Rukia was at one point 3-0. That is a pretty good feat when you’re in the same series as Ichigo, Zaraki, Byakuya, Grimmjow, and other heavy hitters. Of course Bly is a lot stronger than her previous opponents. Bly wins.

Update 8 7 2020 Rukia is a little too fast so Bly would have a hard time keeping up with her. Rukia wins.
