She is the class president of the most advanced class, Diamond Class.
Although she comes from a family with a long history and is a lady in her own right, her language is so foul that it is hard to believe that she is a lady.
As a daughter of the same family, she sees Arianna as a strong rival, and she pokes fun at her at every opportunity.
However, she usually spins out of control and destroys herself.
