[taken from Bleach wiki]
[Ichimaru Gin page]
Aizen slashes him vertically across the chest. The Hōgyoku disintegrates in Gin's hand and reassembles itself in the cross-like structure at the center of Aizen's chest. Gin reaches for it but Aizen grabs him by the wrist and rips off his right arm and impales Gin through the chest with his blade. Aizen then states that fear is necessary for evolution, the fear that one could be annihilated at any moment. He then thanks Gin for his efforts as he now has risen to an existence that surpasses both Shinigami and Hollow. Aizen throws Gin into a nearby building. Rangiku arrives unharmed and screams his name, she holds him in her arms and cries as Gin dies he affirms to himself that he failed as in the end he couldn't get back what was taken from her and that he is glad he said he was sorry.
[Matsumoto Rangiku page]
Rangiku awakens feeling out of breath and immediately identifies that Gin used the Hakufuku Kidō spell to knock her out. Rangiku arrives to seen Gin's fallen body and screams out his name. She holds him in her arms; as she realizes he is dead, she cries. Aizen closes in on them as Rangiku grieves for Gin, but Aizen's attention is drawn away from them as Ichigo arrives with his unconscious father to confront him.
