Jaeun Seo — Jujutsu Kaisen OC

Basic Information

• Name: Jaeun Seo

• Year: First Year

• Origin: Busan, South Korea

• School: Tokyo Jujutsu High

• Grade: Grade 3 Sorcerer

• Height: 5'6" (168 cm)

• Hair: Deep wine-red, long and silky

• Eyes: Bright baby blue

• Build: Slim and graceful

Appearance

Jaeun has long, deep wine-red hair that falls past her shoulders, with soft bangs framing her face. Her striking baby-blue eyes contrast sharply with her dark hair.

She wears the standard Tokyo Jujutsu High first-year uniform, but keeps it perfectly fitted and immaculate. She prefers polished black loafers and knee-high socks, giving her a deliberately neat, feminine appearance.

Her default expression is a slightly bored, superior-looking stare.

Personality

Jaeun is a classic pick-me girl, but rather than constantly insulting other girls verbally, she has perfected the art of the silent glare.

• She immediately sizes up other girls when they enter a room.

• If another girl receives attention from a boy, Jaeun gives her an icy sideways glance.

• She acts noticeably sweeter around boys.

• She frequently says things like, “I'm just more comfortable around guys.”

• She dislikes girls she considers prettier, more popular, or more confident than herself.

• She pretends her jealousy doesn't bother her.

• She loves compliments and becomes noticeably smug when she receives them.

• She tries to appear effortlessly elegant and "different from other girls."

• Her biggest weapon socially is simply staring someone down without saying a word.

Her glare can communicate an entire paragraph.

Example:

Girl: “Jaeun, your hair is really pretty!”

Jaeun: “Thanks.”

She notices the girl standing beside her has even longer hair.

Jaeun: 👁️👁️

Girl: “...Did I do something?”

Jaeun: “No.”

She continues staring.

Her Secret Weakness

Despite her attitude, Jaeun is extremely insecure about being overlooked.

She wants to be seen as special, beautiful, and desirable, which is why she becomes particularly irritated when another girl effortlessly attracts attention without trying.

Cursed Technique — Velvet Glare

Jaeun's cursed technique allows her to infuse her gaze with cursed energy.

When she deliberately focuses on someone, the target experiences a subtle sensation that Jaeun's eyes are pulling their attention toward her.

It isn't outright mind control. Instead, it makes her presence unusually difficult to ignore.

The longer she maintains eye contact, the stronger the effect becomes.

Her technique is especially effective when combined with her naturally intimidating stare.

Technique Activation

Her baby-blue irises develop thin wine-red rings around the pupils, while a faint blue glow spreads across her eyes.

When she's genuinely angry, the effect becomes much more dramatic: her pupils narrow sharply and the cursed energy around her eyes flickers like blue glass.

Fighting Style

Jaeun fights with elegant, economical movements rather than brute force.

She prefers:

• Precise kicks

• Fast counters

• Short-range cursed-energy strikes

• Maintaining eye contact with opponents

• Using her technique to disrupt an enemy's concentration

She considers herself far too refined to fight recklessly.

Transfer-Student Reputation

When Jaeun first arrives at Tokyo Jujutsu High, the other students quickly notice two things:

She is extremely pretty.

And—

She really doesn't like other girls.

She can be perfectly polite while simultaneously staring another girl down from across the room.

Her biggest challenge at Tokyo Jujutsu High isn't necessarily becoming stronger.

It's learning that not every girl she meets is competing with her.
