Reincarnated As The Villain's Younger Brother [On Hold]

~~~~~~~~~~~~~~~~~~~~~~~
This is kind of my first time writing something like this but I'll try my best to make this entertaining.
~~~~~~~~~~~~~~~~~~~~~~~

A boy named, "Akito" along with his classmates were stuck in their school as it bursted into flames. He stays back to help the remaining people get out.

By doing this the exits get sealed from almost every turn except the roof top. As he has a accident on his way out and reaches the rooftop with a limped leg. He is faced with a problem.

He would have to go down by jumping or down rigidy stairs. Akito chose to go down the stairs but ends up falling to his death.

His sacrifice wasn't in vain because those he saved went on to thank him.

As he opens his eyes he meets a celestial being that told him that he would be talking his favorite characters place.

Will he be able to change this characters life?
