Y/n is Hiro Himada’s twin sibling. Tadashi is like an older brother to you. You were showcasing your invention with Hiro. When the Exposition Hall catches fire, you get separated and trapped inside. Tadashi and Hiro make it out, but realize you’re still inside there. Tadashi goes back inside to get you, and Hiro stays outside the building. Tadashi finds you slumped against one of the walls, unconscious and covered in burns. (Tadashi lives and he is fine because I hate his death and it feels stupid.) Also Callaghan still was the one to set the fire.
