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 scythe-like tentacle, but it escaped and appears to be influencing the siblings' actions to an extent. When Soul Society's head-captain and other captains arrive to capture Ichigo, Urahara interferes. Ichigo and Kon are attacked again by other Soul Reapers, but are saved by Renji Abarai, who follows his instinct to trust Ichigo.

After another confronting with Renji Abarai, Rukia's childhood friend, Byakuya directs Ichigo to his wife, Hisana's, birthplace, where they are briefly reunited with Rukia before the siblings flee with her from Ichigo and Kon.

Ichigo seeks the help of Rukia's adopted brother, Byakuya, but he does not remember Rukia either. 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. Meanwhile, Rukia wakes up in the Rukon District with no memory of being a Soul Reaper. Ichigo and Kon travel to the Soul Society with all the captains unable to remember Ichigo, believing him to be a threat. Ichigo and Kon go to former Soul Reaper Kisuke Urahara for information but Urahara does not remember Rukia. In the real world, one of Rukia's friends, Ichigo Kurosaki, briefly forgets her but Kon, being a modified soul, is unaffected by the memory wipe and reminds him. 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 Society's Rukon District by the siblings.

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. In the Soul Society, Soul Reaper scientist Mayuri Kurotsuchi is attacked in his laboratory by a pair of mysterious siblings wielding a scythe that erases his memories.
