Rangiku regains consciousness, but is still giddy/does not have clear vision.
Gin gets slashed.
Aizen reminisces. Aizen says he was unable to solve the mystery of the Hougyoku before Urahara did.
In order to complete it, he had cut the souls from hundreds of Shinigami and souls in Rukongai and given them to the Hougyoku, but it hadn't been satisfied with that.
Aizen thought that the Hougyoku Urahara had was completed, so Aizen tried to obtain it and give it to his Hougyoku and the flashback ends here.
Gin reaches out for the Hougyoku even after being slashed. Aizen grabs him by the wrist and hauls him up. Once again, he stabs Gin with his sword.
Aizen says that for progress, there must be fear, and that thanks to Gin, he was able to become a higher being
Gin gets hurled in front of Tatsuki and the rest, and Rangiku is en route there. Tatsuki and Kanonji have been battered by the reiatsu and have become weak, so they collapse.
Flashback
In the snow, when they were young, Rangiku drops in on Gin, who has returned wearing the Shinigami garb.
Gin says that he'll become a Shinigami and change for Rangiku, and he'll get it done such that Rangiku wouldn't cry. There is blood on his cheek.
Flashback ends, Rangiku approaches Gin, screaming
Gin says that in the end, he wasn't able to recover the things that were taken from Rangiku and that he'd best apologise.
Rangiku, realising that Gin is dying, cries uncontrollably. Aizen appears behind her.
There are loud foot steps approaching and when Aizen turns around it's Ichigo hefting Isshin on his shoulders.
