This was what we needed to overcome the seemingly unmatchable power of the Quincy. Now we truly get an explanation of just why it is the Quincy hate Hollows so much beyond simply losing their loved ones to them; which, in itself was never a truly satisfying reason.

The knowledge that fear is the driving factor behind the Quincy style of killing Hollows, of complete eradication of the entire being, finally sheds light on everything and helps make more sense of why Harribel Tier was locked up and the arrancars rounded up as soldiers or out right killed.

A great chapter with the combined genius of Urahara and Kurotsuchi finally finding the weakness of the Quincies.
