Background

Su Youzi is a transmigrant who finds herself in an eroge world and gains access to the Operator Cultivation system, through which she can draw and cultivate Operators. Her earliest draws include Unohana Chiyo and the seven-star Soga Toyura. 6

Twelve years before the main story, Su Youzi protected Soga Toyura from a Calamity Beast and fell into the Abyss, becoming an Abyssal Anomaly. Toyura used Mental Manipulation in an attempt to bring her back. To conceal Youzi's fall, the twins exchanged identities; Youzi cut her long hair, and her childhood was reshaped around the resulting secret. 233

For years, she was publicly regarded as a failed Telekinetic Ability User. Unable to advance and dismissed by the Soga clan as a disgrace, she was excluded from clan banquets and forced to live in the shadow of Toyura's reputation. 59 Her power is eventually identified as the era's sole Rule-based Ability, placing her at the center of attention from groups including the Eye of Insight and Manifest Manufacturing. 116

Appearance

Su Youzi is a short-haired, crimson-eyed girl whose appearance was changed after the Soga family concealed her anomalous past. She is frequently associated with a distinctive citrus-like fragrance. 2 14 233

• Short black hair, cut above her shoulders. 2
• Crimson eyes characteristic of the Soga bloodline. 30
• Often wears practical, youthful clothing such as a dark brown hoodie and hot pants. 2
• Previously had long hair before the identity switch with Soga Toyura. 233
• Her scent is repeatedly described as fresh and citrus-like. 14 338

Personality

Su Youzi is attentive and protective toward people she considers hers. She comforts injured Operators, protects Sakai Miho over her research value, heals Zero despite not understanding the Black Gear, and refuses to abandon allies in crisis. 109 115 128

She is also playful, provocative, and highly aware of her ability to influence others. She teases rivals and allies alike, uses affection and gifts to strengthen bonds, and can turn an interrogation or confrontation into a situation she controls. 80 346 471 Her charm becomes increasingly pervasive as Reverse Logic Hand develops into an aura that subtly twists people and circumstances around her. 488 723

Despite being repeatedly told that she is destined to rule or ascend a throne, Su Youzi rejects passive obedience to fate. She wants to experience the world on her own terms and repeatedly chooses to confront predetermined outcomes rather than accept them. 185 678
