Speed of Sound Slice

Kanzaki’s around two-meter-long Japanese sword sliced through the air. Her Nanasen
attack using seven wires flew towards Index at a speed that seemed to slice through
sound itself.
But she was not aiming for Index.
The wires tore through the fragile tatami mat at Index’s feet. Having lost her footing,
Index fell backwards. The magic circles linked to her eyes moved and the pillar of light
that was supposed to be aiming for Kamijou missed its target by quite a bit.
