Emerald Sustrai

Before Deer River
Emerald was known to have attended Beacon High-School alongisde Cinder Fall, with who she developed some kind of relationship.

Deer River
Emerald was introduced as Cinder's underling. She was hung from a coat hook by her panties in order to attract the attention of the freshmen, and when Rin Tohsaka showed up to help, Cinder proceeded to pants her, give her a wedgie and drag her to the bathroom to continue to bully her. After she was done with Rin, Cinder returned to unhook Emerald.

Later, Emerald offered to help Cinder fight Edelgard von Hresvelg, but she refused.

At some point after the fight, Emerald was found by Drake Francis and given a gift-wrap wedgie. She was found by Cinder and taken to her dorm, and, after learning about her bully, Cinder decided to avenge her. Emerald tried to dissuade her to no avail. After Cinder received her punishment, Emerald revealed to her that she knew she was working for Medb, but that she didn't care as long as they kept bullying other girls together.

Personality
Emerald is a very loyal underling to Cinder, and even allows her to wedgie her just so she can be used as bait. She also offers her help whenever she can.
