Arrival in Karakura Town

Prelude
In the fake Karakura Town, when Ichigo turns to look at Aizen's fight against his father, Urahara, and Yoruichi. Gin appears behind Ichigo and remarks that Ichigo should not turn away when he's standing right next to him. He goes on to tell Ichigo that he is no longer a warrior, Shinigami, Hollow or even a human anymore. He asks Ichigo if he thinks that he can beat Aizen when his father, Urahara and Yoruichi cannot. Seeing how weak Ichigo's resolve is, he again offers to allow Ichigo to run, saying that he has lost interest in him and that Aizen will be disappointed to see him as he is. Gin finishes by saying that Ichigo 'knows' about Aizen's power. He then tells him that is all the warning he is going to give Ichigo and that he is not going to run, he will finish him off. As Gin draws his Zanpakutō, he is stopped by Aizen. Ichigo sees that Aizen has completely defeated his opponents, all three of them lying on the ground. Aizen then asks what Gin was going to do to Ichigo, he simply replies that he was testing Ichigo's strength. Aizen instructs Gin to open a Senkaimon so that they can attack the real Karakura Town in Soul Society, remarking that there is no need to destroy the Tenkai Kecchu since it will be more convenient to create the Ōken in Soul Society if they are attacking the Royal Palace. Ichigo tells him to wait, but falls silent as Aizen's body begins to shed his sleek new form as his "incubation" is complete. Gin remarks that his incubation period has ended and Aizen agrees, finding that it fortuitous that the Chrysalis period has ended as he will be able to watch the demise of Soul Society with his own eyes. Gin opens the Senkaimon and before leaving, Aizen tells Ichigo that he will leave him in the fake Karakura Town and come back for him after everything else is done. Aizen then enters the Senkaimon with Gin. .

As they travel through the Dangai Precipice World, Gin comments on the nostalgic feel of the place. Aizen agrees before they are confronted with the. Gin urges Aizen to get going but Aizen holds his ground, prompting Gin to comment that as the Kōtotsu is a being of reason and not Reiatsu, as such, nothing can be done to it with Reiatsu. However, Aizen continues to hold his ground and then destroys the Kōtotsu as it gets close. Aizen then asks Gin what he is afraid of, saying that reason is for those who cannot live without clinging to it. Aizen then invites Gin to come with him to reason's horizon. Once they arrive in Soul Society, Aizen notes that they are some distance away from where Karakura Town is. Gin asks Aizen not to make it sound as if it was his fault, blaming it squarely on Aizen's destroying the Kōtotsu. Aizen concedes that, that might be the case and apologies before inviting Gin to walk the rest of the way.
