The plot is non-canon. The story opens in Karakura Town. A Shinigami was murdered, and all other Shinigami who were sent to investigate were murdered as well. Rukia is assigned to the mission, and she drags Ichigo along. Meanwhile, an incident known as the Red Moon (a literal coloring of the moon da a blood red hue) occurs. The Sixth Division Shinigami find out that it is protected da a force field. As they try to break it, a man interferes. He easily overpowers them. He then chants the phrase "Drink up", and the blood drains from the Shinigami into his sword. Renji comes at the last minute, but also starts to lose the fight. Rukia and Ichigo then appear, but they still could not stop the man (who reveals that his name is Iruma) even with Ichigo using his Hollow powers.
They return to Soul Society where the Tenth Division, and eventually, the Eighth Division and Thirteenth Division are assigned to deal with Iruma after the captains learn of what took place. They go back to the World of the Living and fight Iruma, but he manages to escape. During the fight, a small bird-like Hollow appears and seems to be holding Iruma back, but he shoos it away.
They return again to Soul Society where the the history of the sword is unveiled da Ukitake and Kyōraku. It was created da a scientist da merging a Zanpakutō with the powers of a Hollow. As it was a crime to do so, he was executed. Even then, the sword, Battou, continued to claim lives. It was successfully sealed, but the sword was able to break the foca, guarnizione da merging with it and then destroying it. As they finish the story, 10,000 Hollows suddenly appear in Karakura, and all available Shinigami were sent fight them off. Rukia and Ichigo fight Iruma yet again, however, Rukia dies after running to Ichigo's aid and getting stabbed da Iruma in the process. An intense battle ensues, but all Ichigo can do is mourn for Rukia.
The Red Moon suddenly liquefies and forcefully paves a path between Hueco Mundo and Soul Society using the blood obtained from the Shinigami. Iruma enters Soul Society via Senkaimon. It seems that he had baited all the Shinigami out of Soul Society through the Hollows so that he could enter unnoticed. Renji was left behind however, and starts fighting him off though he is still weak from their precedente encounter. Ichigo comes, and while they fight, Iruma states his history.
He had a high level of reiatsu as a human which allowed him to see and talk to ghosts. He loved a woman named Haruka, but she died in a fuoco that happened in the orphanage when he was out. He tried to cerca for her, but all he could see and hear were other ghosts. Battou started talking in his head that Haruka was in Soul Society, and the only way for him to reach it as a man was to pave a path through the Red Moon. Convinced of the plan, he started murdering Shinigami.
As they continue to fight, the bird-like Hollow appears and sides with Ichigo. Iruma cuts it down, and it is revealed to be Haruka. She tells him that she was trying to call out to him after her death, but he was blinded and deafened da grief. She was about to be turned into a Hollow mentally but she fought to keep her humanity at the cost of her words. She falls unconscious and Iruma loses his mind. He merges himself, Battou, and Haruka. Ichigo fought, but he had no chance of beating the monster. Byakuya appears and cuts Iruma with ease. Iruma is still alive but is in pain. This is because though he is separated from Battou, Haruka is still inside him as a Hollow, and combinations of man and Hollow cause unbearable pain to the human. Because of this, Haruka asks Ichigo to cut her out of him. He does so, and Iruma and Haruka talk again for the last time.
Ichigo then goes to the place where Rukia died with Sode no Shirayuki in his hand. He thanks her and says that he should have done this a long time ago. He hears Rukia's voice and thinks that he is hearing it in his head. However, Rukia stands, alive and well, as all the Shinigami who have died because of Battou are revived. She thanks him for crying over her death and is relieved that she could have someone like that. Ichigo tells her that he never wants to see that again. Finally, all the captains, lieutenants, and Shinigami gather together as the curtain draws.
