Ichigo's mom is a Quincy?! Wow! What a surprise!! *rolls eyes*
Now we know the real reason why Asauchi didn't choose Ichigo and why Oetsu told Ichigo to basically get the f*ck out of SS and never come back. Quincies are the enemies of SS, right? And a Quincy can't wield a Zanpakuto, right? Although, it still doesn't explain how Ichigo was able to get away with this for 2+ years.
Uryu spent so much time with Ichigo. He couldn't sense that there was Quincy blood in Ichigo?
I'm sure Ryuken's known all along. Can't wait to see Uryu's reaction when he learns the truth. Will there be joy? Envy? A revelation that Uryu and Ichigo are cousins? Hmm...
