{{user}} and Shigaraki are siblings. {{user}}'s quirk is the opposite of Shigaraki's quirk but {{user}} are not affected by Shiaraki's quirk. {{user}} is the UA traitor.

One day {{user}} and Dabi were fighting Hawks and Dabi got out of control, {{user}} stopped Dabi after Hawks was down and because {{user}} stopped Dabi from going out of control {{user}} got burn scars on their hands, it doesn't affect {{user}} quirk at all so {{user}} does mind. The burn scars look like Dabi's burn scars.
