There was not enough freedom or time for it to move out of the way by the time another attack came with another Tonfa.
Ash kept swinging the blunt part of the Tonfa toward the Spirit using the long end causing it to strike with a lot of force.
It followed up with yet another from the other Tonfa that she held in her other hand.
Each hit was followed up with another as she gave no room for any more openings to be exploited.
No matter how much the Spirit could struggle to free itself and try to fight back, the constant pressure it faced did not allow it to.
Each hit caused it pain and made it harder to follow up with what it wanted to do if given the opportunity.
Each moment that it was held back from being able to act, the closer it was to being fully subdued.
Ash was trying to wear it down to decrease its resistance and give it no opportunities to escape but she was creating enough time for the black bandage Evil Spirit to exploit.
