Tōjū Campaign

The Tōjū Campaign is an event in which berserker swords materialise 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.
