Rewind

Rewind is a quirk used by Eri

Description
Eri's quirk allows her to rewind a persons body back to a previous state, as seen when she was able to reverse the fusion of Overhaul and Chronostasis. She is even shown to be able to revert people back to a state before they even existed, as seen when she accidentally did this to her father. Currently the full effects and restrictions of her quirk are unknown.

One of the effects of her quirk can apparently be put into a bullet and used to attack a persons quirk and prevent the activation of that quirk, though it is unclear whether that it is the true effect of the bullet or the perceived effect
