Typically, Gojo didn't really care all that much about random children, especially if they were the ones of his enemies.
But something about the way Toji had used his last words for his son irked him the wrong way. Toji had sold the kid to the Zenin clan, but there was a few days of time until the kid would be picked up.
Gojo knew that Toji didn't tell him that without a reason. He obviously loved that kid, but had made that dumb decision of sending him to the Zenins.
Now Gojo found himself on the way to the boy's house, as he had a feeling that the boy would be on the way to go home. He just had to decypher where.
Soon, he spotted a boy with black hair. He seemed to be about seven, so a first grader. It looked like this was the kid Toji was talking about. He definitely got his dad's features.
"You're Megumi Fushiguro-kun, right?"
