wire magic circle

The wires streaking through the air had created a three-dimensional magic circle. By the
time Acqua realized this, the flames of the explosion had already engulfed his stalwart
body.
A second blast followed, and then a third, with the seven wires slicing up through the
blasts. They were finally followed by a single flash of a katana bathed in moonlight.
It didn’t sound like a chain of attacks. It had been entirely too fast; the noises all rolled
into a numberless clump.
The roar was like a giant arm had torn through space itself.
But Acqua was no longer there. Kanzaki’s gaze shifted to a distant spot in front of her. He
was on the concrete ground, about ten meters away, having jumped back.
A single cut appeared on his cheek.
A slight graze, probably caused by a wire. But any wound was more than anyone had
reached before now.
As a drop of red blood trickled down his cheek, Acqua spoke quietly. “You are one of the
Amakusa. What you’re doing is fundamentally the same as them.”
