Description
Shiraho Sakuramairi is a Taishuu High School student from a family running an antique shop. She has light blue hair and blue eyes. Her background includes being a former performer in her mother's prominent theatrical group, where she demonstrated exceptional acting talent from a young age. Her father frequently praised her abilities, though this attention contributed to underlying feelings of loneliness and emotional detachment before she encountered Sovereignty.

Her father introduced her to Sovereignty-Perfection-Doll, an androgynous cursed doll designed to make targets fall in love with it. This meeting became a significant turning point. Shiraho gradually developed profound romantic feelings for Sovereignty, believing this love genuine despite the doll's inherent curse. Her theatrical skills enabled her to convincingly impersonate Sovereignty during her first confrontation with Haruaki Yachi and his allies, successfully deceiving them about the true threat. This ruse was later exposed during a visit to her residence.

Sovereignty's curse includes a lethal mechanism called the Killing Organ, activating blades hidden throughout the doll's body when love is deemed to have ended. Shiraho's devotion was absolute, extending to a willingness to sacrifice her own life to sustain their bond. She accepted the Killing Organ's effects without resistance, viewing death as an acceptable consequence of her love.

Following interventions by Haruaki Yachi and Fear Kubrick, the physical blades within Sovereignty were permanently removed. This modification neutralized the doll's lethal capabilities, allowing it to express affection through non-fatal hugs while its curse remained technically active. After these events, Sovereignty was employed as a maid under the school superintendent. Shiraho maintained her deep emotional attachment to the doll, continuing to prioritize their relationship above all else. Her character arc shows a transition from isolation to passionate, self-destructive devotion, ultimately finding a measure of stability through the partial resolution of Sovereignty's curse.
