He had failed to get up off his back even after falling a floor and the wanted criminal was leaning down on him. The helmeted man held something in his hands. It was the bicycle handle used for the fore grip of the smashed crossbow.

Since it had broken, the edge of the metal pipe was quite sharp.

Still in the mounted position, he aimed for the visor of Hamazura’s defenseless face.

“Ogwah!?”

If his opponent would not stop resisting, he would keep swinging down that sharp pipe until the boy stopped moving.

“Bghah!! Gh, ewhah!?”

He had not given up yet.
