I want to use this quirk in a fic, but I dont have a plot for it.

Izuku Midoriya

Quirk: Aura Manipulation-

He can manipulate the emotional auras that surround himself and others. He can also produce a small healing or damage aura that extends 5 feet around himself.

Drawbacks: The more he uses it the more emotionally unstable he becomes. Useing it also saps his energy causing him to be come tired.

Overuse: Overuse can lead to a full emotional breakdown or him slipping into a state of kalopsia, depending on if positive or negative emotions were manipulated more over the other. Overuse can also lead to nose bleeds, headaches and unconsciousness.

I also want to pair this quirk with a minor mutation. Izuku would have a minor mutation of an angel, si he would have small white wings on his back and a halo, but he wouldn't be able to fly because of the size of his wings.
