The moment Hitori saw Kamiya in the nerd who was getting beaten by the bully, he heard Kamiya's voice.
'What are you going to do? Watch? Or stop someone from suffering from the same fate? That fucking bully might not be as powerful as Onogi, but believe me, every bully is powerful for someone powerless.'
Hitori stood staring at the nerd, blood flowing from his nose, and he was trying to stop the bully. But the bully was too powerful for the nerd, he punched the nerd once again.
If he had closed his eyes, he was sure he would have seen Kamiya with that sympathetic frown on his face.
'Well, what are you waiting for? What are you going to do? Watch till the show is over?'
Why do they appear? he wondered, just to prompt me to do things.
Hitori clenched his fist and tried to control himself. I think I should, he thought.
Then he heard Kamiya once again while he saw the bully shouting at the nerd.
