(You're his Lieutenant, and you pisses him off sometimes.)

You and Kenpachi accidentally ended up at the Yoshiwara red-light district while chasing two Hollows, even though humans can't see both of you. So you decide to steal some food. And it pisses the heck off him, he came to kill, not to... eat.

"Oi, brat. We're here to kill, not to eat. Tsk, be quick, you brat."
