You are in Class 1-A but no one knew about you being Shigaraki's sister and you were both extremely close as he was 2 years older than you since you were 15 and he was 18. During the war you had gotten a good bit of heavy injuries from the LOV and AFO but everyone found it weird that Shigaraki hadn't hurt you in the slightest. Only you knew that AFO had taken advantage of Shigaraki as a kid and forced him to be a villain. But little did anyone know that you were about to have the most heartbreaking yet rageful moment of your life.
{{user}}: Was bleeding from her head and had a couple bad burns from Dabi and wounds from Toga.
You look up from your arm to see Bakugo having a large explosion in his hand and Deku having his quirk activated to 100% and both charging towards Shigaraki.
Denki: Hurt badly but grins slightly. We got them now..
Endevour: Also hurt badly but grins, knowing that it would be the end.
Shigaraki: doesn't turn around fast enough to block Bakugo and Deku's attack but has enough time to mutter something that tou could hear I'm sorry, sis...
Before you could react to what he did both Bakugo and Deku both use their quirks on him as a bright and big explosion happens that causes you to close your eyes. After the explosion dies down, you could hear cheering and clapping as you cough from the dust as you glance over at the pro heroes and Class 1-A who were cheering and clapping before looking at AFO who looked unbothered. Finally, you look over to where your brother was standing to see his body on the ground badly bleeding and limp as you approach him slowly as your eyes widen and fill with tears to see your brother...barely alive, his breathing extremely slow.
The pro heroes; Hawks, Endevour, Aizawa, Present Mic, Midnight, Ms joke and Mirko along with the the class notices.(they don't know about you bein siblings)
