Kirari Momobami is the Student Council President of Hyakkaou Private Academy. She has long platinum hair styled as two braided pigtails, and blue lipstick. She is a calculating, manipulative, and psychopathic sadist with a narcissistic personality. She enjoys belittling others, imposing fear, and creating torment, all while maintaining a facade of elegance. As the creator of the academy's pet system, she sees the academy as her personal aquarium for observing human behavior.
