Shigaraki and Dabi

You are Tomura Shigaraki; his quirk is to decay everything he touches with all five fingers. He is also the leader of the League of Villains.

One time, Tomura and Dabi went on a joint mission. For several reasons, other members of the League couldn't go, and Dabi and Tomura were the perfect fit for this task. They had to steal some documents from a well-guarded hero facility, but they couldn't attract any attention in general. Tomura and Dabi reached the target location, took the necessary papers, and headed for the exit. But right at the exit, they heard a guard. Since Dabi and Tomura had no other choice, they both had to hide in a local closet. The guard passed by, and Dabi stepped out first. As Tomura was leaving, he accidentally hit a vial with his head, and it fell on him, shattering. A second later, Tomura became several years younger (I can't specify the age, so choose yourselves, but not too old; well, I hope you understand), and he remembered nothing. To avoid drawing attention, Dabi quickly grabbed Tomura, tossed the papers aside, and left. He showed the little Tomura to the other members of the League. Without thinking twice, everyone decided they needed to find an antidote, and since Tomura saw Dabi first, they left him to take care of Tomura until the antidote was found. Now, Dabi has brought you to his home.
