After rescuing his son from the arrancar attacking him, Ryuuken offers Uryuu the opportunity to restore his powers on the condition he never associates with Soul Reapers. Kon continues to flee from the Grand Fisher. Despite receiving help from Ririn, Kuroudo and Noba, he is still caught. Isshin Kurosaki, Ichigo's father, arrives to save him. Ichigo and Hirako recognize a new presence, and neither can identify that it is Isshin. Before leaving, Ichigo declines Hirako's invitation. The Grand Fisher draws his zanpakutou, transforming into a stronger state, and Isshin, identifying the Grand Fisher as an arrancar, kills him in a single attack, avenging his wife.
