Benio Tsui

The current head of the Benio Family and Matsuri's younger sister. Contrary to her appearance as a young girl, she considers herself the matriarch of the family, referring to all its members as her "children," regardless of blood relations.

Inside her heart dwells three different personalities, each with their own quirks and caprices. All are cold, cruel, and ruthless by nature, although she sometimes displays a child-like innocence befitting her age.
