Ye Shiyu

Biodata

Power Progression

Background / History

Ye Shiyu spent her early childhood in Tianjing, Dragon Nation, with both parents. She remembered a generally warm household, although arguments between her parents worried her. Wanting to make them proud and prevent them from worrying, she studied after lights-out, earned first place in every subject, and pursued activities including sewing, dance, martial arts, and athletics 618 631.

Her martial-arts training began after her father expressed concern about her health. Her coach praised both her talent and her unusual perseverance during painful flexibility exercises. Seeing her parents pleased encouraged her to work hard at whatever they mentioned 618 631.

After her parents’ relationship broke down, Ye Shiyu left with Ye Lan. Her father refused to let her take her favorite doll, arguing that it did not belong to her because her name was not on it. She later retained a strong concern with ownership, including possessions marked with her name 36 91.

Ye Lan and Yan Huan’s mother, Wang Yulu, had agreed to become godmothers to each other’s children. After moving to Linmen, Ye Shiyu met Yan Huan when Ye Lan welcomed him into their home and introduced him as her younger brother. They are neither biological siblings nor legally adoptive siblings; Ye Lan never completed adoption paperwork for him 4 13 410.

Appearance

• Hair: Waist-length, straight black hair, initially worn without accessories 4.
• Eyes: Deep black, slightly narrow and elongated beneath long lashes; her pupils turn violet during some supernatural activations 4 373.
• Build: Tall and well-proportioned, only a little shorter than the 184-centimeter Yan Huan, with visibly toned forearms 4.
• Complexion: Very fair skin that marks easily 4 27.
• Clothing: Frequently wears black and white. Her school uniform includes a white short-sleeved blouse, dark bow, black plaid skirt, black calf socks, and black leather shoes 358.
• Expression: Usually appears cold and doll-like. Changes in her eyes and mouth reveal emotions that Yan Huan gradually learns to recognize 484.
• Makeup: Initially wears none; later learns makeup techniques by secretly observing Bai Yi 4 674.

Personality

Ye Shiyu is quiet, socially withdrawn, and uncomfortable with unsolicited physical contact. She can go an entire school day without speaking to anyone, and other students describe her as difficult to approach. She finds dolls easier to deal with than people 17 36 399.

Her possessiveness grows from insecurity, territoriality, and fear of loss. Initially, she resents Yan Huan because she fears he will take Ye Lan’s affection away from her. After becoming attached to him, she struggles with the fact that he also cares about friends and other women. The author’s afterword explicitly identifies her lack of security and terror of losing others as central traits 13 72 665.

Her conscience remains active despite her repeated coercive behavior. Yan Huan’s kindness makes her feel ashamed of attempting to hypnotize him, and Ye Lan’s reprimands sometimes stop her from using newly acquired powers. Nevertheless, discomfort, jealousy, or the desire to possess something repeatedly drives her back to the Modifier 14 133 610.

Her emotional numbness worsens while she uses the Hypnosis App: for a time, only Ye Lan and Yan Huan reliably provoke an emotional response. After she stops using hypnosis following the Tokyo Tentacle Incident, her feelings become more visible. She begins trying to make friends and to understand Yan Huan’s experiences rather than merely secure his attention 220 410 513.

Abilities & Skills

Hypnosis App

Ye Shiyu’s principal supernatural ability imposes commands on targets through electronic screens 72.

• Screen-based activation: Her level-two upgrade lets her use nearby screens instead of displaying the app directly on her phone. She demonstrates this through a promotional television 72.
• Behavioral commands: Can compel a target to follow her, return to bed, or act as a distraction 72 84 162.
• Memory-related commands: Orders Yan Huan to sleep and forget a nighttime encounter 84.
• Independent bodily control: Can control someone’s body without controlling their mind, an ability she conceals when discussing powers with the other girls 280.
• Truth-seeking use: Uses hypnosis while questioning Zuo Jiangqin and assesses whether her statements are truthful 160.
• Electronic and internet reach: Later information identifies electronic devices and the internet as channels for her ability 616.
• Hardware dependence: A dead battery prevents an early activation. Destroying her phone can also interrupt her attempt to use it 14 318.

Index Finger’s Passive Defense

• Automatically bites through An Le’s restraining tentacles 220 274 373.
• Can be overwhelmed: An Le’s regenerating tentacles and Superconductor Mode progressively weaken Ye Shiyu’s resistance and slow the defensive response 373.
• Its influence can be temporarily nullified by the USB Drive’s shock wave 657.

Defeat CG

Ye Shiyu receives apparent future or failure-ending visions through her supernatural system 91 568.

• One ending depicts her abandoning hypnosis, becoming a loving older sister, and watching Yan Huan build a family with Hitomi Sakuramiya 91.
• Another depicts Yan Huan admitting that he deceived her and offering her only a secret relationship 568.
• These scenes are not established events. Yan Huan challenges their reliability, and later encounters diverge from the outcomes they predict 606 620.

Martial Arts and Athletics

Ye Shiyu trained for years and combines strong technique with quick reactions 108 226.

• Joint control: Immobilizes Spencer with a painful joint lock 108.

Equipment / Items

Relationships

• Yan Huan — Her godmother’s son and socially recognized younger brother, whom she pursues romantically. Their relationship includes repeated hypnosis, coercion, genuine affection, and attempts to distinguish love from possession. Yan Huan also identifies her as one of his most important family members 72 85 361 581.
• Ye Lan — Her mother and strongest source of discipline. Ye Lan condemns her treatment of Yan Huan, confiscates her phone, and promises to monitor her behavior, while supporting the possibility of a consensual relationship between them 85 162.
• Wang Yulu — Her godmother and Yan Huan’s mother. Wang Yulu’s affection for Ye Shiyu later alarms the other romantic rivals 13 675.
• Bai Yi — Rival, occasional ally, and reluctant confidante. Ye Shiyu eventually counts her as “half” a friend because she also wants Yan Huan; in an IF Route, she comforts Bai Yi and equips her for further travel 204 410 709 713.
• An Le — A rival whose conflict with Ye Shiyu escalates into supernatural attacks. Ye Shiyu later sincerely asks about Yan Huan’s childhood and says she no longer wants to keep fighting her 220 272 513.
• Hitomi Sakuramiya — An unstable ally and romantic competitor. Their alliance repeatedly breaks down, and Ye Shiyu rejects her proposal to share Yan Huan 204 312 525.
• Spencer — A rival she confronts verbally and physically. Their track contest becomes the means of completing a Modifier mission against Spencer 108 130.
• Mōri Hina — A younger student who helps with her brocade and becomes part of her effort to socialize normally. Hina later advises her on gaining recognition for her Student Council campaign 392 410 760.
