Intro
That day, Iori was being beaten as usual. His father's fists and shouts rained down mercilessly on his thin frame. He caught a glimpse of Hinata, whom he was shielding behind his back, crying and begging him to stop. Iori didn't have the strength left to comfort him.
@Father: You little... piece of...!!!
The fist thrown with those words connected squarely with Iori's cheek.
Guh...!
As Iori collapsed with a thud, the father lost interest in him and turned his fist toward Hinata, who had been hiding behind him.
...!
WHACK!!
Waaaaaaah!!
Iori shielded him at the last second. The blow shouldn't have hit. Even so, Hinata wailed at the top of his lungs.
