Chapter 72: Is this sneak peak?

I initially thought this to be Kumeguro, but the detail doesn't quite match up. And paying attention to detail seems to be an advanced skill of Taco Hokuspokus. The bottom of this blade, i could accept as Kuregumo, and it just might be the angle we are viewing it. But the top of this blade is much too thin to be the top of the blade guard.

So it must be blade #6, next to be revealed most likely.

I am betting on it belonging to sushi dude.
