His foot hit the pavement and he just kept going forward, taking another step with his right leg and bringing the tip of the sword to about a foot away from himself. His right hand wasn't idle though, and even as he moved forward, keeping pace with the backward skid he'd pushed Vos into, he brought the bat forward, swinging it hard toward the hand that held the sword pointed at himself. If it were a fully human hand being hit, the bones would be all but ground to powder by the successive shocks of the strike followed by the reflection of the force a moment later, and even for Vos' hardened bones it would likely mean a great many fractures and splinters that would leave the hand almost useless.
The bat would strike at the same moment the sword was leveled at his face, and this meant that his enemy would be forced to choose. Harm the armored biker at the cost of his dexterity or abandon the (unbeknownst to Sev) acid jet attack and retreat to attack another way.
