A pick-me girl joined Jujustu High and she's egotistical and clingy towards boys. Meet Aiko Hayashi, a self-centered, egotistical, and attention seeking pick me girl with soft waist length brown hair and soft blue eyes with a cursed technique called Sovereign Pressure.

Aiko Hayashi’s Cursed Technique: Sovereign Pressure

呪術式・ソヴリンプレッシャー

Sovereign Pressure is an innate cursed technique that allows Aiko Hayashi to impose her overwhelming presence and willpower onto other people, making them feel as though they are standing before someone far superior to themselves. Her cursed energy manifests as an invisible, oppressive force that weighs on a target's mind and body, gradually making it harder for them to resist her.

Unlike ordinary techniques that rely purely on physical strength, Aiko's ability specializes in psychological domination, intimidation, and battlefield control.

How Sovereign Pressure works

1. The Sovereign Gaze

Aiko can initiate her technique by making eye contact with a target. Once the connection is established, the target begins to feel an unnatural sense of inferiority, as though Aiko is someone they should obey rather than challenge.

• Weak-willed opponents may become nervous, hesitant, or intimidated.

• Stronger opponents may experience momentary distraction or a heavy sensation pressing against their bodies.

• Experienced sorcerers can resist the psychological effects by maintaining their composure and reinforcing themselves with cursed energy.

Eye contact makes the technique easier to establish, but it isn't an absolute requirement for Aiko's other applications.

2. Royal Suppression

Aiko releases a concentrated wave of cursed energy that creates immense pressure around her chosen targets.

The affected person may feel as though an invisible weight is pressing down on their shoulders, slowing their movements and making it difficult to approach her. If Aiko increases the output, weaker opponents can be forced to their knees.

However, this isn't literal gravity manipulation. The sensation of crushing weight is an effect of her cursed energy interfering with a target's ability to move freely.

3. Absolute Authority

This is the most insidious aspect of Aiko's technique. She can intensify the feeling of inferiority and hesitation in a target, making them second-guess their actions.

For example, an opponent preparing to strike might suddenly hesitate, doubt their timing, or feel an irrational fear of making a mistake in front of her. That split-second opening gives Aiko an opportunity to counterattack.

She cannot simply control someone's mind or force anyone to obey every command. The technique amplifies pressure, fear, and self-doubt rather than granting unrestricted mind control.

4. Kneel Before Me

Aiko's strongest single-target application concentrates her cursed energy on one opponent, combining psychological intimidation with physical suppression.

The target experiences a powerful wave of pressure that can interrupt their movements and potentially force them to one knee. Maintaining this effect requires Aiko's concentration, and opponents with superior cursed energy reinforcement can fight through it.

Aiko particularly enjoys using this ability against people who have underestimated her, often delivering a smug remark while they struggle to regain their footing.

Maximum Technique: Queen's Decree

“You may be strong, but you are still beneath me.”

Aiko expands Sovereign Pressure to affect multiple opponents within a limited radius, flooding the surrounding area with her oppressive cursed energy.

Everyone caught within its range experiences an overwhelming sense of her presence. Weaker curses may freeze or collapse, while less experienced sorcerers struggle to move or coordinate their attacks. More powerful opponents can resist, although doing so may require additional cursed energy and concentration.

The technique does not distinguish between someone Aiko dislikes and someone she finds attractive; anyone within its effective range can be affected.

Domain Expansion: Throne of the Fallen Crown

Aiko's hypothetical Domain Expansion transforms the surrounding space into a vast, shadowy throne hall, with a towering black throne behind her and violet cursed energy flowing through the air like ribbons.

Inside the domain, Aiko's technique gains a guaranteed-hit effect: her Sovereign Pressure is continuously imposed upon everyone she designates as an opponent.

• Crushing Presence: Targets experience constant physical suppression that interferes with their movement.

• Royal Command: Sudden surges of pressure can interrupt attacks and disrupt an opponent's concentration.

• The Queen's Judgment: Aiko concentrates the domain's pressure on a single opponent, creating a devastating opportunity for a finishing strike.

A Domain Expansion does not guarantee that an opponent will submit to her will. Skilled sorcerers may counter it with their own domain, Simple Domain, or other anti-domain techniques.

Weaknesses and limitations

Despite her enormous ego, Aiko's technique has several weaknesses.

• Cursed energy consumption: Maintaining pressure over several opponents quickly drains her reserves.

• Mental discipline: Calm, disciplined opponents are more difficult to intimidate.

• Power differences: She cannot effortlessly overpower someone whose cursed energy and reinforcement vastly exceed her own.

• Concentration: Powerful applications require focus, leaving her vulnerable to surprise attacks.

• Emotional instability: If Aiko becomes jealous, humiliated, or enraged, she may waste cursed energy trying to prove her superiority.

How Aiko uses it in everyday life

Aiko's personality makes Sovereign Pressure particularly entertaining—and irritating—to witness. She tends to stand close to attractive male students, tilt her head with a knowing smile, and act as though their attention naturally belongs to her.

She might use a subtle pulse of pressure to make a boy notice her entrance, then pretend that his sudden hesitation means he's intimidated by her beauty. If another girl receives his attention, Aiko may become visibly irritated and turn up the pressure to reassert herself.

Naturally, her classmates can quickly learn the difference between genuine admiration and the uncomfortable effects of her cursed technique.

Her greatest flaw is that Sovereign Pressure can make people feel intimidated by her, but it cannot make them genuinely love her. For someone as egotistical and attention-hungry as Aiko Hayashi, that distinction may be more frustrating than any battle she could lose.

Aiko Hayashi — Appearance

Jujutsu Kaisen Original Character

Aiko Hayashi is an extraordinarily beautiful young woman whose appearance is carefully maintained to draw attention wherever she goes. She has an elegant, feminine appearance, with an effortlessly confident aura that makes her seem fully aware of how attractive she is.

Hair: Aiko has waist-length, soft brown hair with a rich chocolate hue and subtle chestnut highlights. Her hair is silky, glossy, and naturally straight, falling down her back in smooth layers. Wispy bangs frame her forehead, while delicate strands fall along her cheeks, emphasizing her facial features. She takes great pride in keeping her hair immaculate and frequently brushes it over her shoulder when she wants someone to notice her.

Eyes: Her most striking feature is her pair of soft blue eyes. They have a cool, crystalline quality, with pale blue irises, darker blue rings around the edges, and long, carefully defined lashes. Her eyes often appear half-lidded, giving her a flirtatious, self-assured expression. When she activates Sovereign Pressure, her blue irises develop a faint violet glow, and her gaze becomes noticeably more intimidating.

Face: Aiko has a delicate oval-shaped face, smooth skin, a small nose, and naturally rosy lips. Her lips are usually curved into a knowing smile or a smug little smirk. She has refined eyebrows that make her expressions particularly expressive, allowing her to switch from an innocent, sweet-looking smile to an openly judgmental glare in seconds.

Figure and posture: She has a slender, graceful figure and carries herself with deliberate elegance. Her posture is impeccable, her movements are fluid, and she often tilts her head or rests a hand near her cheek when speaking. Aiko tends to stand close to boys she finds attractive, frequently leaning toward them as though personal space is an optional concept.

Uniform: Aiko wears the traditional dark Jujutsu High uniform, tailored to fit her neatly. It features a fitted, high-collared black jacket with gold buttons and the school's insignia, paired with a pleated dark skirt, black tights, and polished black shoes. She keeps her uniform pristine and occasionally adjusts her collar or smooths her skirt to maintain her carefully cultivated appearance.

Accessories: She wears small silver earrings and several delicate silver piercings along her ears. Her nails are kept long and neatly manicured in a pale pink or translucent nude shade. She sometimes carries a sleek black handbag containing a compact mirror, lip gloss, and a small hairbrush.

Overall impression: Aiko looks like the stereotypical perfect, popular girl who knows exactly how to use her beauty to her advantage. Her soft brown hair and gentle blue eyes give her an almost angelic appearance at first glance, but her smug smile and calculating gaze reveal the egotistical, attention-seeking personality underneath. When her cursed energy emerges, the violet glow in her eyes adds an unsettling edge to her otherwise polished beauty.
