Izuku Midoriya died.
He committed suicide.
In the battle between one's conviction and society's pressure, society won.
But Izuku's body didn't rot, instead it became the host to an wandering soul.
The soul belonged to an orphan. He was a victim of Eri's quirk.
But he didn't blame her.
Just before he died, he sensed the intent behind her action. It was his passive quirk that allowed him to do so.
She was ridden with so much guilt that he wouldn't have believed that she was just a little girl.
So much despair and helplessness.
He shuddered to think how much she had suffered.
In the last moment, he was overwhelmed by a simple desire.
The desire to save her from the abyss.
But it was too late.
After dying, instead of loosing his self and becoming one with the nature, he became a ghost.
Literally a translucent and floating ghost, invisible to the naked eye.
It was a morgue, where he first laid his eyes after becoming a ghost.
He was so confused. He tried talking to other people but nobody could hear him or see him.
Whenever he tried to touch someone, he just passed through them without any resistance.
People beimg murdered, childrens being kidnapped, hero dying at the hand of villains.
He could only helplessly watch.
He didn't know when his cursed existence would end.
He was floating aimlessly in the air when his sight came upon a small figure standing at the edge of the rooftop of a school building.
huh? Is he going to jump? he thought as he floated closer to the figure.
He had already seen countless people committing suicide.
After coming closer, he could see it was a boy with messy hair and round face. He was skinny. But it was the eyes that caught the ghost's attention.
Eyes full of despair and helplessness.
Eri. He remembered. He remembered the name of the girl by whose hand he died.
But he didn't blame her. He wanted to save her.
It was his last wish.
Not again!!! He glided in his full speed toward the boy who had already jumped.
He knew it was futile. He knew that he would just pass through anything he touched.
But still he tried and like every time the body just passed through his hands as he tried to catch the boy in midair.
But something was different this time. The moment the body touched the ground, the ghost felt a powerful suction force toward the ground, where the body fell.
What's happening? He panicked and tried to overcome the suction force.
It was of no use. All his resistances were futile.
Last thing he remembered before darkness overtook his eyes, was the lifeless body of the child with messy green hair.
AN: Don't complain about MC finding himself in the morgue. That's part of the mystery tag.
Eri's quirk leads to complete erasure of one's existence. Technically the victim is rewinded to nothingness.
