Union's Executioner And Busters' Saving Mission

U.A Academy was a school for people with quirks so they can become a hero, until someone brought the school which allows people also with Sacred Gears and Semblances or Ninja Skills and changed the name Into Union Academy.

But no one seems to realise that Union Academy was very corrupted, which some of the students came for fame or money and sometimes they don't care about civilians...... But that's not the point of the story.

this is about a boy who lost everything 5 years ago and Union Academy wasn't there to save which he blames them, then the boy was able to find items that gives him power and starts using them to try and destroy union academy and kill any criminals.

While there's a man who was reincarnated by a god who requested him to save the universe he'll be reincarnate in and stops the threat.

Then the boy met a group which that man is in along the way who's also fighting against Union Academy, but he doesn't trust them and prefers to go alone.

but a few people from that group tells the boy that if he keeps up with the killing his guilt will follow him, will the boy trust what they say and join them?...... or will he kill them as well and get his revenge.

P.s, I asked someone to use their OC and their name is @DemonicDeku
