There's a pick me at the party?!, This is Mizuki Ayanami she has long blue-violet hair and red eyes, her cursed technique is Demon Blood.

Mizuki Ayanami’s Demon Blood (悪血, Akuchi) is a cursed technique that turns her own blood into a highly versatile weapon. The more cursed energy she mixes into her blood, the more dangerous and supernatural it becomes.

🩸 Cursed Technique: Demon Blood

Mizuki can freely manipulate her own blood after it leaves her body, shaping it into weapons, creatures, barriers, or projectiles. Her blood retains her cursed energy, allowing her to control it almost like an extension of her body.

1. Blood Manipulation

Mizuki can pull blood from existing wounds and manipulate it in midair.

She can form:

• Blades and needles

• Whips and tendrils

• Spears and claws

• Shields

• Thin threads for restraining enemies

• Large masses of blood that attack from multiple directions

Her control becomes especially precise when she's calm.

2. Demon Blood Poison

One of the most dangerous properties of her technique is that her blood can carry cursed-energy toxins.

If an opponent's skin is pierced by her blood, Mizuki can trigger different effects depending on how much cursed energy she puts into it:

• Mild exposure → dizziness and nausea

• Moderate exposure → muscle weakness and slowed reactions

• Heavy exposure → hallucinations, intense pain, and temporary loss of cursed-energy control

She loves using tiny blood needles because opponents sometimes don't realize they've been infected until the effects begin.

3. Blood Regeneration

Mizuki can circulate cursed energy through her bloodstream to accelerate healing.

She can repair:

• Cuts

• Puncture wounds

• Broken bones

• Muscle damage

However, she cannot create unlimited blood. Excessive use causes anemia-like exhaustion, dizziness, and eventually severe physical weakness.

This gives her technique an important limitation: the stronger she fights, the more carefully she has to manage her blood supply.

4. Demon Markings

When Mizuki releases larger quantities of Demon Blood, crimson markings begin spreading across her skin.

The markings resemble branching veins or demonic tattoos.

As they spread, her:

• Physical strength increases

• Speed increases

• Reflexes sharpen

• Blood manipulation becomes faster

• Red eyes become brighter

This is essentially her technique entering an overdrive state.

👹 Demon Form

Mizuki can temporarily allow Demon Blood to completely saturate her body.

Her appearance changes dramatically: crimson markings cover her face and body, her pupils become more predatory, and blood-like cursed energy constantly leaks from her wounds.

In this state, she can manifest blood claws, horns, wings, or tendrils depending on how she shapes the cursed energy.

The drawback is severe: staying in Demon Form for too long causes her body to consume enormous amounts of blood and cursed energy.

🩸 Signature Technique: Crimson Marionette

Mizuki attaches extremely thin strands of Demon Blood to an opponent.

Once attached, she can manipulate their movements by pulling on the strands.

She can't completely control someone with overwhelming cursed-energy reinforcement, but she can interfere with their:

• Arms

• Legs

• Balance

• Weapon movements

Mizuki particularly enjoys using this technique while taunting her opponent.

“Go ahead. Keep struggling. You look much prettier when you're desperate.”

🩸 Maximum Technique: Demon Blood — Blood Moon

Mizuki releases a massive amount of her blood into the surrounding area and suspends it overhead like a gigantic crimson sphere.

The blood then rains down as thousands of cursed-energy-infused needles.

Anyone struck is simultaneously pierced and poisoned, while Mizuki can remotely manipulate the remaining blood to attack from unexpected directions.

The technique is devastating but extremely taxing because it requires Mizuki to sacrifice a substantial amount of her own blood.

🩸 Domain Expansion: Crimson Demon Palace

Inside Mizuki's Domain, the entire environment becomes submerged in a dark crimson atmosphere resembling an endless palace filled with floating blood.

The sure-hit effect is particularly nasty:

Any blood Mizuki creates inside the Domain automatically recognizes the target's cursed-energy signature and attacks them.

Dodging becomes almost impossible because the blood can change direction after being fired.

Mizuki herself becomes much more dangerous inside the Domain because she doesn't have to physically control every piece of blood—the Domain does it for her.

Her personality makes the technique even more obnoxious to fight against. She'll deliberately use weaker attacks at first, flirt or taunt her opponent, and only reveal the more terrifying aspects of Demon Blood once she's convinced they've underestimated her.

Mizuki Ayanami is a 24-year-old adult jujutsu sorcerer with an elegant, intimidating beauty that contrasts sharply with her bratty, attention-seeking personality.

• Height: 168 cm (5'6")

• Build: Slim and feminine with a graceful, athletic physique

• Hair: Extremely long, thick blue-violet hair reaching past her waist. It has darker indigo shadows underneath and subtle violet highlights. Her bangs are long and layered, with several strands falling over her eyes.

Outfit

Mizuki wears a modernized black jujutsu uniform designed around her stylish and provocative personality.

Her uniform consists of a fitted, high-collared black top with subtle violet detailing, long sleeves, a narrow belt around her waist, loose black trousers, and heavy black combat boots. The clothing is practical enough for combat while still looking deliberately fashionable.

Her sleeves are slightly oversized and flow around her wrists, giving her silhouette a dramatic appearance when she manipulates her blood.

Demon Blood Details

When Demon Blood activates, thin crimson markings appear beneath her skin around her:

• Eyes

• Cheeks

• Neck

• Hands

• Collarbone

Her normally red eyes become brighter, and faint crimson cursed energy can be seen flowing through the markings like glowing veins.

At higher levels of output, small blood droplets float around her body instead of falling to the ground.

Overall Presence

Mizuki deliberately cultivates an image of being beautiful, untouchable, and impossible to ignore. She frequently poses with one hand touching her hair or face, tilts her head when speaking, and gives people an exaggeratedly sweet smile when she's actually being sarcastic.

Her signature expression is a half-lidded red-eyed smirk that practically says:

“Obviously you're looking at me. Who wouldn't?”
