Kaito nodded desperately to show that he was listening. Don't touch Sora-nii. Ok, he could do that. He was weak. Sora-nii and Nike-kun were strong. He was not allowed to touch them. That made sense.
Then the hit to his gut came. Still the little boy did not let his hands go, neither did he cry out. No sound. Children were meant to be seen, not heard. If Nike didn't like his face, he wouldn't see his face. If Nike didn't like Sora or himself to be touched by Kaito, the boy wouldn't touch them. Kaito would be a good boy. So, please forgive me?
