At this moment, above Karakura Town.
Kurosaki Isshin was still fighting like a madman against the Arrancar maintaining the appearance of a black-haired delinquent teenager.
What Kurosaki Isshin did not know was that the Arrancar, whom he saw as the enemy who had stolen his wife... was merely an illusion created by Kyōka Suigetsu.
