On Sōkyoku Hill, having been attacked by 7th Division Captain Sajin Komamura's Shikai, Tenken, 5th Division Captain Sousuke Aizen casually holds back Komamura's Zanpakutō with his left hand and notes that it has been a long time since he saw Komamura's face before inquiring what brought about the change. Angered by Aizen grinning at him like this, Komamura declares that he will pay for betraying and deceiving them alongside 9th Division Captain Kaname Tōsen, who stands beside Aizen.
