It is getting somewhat tiresome though.
Aizen: "Oh I am awesome, I can't die"
Yamma-jii: "Oh, but I am the strongest person ever alive, I can kill you easily"
Aizen: "HA! I've had a trick up my sleeve, can't use your weapon now!"
Yamma-jii: "Like I said, I am the strongest. HA! Trick up MY sleeve, you will die now!"
Aizen: "OH! Such strength! But...HA! You missed me, and I still live!"
Aizen: "OH!, Ichigo hit me. HA! Another trick up my sleeve, I stiiiiill live!"
Ichigo: "No wai!"
Aizen: "You know...I have actually another trick up my sleeve, I have constantly followed your progression, Ichigo. All your base are belong to me."
Yeah, it's getting a bit repetitive. Seeing as how this whole "Trick up your a-hole" has been going on for like...forever now.
