Arrival in Karakura Town

Prelude
As Aizen arrives at the Dangai Precipice World world with Gin, he remarks on how nostalgic it is, and asks Gin if he feels the same. He suddenly notices the Kōtotsu, which rapidly approaches them from behind. Gin recommends that they move on, reminding him that an entity like the Kōtotsu dwells in the realm of reason, not in the realm of Reiatsu, and is thus not something that should be messed with using Reiatsu. Despite Gin's warning, Aizen allows it to collide with him, causing it to explode on impact. Aizen asks Gin what he was afraid of, remarking that reason only exists for those that cannot live without it. As the two reach the Dangai's exit, Aizen declares that they would go on to the edge of reason. Arriving at the Soul Society, Aizen sees that they are not in Karakura Town, and remarks that they were off by a little. Gin tells him not to blame him, explaining that Aizen had caused the axis to slip by destroying the Kōtotsu. Aizen admits that this is true, and apologizes for his actions, before inviting Gin to walk the rest of the way.
