"Over here" Kat shouted as she dashed forward into the fray. It was actually a little fast for Kamiko to understand, but when the other demon eventually turned around she'd be able to tell what Kat meant very quickly.
Kat decided very quickly the brute force approach was necessary. As she swiped her fans through the horde, she found them underwhelming. She had no skill, no technique, no understanding in the slightest about what she actually needed to do with them, just using overwhelming power.
The first batch of rats she hit were all with the flat of the fan, crushing their bodies against the heavy weight of them, but ultimately, doing more to disperse the horde then to deal any lasting damage against it. Kat, without thinking dismissed her fans and they faded away, and Kat spread her fingers wide and further sped up the energy around her body.
