Personality
Aya is an extremely sadistic and cruel individual, taking pleasure in causing death of innocent only for her self-sastifaction, particularly on a massive scale. She also of little importance to the people close to her when she tried to kill her own daughter who spent decades trying to figure out a way to release her from the prison of the Monster District. The best demonstration was when she simply crossed Natsuki's body with a demonic blade using her own daughter as a decoy, Yuuma, and laughed sophisticatedly when she saw her daughter die as something more than simple breathing. Aya also likes to make people suffer before killing them, through the majority of psychological torture through the feelings of the people, which is why she does not kill her enemies outright. A remarkable fact is that she has mentally tortured every person to fight against her.

She is a selfish person and has a dry sense of humor, and is always calm, cold and insensitive to any kind of thing. She is rarely caught by surprise and hardly changes the facial expression to despair, fear, anger, greed or other sentiment. Aya is very insensitive and not care about anyone but herself and also nothing but her powers, being able to commit atrocities and horrible things just to get the full power. Aya's personality is the complete opposite of her daughter hearted, gentle and peaceful light of Yuuma, who despite being the biological daughter of her, she did not showed the same evil like her mother.

She refers to her daughter as a doll and disposable product as all mankind. She is usually able to react to any situation evenly and only loses her temper even when her full power is not enough against an enemy.
