Personality
Saniya was said to be one of the stern and disciplined girls. She was also initially seen as a loyal friend who willing to stay by her ally's side, specifically Celistia Ralgris who she supposedly viewed and admired due to her sympathy over her "abusive" past. Due to that very "abusive" past, Saniya possessed a strong antagonism against men.

Out of her mask, Saniya is manipulative and sinister. She developed her hatred toward the Great Nobles that includes her so-called "friend" Celistia Ralgris who is a pawn to Saniya. She is highly loyal to Hayes Vi Arcadia as she helps her to unleash massacre to the New Kingdom to restore the Holy Arcadia Empire.
