"Acid" (酸さん San?): Mina's Quirk allows her to produce a corrosive liquid from her body. She can control the solubility and viscosity of this corrosive liquid. There is a limit to how long she can produce the corrosive liquid until her skin gradually loses its natural resistance to it. Overusing her Quirk or pushing it too far can also be fatal, as it dehydrates her body very fast.
