple Maru while his ice world froze the Bleach and unleashed Hollows against them. Tsuna turned himself into an artificial sun to warm and empower the defenders, but after Sajin Komamura struck Purple Maru into Sokyoku Hill, the other Captains kept Tsuna from pursuing him.

• Toshiro struggled to break through the ice monsters until Renji Abarai used Higa Zekkou to open a path toward Sokyoku Hill, and Rangiku led the Vice-Captains in protecting it.

• Tsuna tried to pursue Purple Maru, but Hirako and the other Captains pulled him back into their protective formation.

Purple Maru used the King's Seal to trap fighters inside a barrier, but Tsuna and the captains fought their way toward the tower. Toshiro weakened Purple Maru with a hidden ice technique and prepared to strike Sojiro with the blade that had ended their past battle.

• Purple Maru raised a King's Seal barrier that isolated Yamamoto, while Tsuna remained inside and Byakuya ordered the trapped Bleach to defend themselves.
• Tsuna, Toshiro, and Renji charged up Sokyoku Hill as Purple Maru summoned Gillian and sent two empowered Arrancar to stop them.

• Toshiro attacked Purple Maru with repeated slashes that secretly planted Hyōten Hyakkasō ice flowers, which spread through Purple Maru's body and shattered his ice armor.
• Toshiro saw Sojiro's exposed left chest, steadied his trembling hand, and drew his empty-shell Zanpakuto to repeat the decisive strike from their past battle.

• Tsuna watched Sojiro Kusaka's body crumble and exposed the purple Hyōrinmaru consciousness's attempt to lure Toshiro into danger.
• The purple Hyōrinmaru consciousness sent the King's Seal into a spatial rampage, expanding a black hole through the barrier enclosing the world of ice.
• Tsuna ignited the Sun Armlet and struck the black hole with Ultimate Blazing Sun, forcing it to shrink and leaving the King's Seal on course for destruction.

Tsuna helped restore order after the King's Seal's power vanished, while Toshiro wielded two Hyōrinmarus and accepted his place in the Gotei 13. Later, Tsuna and Urahara investigated a Bleach killed by his own wind blade and set out for Rukongai to find someone they believed had emerged.

• Kenpachi's slash damaged Sokyoku Hill, so Byakuya asked Toshiro to freeze the fractured section and stabilize it.
• Toshiro used both Hyōrinmarus to cover the damaged area in ice and vowed to master their power in honor of its former wielder.
• Yamamoto told Toshiro to report to Squad 1 wearing his captain's haori, confirming his return to the Gotei 13.
• Urahara told Tsuna that a Bleach in Rukongai had died from wounds resembling cuts made by his own Wind Style Zanpakuto.
• Tsuna and Urahara went to Yamamoto for permission to travel to Rukongai and pursue the suspected emergence.

Tsuna and Urahara tracked Muramasa to a remote district of Rukongai, where they fought his blade beasts and Muramasa attacked Urahara’s Zanpakuto. After Muramasa entered Tsuna’s inner world to influence his Zanpakuto, Tsuna followed him in, ready to confront him there.

• Tsuna and Urahara searched the desolate hillside where a Bleach had been found and encountered a group of blade beasts.

• Muramasa followed Tsuna into the school, which transformed into a moonlit castle within Tsuna’s inner world.
• Muramasa tried to recruit Decimo with promises of freedom, but Decimo dismissed his claims and Byakuran mocked him.

Muramasa brought Red Princess into the Soul Society to escape Tsuna, but Tsuna restrained him while Red Princess confronted Urahara over the scars he had given her through his modifications. As Red Princess turned violent and Urahara struggled to defend himself, Tsuna sent Yoruichi the pair’s location and waited to see what would happen.

• Muramasa tried to sway Urahara, and Tsuna returned and kicked him before discovering Red Princess clinging to Urahara.
• Tsuna bound Muramasa with Arnold's Handcuffs and moved away as Red Princess confronted Urahara.
• Red Princess showed Urahara the scars from his modifications and threatened to carve similar marks into him.
• Tsuna asked Muramasa why Red Princess was obsessive, and Muramasa said he had only amplified her dissatisfaction with her master.
• Tsuna suggested Muramasa's own master might one day no longer need him, then sealed his mouth again.
• Tsuna photographed Urahara and Red Princess, sent the image and their location to Yoruichi, and watched as Urahara struggled to fight Red Princess.

Urahara fought Red Princess after she turned the powers of his Zanpakuto against him, while Tsuna watched and delayed helping. Yoruichi arrived and exposed Red Princess's Bankai weakness, giving Urahara the chance to defeat her and leave her in Shikai form.

• Urahara dodged Red Princess's attacks and used a portable gigai to escape her Razor Red Princess strike, while Tsuna refused to help and said Yoruichi was coming.
• Red Princess unleashed Bankai, Kannonbiraki Benihime, and modified the ground to keep Urahara close and prevent Tsuna from intervening.
• Yoruichi arrived, freed Urahara from the tower Red Princess had created, and evaded Red Princess's attacks by using her speed.
• Yoruichi kicked Red Princess into the ground, and Urahara completed Hadō 91: Senju Kōten Taihō, leaving Red Princess in her Shikai form.

• Urahara transformed Red Princess into her human form, while Yoruichi and Tsuna teased him about his new Zanpakuto and shared an embarrassing picture of him.
• Tsuna promised Muramasa he would take him to Kyōka Kutsuki, then brought him to Yamamoto in the Seireitei.
• Yamamoto arranged for Byakuya to join the group, and Yoruichi returned to the World of the Living with Koume to prepare for the encounter.
• At a lake in Karakura Town, Tsuna released Muramasa's restraints, and Muramasa broke the seal on Kyōka Kutsuki's coffin.
• Kyōka Kutsuki emerged from the coffin, intent on destroying his enemies, and decided to kill Muramasa first.

Muramasa learned that Kyōka Kutsuki had hated him for supposedly abandoning him and was shattered when Kyōka broke his Zanpakuto body. As Muramasa’s Hollow power erupted, Tsuna persuaded him to accept a new master, leaving him ready for Tsuna and Urahara’s plan to use him for Blade Zen.

• Kyōka Kutsuki stabbed Muramasa and accused him of failing to answer when Kyōka called for him before being sealed.
• Kyōka broke Muramasa’s true Zanpakuto body, while Tsuna and Urahara watched and Yamamoto ordered Byakuya to handle Kyōka.
• Byakuya attacked Kyōka and drove him away, while Urahara cut off Muramasa’s connection to Hueco Mundo and he and Yoruichi eliminated the Hollows emerging from Muramasa.
• Tsuna asked Muramasa whether he regretted choosing Kyōka, then offered him the chance to have a caring new master.
• Muramasa accepted Tsuna’s offer and gave up resisting, unaware that Tsuna and Urahara planned to use him for Blade Zen.

Tsuna used his Rain techniques to cleanse Muramasa of Kyōka Kutsuki’s influence and began preparing a new Zanpakuto for him. Genryūsai Shigekuni Yamamoto questioned whether the method could be used to take other Zanpakuto, and Tsuna explained its limits as Yamamoto identified Koume as Muramasa’s prospective master.

• Tsuna explained to Genryūsai Shigekuni Yamamoto that the method required specific conditions and could not mass-produce Zanpakuto.
• Genryūsai Shigekuni Yamamoto recognized Koume as the child intended to become Muramasa’s new master.

Tsuna used his Sky Flame to forge a new Zanpakuto by harmonizing Muramasa’s power with Urahara’s replicated blade. Koume awakened Muramasa as her Zanpakuto spirit and welcomed him as a friend, bringing color to her inner world.

• Yamamoto decided Koume would join the new organization, while Muramasa’s form faded as his power was absorbed into the hollow Zanpakuto.
• Tsuna surrounded the Zanpakuto with Sky Flame and spent days forging it as Ichigo and the others waited by the lake.

• Urahara gave the Zanpakuto to Koume, who entered her inner world and called Muramasa by name.
• Muramasa recognized Koume as his new master, but Koume asked him to be her friend, and color began to fill her inner world.

Koume mastered Muramasa’s power, and Tsuna prepared to begin a new phase of training in the Soul Society by having Bleaches materialize their Zanpakuto spirits. Squad 1 ordered all participants to gather the next day, leaving Tsuna ready to start with the Vice-Captains.

• Koume’s Asauchi changed into Muramasa, who acknowledged her as his master, and Urahara asked Yamamoto for time to help her adapt to his power.
• After recovering at home, Tsuna visited the Urahara Shop with Tatsuki, comforted Jinta, and watched Koume and Muramasa train against Ichigo.
• Tsuna told Urahara he would first settle matters in the Soul Society, then planned to use Muramasa to help Ichigo train and asked Koume to join the next training phase.
• Tsuna took Koume to Squad 1, where Yamamoto approved her progress and issued an order requiring every Bleach in intensive training to gather the next day.
• Ikkaku and Yumichika discussed the change to training and noted how much the Bleaches’ strength and Zanpakuto had improved.

Tsuna introduced advanced Blade Zen training, using Koume and Muramasa to materialize Bleach’s Zanpakuto spirits so their wielders could meet them directly. The training left Rukia reunited with Sode no Shirayuki and Shūhei fighting Kazeshini, while Tsuna prepared to let each person train with their Zanpakuto individually.

• Shūhei learned that Shiba had missed training because he was trying to make his Zanpakuto submit and achieve Bankai.
• Tsuna introduced Koume as the temporary instructor and explained that Muramasa could materialize Zanpakuto spirits.
• Koume summoned Sode no Shirayuki, who appeared before Rukia and explained why the new training would let them speak face-to-face.
• Tsuna explained that materialized Zanpakuto spirits took their wielders’ Shikai powers, which could be reclaimed by defeating the spirit or earning its recognition.
• Muramasa summoned Kazeshini, who immediately attacked Shūhei, and the two began fighting.

Tsuna oversaw the training camp members as they met their materialized Zanpakuto, then discovered that Hanatarō’s Hisagomaru had already made Bankai available to him but withheld it because Hanatarō’s spiritual pressure was too low. Tsuna arranged for Captain Unohana to train Hanatarō’s spiritual pressure, leaving Hanatarō anxious about putting healing Kido aside.

• Ikkaku and Hozukimaru bonded over fighting, while Yumichika argued with Ruri'iro Kujaku about the Zanpakuto’s old name.
• Rukia took Sode no Shirayuki home, Ōmaeda left with Gegetsuburi, and Rangiku teased Tsuna about materializing Hyōrinmaru before taking Haineko away.
• Tsuna advised Izuru and Wabisuke to return to the 3rd Division together, then let Isane take the mischievous Itegumo back to Squad 4.
• Tsuna learned that Hisagomaru was satisfied with Hanatarō and had kept Bankai’s name from him until his spiritual pressure became sufficient.
• Tsuna arranged for Unohana to train Hanatarō’s spiritual pressure and told him to stop healing Kido until he met Hisagomaru’s requirements.
