Gloria

Cinders' older step sister. She is stubborn, and desperately tries to imitate and please Carmosa to the extent of losing herself in the process. 

She has a tense relationship with Sophia due to the latter's apathy, sharp tongue, and general attitude, but in her own way is as much a slave to Carmosa's will and temper as her sister and Cinders, despite being the favoured daughter. She is more reasonable and fair than her mother if given a chance to show her true colors though. 

As with Sophia, whether or not she can be befriended, and/or reconciled with her sister depends on the player's actions.
