Yeah, but he's also a veteran officer and one of the old man's favorites. He doesn't stress about anything less than the really important things.

I will also note that during the Ryoka invasion, Kyoraku was the only Captain who actually successfully stopped his target. And the only reason it took him longer than a minute or so was because he was trying for a peaceful solution.

Plus, you know, he has excellent fashion sense. How could I possibly not find him my favorite captain?

(Personal hope? Kyoraku beats the hell out of Bach at some point.

"Hey there. My name is Kyoraku Shunsui, pleased to meet you. Normally, I'd offer you a drink, try to resolve this reasonably. Unfortunately, you killed the closest thing I have to a father. So... Bankai."

I am aware that it will probably just end up being Ichigo responsible for the end fight with Bach, but a man can dream.)
