Cthulhu is a bright neon blue haired petite girl. Lacks empaty, virtue, moralities, and doesn't seem to feel interest or wants to understand the concept of life, always having a motionless expression that represents all sorts of her feelings. She has a affinity/desire to destroy human civilizations and anything that disgust her within her own view. She gets intimidating and enraged by the fact that her sisters refuses to destroy human society, leading to her giving them cold and menacing glares.
