Kyrie widened his eyes, feeling the blade hitting his back. The fire hide did a good job at stopping part of its striking power, not a single slash done on it, he could feel. While the hide took no damage, the same couldn't be said about his back.
The cloth absorbed some damage, but it was not enough to stop the full momentum and edge of the blade from connecting. In other words, the hide was intact, but Kyrie's back didn't boast of the same resistance as the hide.
A cut was made on his back, the edge bypassing the fur and hitting on flesh by sheer momentum and impact, Kyrie widened his eyes in surprise, an event most unexpected happening right before his eyes.
Kyrie did not turn his back to attack Takemikazuchi, instead, he left the fire spring up automatically, connecting to his blade and jumping like a spear. The samurai warrior widened his eyes.
