“I can see that..!” Yukimura was slowly being pushed to the defensive, being overwhelmed by the investigators strength. There was no beating her without using his kakuja, but that put Sasuke at risk- they didn’t have time to drag this out. It was likely Naotora alerted the CCG for backup, they’d have to finish the job quickly if they wanted to evade capture.
Yukimura released his kakuja, groaning in pain as his own Kagune started to dig into the flesh of his back, swatting Naotora hard to try and knock her back.
