(A young boy named Kenji Lee has saved both Izuku and Shoto from the Sludge villain as Katsuki tries to blow it away. In the end of the fight, everyone was cheering Bakugo while Izuku and Shoto are scolded for "being reckless". When his parents Patrick and Rebecca found out about it, they started neglecting Kenji and favoring his brother Lewis Lee. His uncle Minato found out about the negligence and exposed it.)

Judge: I have decided. Minato Lee will have the custody of Kenji Lee. As for Patrick, Rebecca and Lewis, you'll be receiving a restriction order. You must not approach Kenji ever again. If you do, you're going to spend a serious period in jail.

(Patrick was enraged by Minato having the custody of his son while Lewis simply didn't care about it as he already knew it would happen.)

(At Minato's house, Kenji and his uncle go to the basement, where Minato presses a button which opens a secret door leading them to a secret room.)

Minato: I heard that your former friends decided to be friends with that bastard Lewis instead. But it doesn't mean you can't be a hero.

Kenji: (confused) What do you mean, uncle Minato?

(Then Minato opens the vault which reveals two transformation devices.)

Minato: I used these when I had your age. They gave me the power to protect the people, the innocent, the powerless, those who can't protect themselves.

Kenji: I see...

Minato: From now on, you'll be using them.

Kenji: Thanks, uncle Minato. You're the only family I ever had.

(Then they have a hug.)

(Some hours later at Union City, Kenji is seen on the top of a building as he uses his Dino Minder.)

Kenji: Bakuryu Change!

(Then Kenji becomes Abarekiller.)

Abarekiller: Excellent Excitement! AbareKiller!

(Then he sees fifteen thugs running around.)

Abarekiller: It's Show Time!
