Well Shunsui is having some fun here, but he should not have a problem with this guy, in fact he should make short work of him, he is the captain commander for goodness sakes.
I liked his little banter with Nanao, though why did they have to shadow her out in one panel, and another panel in the same page we see her, like it is suppose to be a big reveal. If she wasn't wearing her glasses that is a different story.
Well unlike the Vizzards, Shunsui has no choice but to reveal how to beat him, because it is not a game until the rules are agreed to.
