Black Star/Tsubaki vs Zoro (Pre Time Skip)

No prep
To the death or knockout
No BFR
Fight takes place outside the vatican

Black Star is pretty damn fast. But I'm not sure he's fast enough.

He can rival him in pain resistence. Black Star's effing crazy.

Black Star is really fast for a Soul Eater character, but overall SE characters tend to be slower than OP ones. And power wise, I'd pretty sure Zoro has a significant edge.

I'd say Zoro wins this one.
