She's good at this; Beyond can give her credit for that. He can tell he's hopelessly outmatched, the same way he was with Shiro - the only difference is that Johanna's combat abilities aren't supernatural, just finely honed.

No. Not the only difference. Shiro knew him, knew his secrets, inner thoughts he shared with her that she then turned against him. This fight with Johanna, it's not personal, not in the same way. She's reacting. Beyond recognizes this because it's how he too operates. It's an effective strategy for the short run, but for a long-term approach, it's not sustainable.

He's always been shortsighted, never able to envision a future past his immediate goals. Maybe that's why he's not able to fend off Johanna's next attacks - because he's simply reacting. He's knocked backwards, dizzy, and hits the ground hard, gasping for air.
