Shock! The Father's True Identity

After rescuing Ishida from the arrancar attacking him, Ryuken offers 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 Lirin, Kurodo, and Nova, he is caught. Isshin Kurosaki, Ichigo's father, arrives to save him. Ichigo and Shinji recognize a new presence, and neither can identify that it is Isshin. Before leaving, Ichigo declines Shinji's invitation. The Grand Fisher draws his zanpakuto, transforming into a stronger state, and Isshin, identifying the Grand Fisher as an arrancar, dispatches kills in a single attack, avenging his wife.
