The Kaminari Twins

Prologe

Denki and Arashi, two inseparable twins until Arashi was taken away in an accident.
Denki and Arashi were playing at a park by themselves, and a man with no face, just smoke appeared and a boy, with badly dyed blue hair and a face covered in grey hands came out and almost grabbed Denki, but Arashi pushed him out of the way, he was a very protective older sibling.
"Don't forget me, Otōto." He'd said before he was dragged away.
"NII-SAN!"
Denki and Arashi always has been close, they even got lockets that had photos of each other in them, Arashi had been wearing his that day.
They were beautiful half watches that showed the time on one side and a photo on the other.

Denki refused to wear his own jacket, he wore the giant oversized hoodie that his brother had bought for himself years in the future, but the way it fit them then, it was a dress on the two of them.
It was a beautiful black leather jacket that had purple fur on the top, it was warm and Denki never took it off.

He trained his quirk hard and well. He refused to stop training until his hands would start bleeding from exposure to the electricity.
He got into UA, and was happy. But he refused to stay happy until he and his brother were together once again.
When he got there, he went up to the principle during an open house and asked if he could wear his jacket instead of the blazer.
Nezu agreed and allowed him to wear the jacket.
"I promise you, Nii-San, I'll become a hero and save you.
