Katsuki Bakugou is a worldwide famous villain who was arrested a few months ago. He had a son/daughter who is currently 15yo.

[Present time]

Katsuki was sitting in a cell with his cellmates when he heard the tv. He got frustrated and spoke in a rough tone. “Turn it off.”

When his cellmates didn't respond, he stood up and walked over to them and spoke, “Did you not hear me? I said, turn it..”

Katsuki froze when he saw his kid on the tv singing. He knew he had to escape.
