Tōjū Campaign

The Tōjū Campaign is an event in which berserk Zanpakutō spirits run rampant all across Seireitei in the wake of Muramasa's Rebellion, threatening to disrupt the peace brought after the conflict was resolved. These so-called "Tōjū" were released as a direct result of Muramasa's abilities, and as such are in a constant Bankai state. The last remaining Tōjū, Kirikaze, gained the ability to absorb reiryoku, threatening the existence of the Zanpakutō spirits.

The campaign began when Byakuya Kuchiki held a party for his subordinates at the Manor, whereupon Rukia encountered the first Tōjū. After this event, Mayuri Kurotsuchi became aware of this new development, and the Tōjū were progressively hunted down and killed by the Shinigami.

The event ended after the final Tōjū, Kirikaze, encounters the Zanpakutō Spirits, who attempt to defeat him without the assistance of their Shinigami masters. As they fight him, the Shinigami intervene, teaming up with their respective spirits, promptly defeating the last Tōjū with the assistance of Renji Abarai's Bankai. With the peace restored and the Zanpakutō returned to their rightful place, the Shinigami return to Seireitei.

Prelude
At the Kuchiki Manor, Byakuya Kuchiki and his division members relax after the prior conflict. As Renji Abarai and Rukia Kuchiki contemplate the damage to Seireitei, he is pulled away by another Shinigami. Rukia wanders around the manor by herself, as she hears a ruckus ensuing in one of the serving rooms. She enters the room, observing two figures attacking. Rukia calls to their attention, as she faces off against them unarmed. However, Sode no Shirayuki and Senbonzakura intervene, cutting down one of the figures. The group then head to the Shinigami Research and Development Institute, whereupon Mayuri Kurotsuchi elaborates upon the existence of Tōjū. Rukia and the Zanpakutō spirits formulate a plan to capture the missing Tōjū, resulting in them holding a party in the 10th Division's barracks.

After the party concludes, their plan fails, prompting Sode no Shirayuki to impart her feelings to Rukia. Suddenly, the missing Tōjū appears on the scene, as the two move to capture him. As they fight against the Tōjū, his constant Bankai state makes it difficult for them to defeat him, but is eventually subdued once Rukia calls Sode no Shirayuki back to her katana. After their conflict, Rukia reports the existence of the Tōjū to her captain, as Jūshirō Ukitake states that their time of peace was short-lived. The next day, in the Human World, a Tōjū crashes down from the sky. He is confronted by Ichigo Kurosaki and Tōshirō Hitsugaya, who briefly clash with him. However, the two are unable to stop him from escaping, leaving Ichigo surprised by the Tōjū's words.

They arrive at the Urahara Shop, where they inform Kisuke Urahara that a new species has resurfaced. Hitsugaya informs Ichigo about the existence of the Tōjū, proclaiming them to be highly volatile and dangerous. He states that the Soul Society is unsure of how many exist, which Ichigo states isn't helping their situation. Meanwhile, the Tōjū wanders in a dark alleyway, and is met with a Hollow, which proceeds to consume him. Hitsugaya and his Zanpakutō notice the displacement in reiatsu, as Nanao Ise successfully persuades Mayuri to research the Tōjū phenomena. Rangiku, Haineko and Orihime are walking through Karakura Town, when the Tōjū appears before them atop a construction facility. It attacks them, resulting in Ichigo's intervention. As they take their fight elsewhere, Zangetsu tells Ichigo that this was the Tōjū which they fought earlier, theorizing that it has merged with a Hollow. The Tōjū fires a Cero at Ichigo, as Hitsugaya uses this as a diversion, freezing it in ice. Afterwards, Hitsugaya imparts a piece of advice to them, stating that they shouldn't underestimate a Tōjū's strength.

Early Stages
Renji Abarai and Zabimaru arrive in the Human World, as he warns them not to get distracted. Renji informs them that their only objective is to eliminate the Tōjū, leaving Snakey behind. As Renji and Chimpette face off against the Boomerang Tōjū, he is forced to retreat from them. They lure him to Snakey's location, but their trap ultimately fails when Snakey is distracted by a fish. Chimpette berates her lower half, as they move out in search for him. Snakey comes across the Tōjū once more, letting him go on a whim that it will bring him freedom. He then leaves the company of Renji and Chimpette, in an attempt to do as he pleases. However, Karin Kurosaki stops him from stealing food, eventually resulting in Snakey being invited to stay at their house. Chimpette contemplates that Snakey's actions mimic those of the Tōjū, as the two sisters try to entertain Snakey. He is forced awake by Ichigo, and storms out of the house, where he meets up with the Tōjū. He asks whether Snakey received his freedom, as he attempts to fight the Tōjū. However, Karin appears, and is used as a shield by the Tōjū, forcing Snakey to drop his weapon. The Tōjū proceeds to beat Snakey up, as Renji and Chimpette arrive on the scene, finishing the Tōjū off. Later, Snakey returns an unconscious Karin back to Ichigo, before returning back to Soul Society.

Back in Soul Society, various items across Seireitei have started to disappear, originating with the disappearance of Hanatarō Yamada's chickens. In response to this, Captains Kyōraku and Ukitake send a taskforce consisting of Ikkaku Madarame, Hōzukimaru, Nanao Ise and Hanatarō Yamada into the underground waterways to find the culprit responsible. The captains relay their suspicions that the perpetrator might be a Tōjū, as the group make their way through the catacombs. Hanatarō comments that there are ghosts of dead people living here, which Nanao Ise refutes. Hanatarō reassures her, as he trips on a thin wire, resulting in an explosion. Nanao tells them to remain alert, as Ikkaku comes across another trap, which Hanatarō attempts to sidestep. However, this results in an enormous tidal wave hurtling after them, washing them up in a farther section of the waterways. As they regain their bearings, an enormous form moves towards them, pulling Ikkaku under the water.

Hanatarō believes it to be a joke, as several tentacles emerge from the water, constricting the Shinigami. They are pushed away, as the Tōjū makes off with Ikkaku. Hōzukimaru reassures a guilt-stricken Hanatarō, stating that Ikkaku is still alive. As they proceed through the tunnels, they come across a campsite, in which all of the stolen items are present. The culprit appears before them, promptly interrogated by Hōzukimaru and Nanao. However, the Tōjū hurls Ikkaku across the floor, as Hōzukimaru fights the Tōjū with his Bankai. He is unable to attack due to the Tōjū's slimy skin, and is thrown across the water. The culprit responds by healing Ikkaku's injuries using a sword, and promptly conjures up a cannon from his mid-section, incinerating the Tōjū. As they report back to the captains, Nanao informs her captain that Hisagomaru was responsible, mainly due to the fact that he began a solitary life in the waterways. Kyōraku asks where the individual in question is, as Hanatarō explains that they became separated on the journey back.

The next day, a group of Shinigami consisting of Lieutenant Shūhei Hisagi, Ikkaku Madarame, Tetsuzaemon Iba and Izuru Kira investigate a district of Rukongai which has come under attack by numerous Tōjū. As they make their way towards the district, Kazeshini attacks them, forcing Shūhei to face off against his Zanpakutō, whilst the others go on ahead. Kazeshini states that he will continue until the two of them finish their earlier fight. As Shūhei fights against his Zanpakutō, they reveal what they dislike about each other, resulting in Kazeshini's defeat. Shūhei informs his Zanpakutō that he will not fight against him until he fights fairly. As he regroups with the others, Shūhei is informed that the Tōjū fled before they could encounter them. As Kazeshini returns back to the other Zanpakutō, they berate him for straining relations with the Shinigami. Later, the Tōjū begin to attack Rukongai once again, as Shūhei intervenes to protect the civilians. However, Kazeshini appears before them, and Shūhei protects the civilians from his Zanpakutō's attacks, proceeding to knock him into a nearby building.

As Kazeshini lies within the rubble, he wonders why Shūhei tries to help others. As Kazeshini searches for Shūhei, he comes across the Tōjū, promptly cutting it down with ease. Before he can leave, the Tōjū's victim tells him to protect his child. Kazeshini is forced to take the child with him, to prevent it from attracting attention. The bond between the child and Kazeshini grows, rendering him unable to abandon it. The other Zanpakutō mock him, as the lieutenants get word of Kazeshini's "child". He leaves the child in a nearby hut, in order to fight against Shūhei and the others. However, he is forced to return to the hut, finding a woman trying to soothe the child. As it cuddles next to his leg, much to the woman's surprise, a Tōjū emerges from behind. Kazeshini protects the child with his own body, before cutting the Tōjū down. He instructs the woman to take the child away, as he approaches Shūhei for the last time. As they fight, Shūhei inquires of the child, but Kazeshini denies knowing what he is talking about. However, Kazeshini is defeated due to the injury he sustained whilst protecting the child. He tells the child not to cry, falling defeated to the ground. Shūhei reassures him, stating that they will fight to protect others, as Kazeshini half-heartedly says that he won't like that.

Middle Stages
A Tōjū wails in pain, inquiring why her master has neglected her, as a bright light envelops her. Back in Karakura Town, rumours are travelling through Karakura High School of a "phantom attacker" whom preys upon high school students. Their teacher arrives in the classroom, announcing that they have a new student, Kyōko Haida, as Kisuke Urahara informs Ichigo of the recent spate of attackings involving high school girls, stating that a pink bear was found at the scene. As Orihime Inoue learns more about the new arrival, another girl flees from the attacker, who is wielding a Zanpakutō. As the police arrive, Ichigo overlooks the scene, noticing that a pink bear hanging on the girl's cellphone. The next day, Kyōko is injured whilst playing sport, and Orihime volunteers to assist her, eventually utilising her powers to save her from a falling object. She proclaims that she too has special powers, prompting her to reveal her traumatic past. However, Kyōko collapses to the ground, as the Tōjū takes control of her body, fleeing from the scene.



She proclaims that she too has special powers, prompting her to reveal her traumatic past. However, Kyōko collapses to the ground, as the Tōjū takes control of her body, fleeing from the scene. The Tōjū berates Kyōko upon her stupidity, claiming that she saved her from making the same mistake twice. It takes control over her body once more, telling her that she will fulfill her hatred for her friend. Orihime runs to the scene, as Mai Suzuki is being pursued by Kyōko. She stops before she can deal the finishing blow, regaining control over her body. However, Mai refuses to listen to her former friend, prompting the Tōjū to fuse with her body, as Orihime arrives on the scene. The Tōjū attacks her with her blades, as Ichigo and Rukia intervene. Ichigo proceeds to fight the Tōjū, commenting that Kyōko's presence is barely discernible. Rukia tells him that they may have no choice but to kill her, prompting Orihime to protest. As the Tōjū begins to scream in pain, Orihime uses Sōten Kisshun upon it, expunging Kyōko from its influence, resulting in its imminent death by the hands of Ichigo. Kyōko and Orihime then become good friends.



Back in Soul Society, a group of Shinigami led by Rangiku Matsumoto search for the Tōjū within the mountains. Haineko splits up from the Shinigami, promptly sparing a Tōjū's life. She keeps this secret from her Shinigami, to prevent him from being immediately killed. Haineko returns back to the house where she is keeping the Tōjū, Narunosuke, and tends to his injuries. Narunosuke reveals more about his past, stating that his cowardly nature came from his Shinigami. He asks Haineko to try and persuade the Shinigami of his good nature, as she appears before Rangiku. The Shinigami states that that request is impossible, and given enough time, a Tōjū will eventually lose control. She returns back to the house, as Narunosuke begins to have a migraine once more, telling him to get some rest. As Haineko leaves his presence, he experiences another migraine, stating that he cannot sense any feeling in his hands.The next day, Haineko returns to Narunosuke, who is immersed in purple reiatsu.



The next day, Haineko returns to Narunosuke, who is immersed in purple reiatsu. She reveals to him that the Shinigami refuse to let him live, as he attempts to flee from the Shinigami. As Haineko prevents him from leaving, he loses control, lashing out violently. She realises that Rangiku's statement has come true, as Tōshirō Hitsugaya reveals to his lieutenant that various medical supplies have gone missing, prompting her to analyse the situation with Haineko. She denies any involvement when confronted by Rangiku, and instantly returns to an agony-stricken Narunosuke. Rangiku arrives onto the scene, berating her Zanpakutō spirit for concealing him, as Narunosuke undergoes a transformation. As Rangiku prepares to kill the Tōjū, she is surprised that Haineko is still defending him. She is forced to fight against both Haineko and Narunosuke, who realises that he is beyond help, encircling them both within her Shikai. Narunosuke regains his sanity for a moment; thanking Haineko for her help. Rangiku and Haineko sit and watch the sunrise, the Shinigami consoling her Zanpakutō spirit.



Later, Chimpette and Snakey face off against a Hammer Tōjū, but find themselves trapped under a mound of dirt. The Tōjū is eventually killed by the likes of Senbonzakura, who berates them for letting their guard down. They are angered by the 6th Division 's unwavering praise of Senbonzakura's abilities, and leave to hand the Tōjū over to the Shinigami Research and Development Institute. However, no-one is there, due to the fact that the officers are out engaging in field research. As they attempt to break into the institute, Senbonzakura appears, stating that he was given a similar goal. Snakey and Chimpette then realise that Senbonzakura is nothing like what his peers believe him to be. As they enter a chamber filled with Tōjū, the trio place the katana into a glass chamber, which results in their entrapment by Senbonzakura. As Senbonzakura tries to break out from the chamber, Snakey and Chimpette state that the glass is reinforced to resist a Tōjū's powers. However, they are interrupted by Ashisogi Jizō, whom they attempt to signal. It is confused by their initial actions, but eventually picks up the remote control sealing them in.



However, due to Senbonzakura's impatience, the Zanpakutō spirit shatters it into pieces, as he resorts to the use of his Bankai, which destroys the chamber. They are alerted by an alarm ringing out, as the blast doors proceed to seal them in, resulting in their arrival at the main control room. As Senbonzakura helms the controls, he inadvertently causes disaster to erupt across Seireitei, resulting in a conflict ensuing between the three Zanpakutō spirits in Bankai. As a consequence of their fight, the Shinigami Research and Development Institute is destroyed, as Snakey and Chimpette are held responsible. They try to pin the blame on Senbonzakura, who explains that each of his actions had a logical explanation behind them. Snakey and Chimpette are given several piles of paperwork to fill out as a result, but when they hear Senbonzakura is in charge of a new Tōjū mission, they drop everything and pursue him. Mayuri Kurotsuchi and his subordinates arrive at the remains of the S.R.D.I., who is less than pleased with what has occurred.

End Stages
On the 8th Division grounds, Shunsui Kyōraku and his Zanpakutō spirits relax under the shade of the blossoms. As his lieutenant, Nanao Ise approaches her, he assigns her the task of dealing with a Tōjū alongside his wakizashi. As the pair encounter the Bearded Tōjū, the wakizashi proceeds to torture him, prompting Nanao to intervene, allowing the Tōjū to make its escape. After the incident, Nanao seeks the assistance of Rangiku Matsumoto, who tries to persuade the taciturn Zanpakutō spirit to open up, to no avail. In response to this, Nanao attempts to hold a party with her captain, eventually following the wakizashi to the barren trees. She fixes a single flower into the wakizashi's hair, taking her to an area filled with flowers. Nanao tells the wakizashi to lay down her weapon, as the Tōjū makes its untimely appearance, forcing her onto the ground. As the wakizashi faces off against the Bearded Tōjū, her flower is cut into pieces. Nanao intervenes as the Tōjū prepares to finish her off, with the Tōjū stating that he has no choice but to kill her as well. However, the Tōjū is approached by Shunsui Kyōraku, who cuts the Tōjū down instantly. The Shinigami and the Zanpakutō spirits then enjoy the party, as Rangiku is surprised that Nanao was able to open the wakizashi's reclusive heart.

Later, Kazeshini and Shūhei Hisagi hunt down a Tōjū in Seireitei, as the berserker sword disintegrates before Kazeshini's eyes. As Renji Abarai and Shūhei Hisagi confer upon the dwindling numbers of the Tōjū, their Zanpakutō get into an argument. Later at night, another Tōjū is preyed upon, as Kazeshini and Zabimaru approach Hōzukimaru and Ruri’iro Kujaku. Kazeshini informs the two spirits that he was able to find the Tōjū they are searching for, as the Zanpakutō spirits resolve themselves to defeat this last Tōjū and thus eradicate them from existence. The Zanpakutō spirits are notified of its whereabouts, appearing before it the following day. Kazeshini realises that the Tōjū is in fact Kirikaze, explaining to the others who Kirikaze is, stating that he despised his master. Hōzukimaru and the others prepare to attack Kirikaze, but experience difficulties due to its ability to phase into mist. However, they gain an advantage once Ruri'iro Kujaku uses his vines upon the Tōjū, proceeding to drain its reiryoku.

This success does not last long, as Ruri'iro Kujaku begins to cringe, and it becomes clear that Kirikaze is draining the Zanpakutō spirit's reiryoku, as his form begins to fluctuate. The technique is halted by Kazeshini, who slices the vines with his Shikai. The Zanpakutō spirits begin to fight him again, despite their reiryoku levels running low, and it is certain that they are fighting a losing battle. However, the Shinigami arrive to assist them, much to their surprise. Izuru Kira binds the Tōjū with Sajo Sabaku, stating that it can no longer dissipate into mist. They realise that Shinigami and Zanpakutō are meant to work together, fighting alongside one another in order to defeat the Tōjū. As the joint team fights against Kirikaze, he begins to run away from them, as Renji realises that he cannot revert back to his mist state. The Zanpakutō pool their remaining reiryoku into Renji Abarai, who finishes off the Tōjū with an enhanced Hikotsu Taihō.

Aftermath


When the Zanpakutō spirits return back to their swords, Nanao Ise contemplates the emptiness they feel once they are gone. However, Izuru Kira states that their materialised forms were never meant to be, and that their true forms lie within their katana. Rangiku reassures her, explaining that they are now back to where they belong. Momo states that she can sense Tobiume's presence emanating from her sword, proclaiming that they will be together forever. The crisis ended, the Shinigami return back to Seireitei.
