Vol 1 Skill 12 (Prediction accurate within 1mm)

Ikki swung downward with a flash, and in that moment, the space Ikki sheared through shined bright. Kirihara's body was visible in the middle of that light, and he fell on his back onto the ground already unconscious, turning up the whites of his eyes, spouting foam from his mouth, but… without injury. He had been cut so shallowly he wasn't even bleeding from the skin on the tip of his nose.

Ikki understood that Kirihara was giving up, and had no intention of killing Kirihara from the beginning. And yet―

The predicted distance was off by a millimeter, huh.

―yet even though he hadn't intended to wound, the sword edge did slightly touch skin. It was only because the power of Kirihara's arrows made reading the distance difficult.

My training's still lacking, I guess? There's still a long way to go.

And seeing that the Hunter was defeated by the sword-wielding beast before him―

"Shizuya Kirihara can no longer fight! The winner, Ikki Kurogane!"

―the referee announced Ikki's first victory.
