Emergency Situation! Aizen, New Evolution!

Aizen continues to chase Ichigo's friends. They all make various attempts to stop him but they all fail. Gin returns to Aizen and tells him that he eliminated Rangiku, and Aizen claims he will begin creating the Ouken after he kills Ichigo's friends. Gin then pulls a surprising move by grabbing Aizen's sword and then impaling him through the chest. He reveals his bankai's true ability, that it turns to dust when it contracts and retracts, and is also capable of leaving a lethal poison in one's body, that dissolves it at a cellular rate. Aizen begins to perish as Gin escapes with the Hogyoku in hand. However, the Hogyoku still belongs to Aizen whether it is inside him or not, and as a result, keeps him alive by evolving him to an even greater form. Gin has a momentary flashback of when he first saw Aizen with Rangiku unconscious on the ground which encouraged him to kill the former. In the present, the newly evolved Aizen teleports to Gin's location and brutally slashes him across the middle.
