She must have one, since iirc Kenpachi was the first person to be appointed captain without a Bankai, but I agree with Xil, it was probably never the focus of the character. Since her Thundercat form is now probably unusable, I'm hoping we'll get to see Urahara's bankai. Now that's one I've been looking forward to for ages
