A new application of her semblance

Emerald was beyond bored working undercover at Beacon. Other than the occasional happening she had nothing to do but play the good student. This needed to change. The thief didn't want to cause any trouble for Cinder but she remembered something Cinder told her, that Emerald could further develop her semblance. Emerald decided to test it on Ruby since the innocence of the girl annoyed her.

Emerald had found Ruby in the locker room after she sparred with her team. Ruby had a surprisingly good body, with large breasts and a nice bouncy ass. Perfect for what Emerald had in mind. Hiding behind a wall while Ruby showered, Emerald focused on giving an illusion straight to Ruby's mind, basically rewriting what she thinks.
