Output: In the Soul Society, Soul Reapera scientist Mayuri Kurotsuchi is attacked in his laboratory by a pair of mysterious siblings wielding a scythe that erases his memories. In a frightened panic, Kurotsuchi damages one of his machines, causing a massive spirit energy explosion that covers much of Soul Society, killing or freezing many Soul Reapers. Rukia Kuchiki is the next to be attacked by the siblings, erasing her memories and those of everybody that has memories of her, and is carried away to Soul Societys Rukon District by the siblings. In the real world, one of Rukias friends, Ichigo Kurosaki, briefly forgets her but Kon, being a modified soul, is unaffected by the memory wipe and reminds himm. Ichigo and Kon go to former Soul Reaper Kisuke Urahara for information; but Urahara does not remember Rukia. Ichigo and Kon travel to the Soul Society with all the captains unable to remember Ichigo, believing him to be a threat. Meanwhile, Rukia wakes up in the Rukon District with no memory of being a Soul Reaper. The nameless siblings, a sister and a brother, remind Rukia that they used to be close friends living together and she was to give them names, although she has forgotten them. Ichigo seeks the help of Rukias adopted brother, Byakuya, but he does not remember Rukia either. After another confronting with Renji Abarai, Rukias chilhood friend, Byakuya directs Ichigo to his wife, Hisanas, birthplace, where they are briefly reunited with Rukia before the siblings flee with her from Ichigo and Kon. Ichigo and Kon are attacked again by other Soul Reapers, but are saved by Renji Abarai, who follows his instinct to trust Ichigo. When Soul Societys headcaptain and other captains arrive to capture Ichigo, Urahara interferes. He sends Ichigo, Renji and Kon off to save Rukia, and explains to the captains that he studied a parasitic Hollow which could erase memories with its scythelike tentacle, but it escaped and appears to be influencing the siblings actions to an extent. Meanwhile, the siblings go to Kurotsuchis laboratory to fully destroy the Soul Reapers with another spiritual machine of Kurotsuchis, under the belief that the Soul Reapers were responsible for taking Rukia away from them when they were younger. Rukia suddenly objects to this, and Ichigo and Renjis arrival prompts her to remember them and her entire past, with both the siblings and her time as a Soul Reaper. The female sibling succumbs to rage, and she forces herself, her brother and Rukia to all fuse into one, creating Dark Rukia. Dark Rukia, seemingly hollowified, unleashes the machine upon Soul Society before battling Ichigo. The machine takes the form of a monster, and the Soul Reapers fight against it. Ichigo fights Dark Rukia and holds back initially to refrain from injuring her. Byakuya arrives and claims that he should be the one to finish this, but Ichigo intervenes and manages to free her with his own similar spirit energy, destroying the Hollow; Byakuya and Renji also destroy the monster. Rukia regains her memories, but the siblings are left mortally wounded, though they are regretful for their actions. Urahara arrives and explains that the Hollow attacked Rukia and the siblings while controlling a Soul Reapers body previously, but when the body was destroyed, the siblings trapped the Hollow in their bodies and were sent to Hueco Mundo—the Hollows world—for a time, managing to escape to reunite with Rukia because of their desire to be with her. Rukia tells the siblings their names, Homura and Shizuku, but the two die from their wounds, much to Rukias despair. Later, Ichigo asks Rukia at the hill shrine where she previously visited before, about the shrines were made in remembrance of her childhood friends who died during adolescence due to poverty, reminding her that her memories of the siblings will not fade.
