Looking forward to next week, or rather, this thursday, if we get info on the Gotei 13, which they hinted at in this little reveal.

So I guess Kirge was part of the Stern Ritter, but being the Hunting Corps captain is a special duty? Makes sense, Kirge was very powerful, stronger than some of the Stern Ritter shown.
