“Try saying that again, dammit!!” Kamijou yelled from his bottom of his gut and aimed for the area between Hamazura’s chin and lower lip with his forehead. With a sound like a flower pot that had been dropped from somewhere high up, Hamazura’s neck bent backwards.
Kamijou then slammed his clenched fist into the top of Hamazura’s nose. Hamazura’s body arced backwards and fell to the ground. “Agaaaaahhh!!”
Hamazura rolled on the ground holding his nose and Kamijou tried to kick him. But the damage he had taken must have affected him more than he had thought, because his footing faltered.
“Shit...You have a sloppy way of fighting.” Hamazura had managed to stand back up.
