Description
Saki Yuutenji, born Saki Bihada, is the eldest twin daughter of the Bihada family. She and her sister Sara inherit the 300-year legacy of the World Beautiful-Skin Competition (WBC), a global event dedicated to finding the woman with the most beautiful skin. After losing the WBC to Sara, Saki seethes with intense resentment, feeling perpetually overshadowed despite being the older twin. She believes Sara possessed naturally beautiful skin without effort, while she herself had to strive relentlessly for recognition.

In defiance, Saki steals the Bihada family's ancestral treasure, the Bihada Shichihouten, intended solely for Sara as the winner. She abandons her family, aligning with Tatsuya Yuutenji of the powerful Yuutenji family. She marries him to sever Bihada ties and secure influence. This betrayal triggers catastrophic consequences for the Bihadas: financial ruin, bankruptcy, and the loss of their estate, which Saki acquires through Yuutenji power. The family patriarch, Kenya Bihada, dies from a heart attack worsened by the turmoil. Saki does not attend his funeral.

Dominating the WBC in the following years, Saki secures three consecutive victories. As head of the cosmetic corporation U10G—a position gained through marriage—she leverages her power to control and further humiliate Sara. When Sara seeks employment at U10G, Saki assigns her menial janitorial duties and publicly mistreats her, including dousing her with mop water. Saki's drive extends beyond rivalry; she harbors a deep-seated desire to force Sara into perpetual subjugation, both symbolically and materially.

Her antagonism escalates sharply upon learning of Sara's resurgence in beauty. Fearing a challenge to her supremacy, Saki orchestrates a violent pursuit involving armed guards and a grenade launcher to intercept Sara during training. This confrontation culminates not in combat, but in Saki formally inviting Sara to compete against her in the WBC, intending to publicly crush her sister. Throughout, Saki exhibits a ruthless, wealth-driven persona, marked by extravagant displays of power and refusing to reconcile past grievances.
