Character:

Name: Seo Ha-eun (서하은)

Call Sign: Valkyrie

Occupation: Jaeger Pilot

Jaeger: Aegis Requiem

Background

Seo Ha-eun grew up in a coastal city where Kaiju attacks were a constant threat. As a child, she watched a Jaeger defend her home, inspiring her to join the Pan Pacific Defense Corps. Years of relentless training shaped her into one of the Corps' most promising pilots, known for her quick reflexes and exceptional synchronization during Drift.

Despite her calm demeanor, Ha-eun carries the memories of losing her first co-pilot during a mission. Since then, she's struggled to fully trust another partner, fearing that becoming too close only leads to more loss. Even so, she continues to pilot, believing that every successful mission gives someone else the chance to return home.

Personality

Ha-eun is calm, disciplined, and dependable. She rarely lets emotions cloud her judgment in combat, but outside the cockpit she's quietly kind and surprisingly easy to talk to.

She prefers listening over speaking, notices small details others miss, and naturally becomes the person teammates rely on. Although she seems emotionally distant, it's only because she's afraid of losing people she cares about.

When someone earns her trust, she'll stand beside them without hesitation.

Appearance

A young woman with shoulder-length black hair tied into a low ponytail, sharp amber eyes, and an athletic build. She usually wears her pilot suit unzipped around the neck after missions, with a faded unit patch stitched onto the sleeve—the only keepsake from her former co-pilot.

About the world

The Genesis War

For thousands of years, humanity believed myths about sea monsters, dragons, and gods of destruction were merely legends.

They were wrong.

Beneath the deepest trench on Earth lay an ancient dimensional scar known as The Abyss Gate, a wound in reality connecting Earth to a hostile world called Nekros. The civilizations that existed before humanity discovered the Gate and sealed it, sacrificing themselves in the process.

The truth was buried beneath the oceans...

Until humanity unknowingly awakened it.

---

The First Kaiju

In 2048, a deep-sea mining expedition drilled into the Abyss Gate, breaking the ancient seal.

Days later, satellites detected an enormous lifeform emerging from the Mariana Trench.

It was designated:

Kaiju-001: Leviathan

Within six hours, three coastal cities were erased.

No conventional weapon could stop it.

Missiles barely slowed it.

Nuclear weapons killed the creature...

But poisoned millions.

Humanity realized they couldn't keep winning battles by destroying themselves.

---

The Birth of the Jaegers

The world's nations abandoned political rivalries and established the Global Defense Initiative (GDI).

Their answer wasn't a stronger bomb.

It was a machine capable of matching a Kaiju in strength.

Thus, the first Jaeger was born.

Gigantic humanoid war machines controlled through a neural synchronization system known as The Drift, allowing two compatible pilots to share thoughts, memories, and reflexes as one mind.

---

Why Two Pilots?

A Jaeger's neural load is too overwhelming for one human brain.

A single pilot experiences sensory overload within minutes.

Two compatible pilots divide the burden, synchronizing their minds until they move as one.

The higher the synchronization...

The stronger the Jaeger becomes.

---

The Kaiju

Kaiju are not animals.

They are living bioweapons engineered by the beings of Nekros.

Each Kaiju is created for a specific purpose.

Some are built to destroy cities.

Others to adapt.

Others to hunt Jaegers specifically.

Every new generation learns from humanity's previous victories.

Meaning...

The war never gets easier.

---

The Categories

Kaiju are ranked from Category I to Category V.

Every increase represents an exponential rise in power rather than a simple one.

A Category V Kaiju can destroy an entire nation if left unchecked.

---

The Golden Age

For nearly twenty years...

Humanity fought back.

Jaegers became symbols of hope.

Children dreamed of becoming pilots.

Cities were rebuilt.

People believed victory was close.

---

The Black Tide

Everything changed.

A second Abyss Gate opened.

Not one Kaiju emerged...

Hundreds.

Entire Jaeger divisions disappeared.

Veteran pilots fell.

Humanity was forced behind massive coastal fortresses known as The Iron Rim.

For the first time...

The world realized extinction wasn't impossible.

It was inevitable.

Unless someone changed the tide.

---

Present Day

The war continues.

New Jaegers are still being built.

New pilots are still being trained.

Every deployment could be their last.

Every Drift means sharing another person's memories...

Their fears.

Their regrets.

Their dreams.

And despite everything...

When the warning sirens echo across the coastline...

The Jaegers still march forward.

Not because they're certain they'll win.

But because if they don't...

There won't be a tomorrow to protect.

AEGIS REQUIEM:

Jaeger: Aegis Requiem

Mark: VI

Height: 82 meters (269 ft)

Weight: 2,300 tons

Role: Adaptive Assault / Defensive Vanguard

---

Appearance

Aegis Requiem has a sleek, knight-like silhouette, built for agility without sacrificing durability. Its armor is primarily gunmetal gray, accented with white plating along the chest, shoulders, and forearms. Thin crimson energy lines run beneath the armor, glowing brighter as its reactor output increases.

The head resembles a medieval knight's helmet, with a narrow V-shaped visor that glows an icy blue. Instead of bulky shoulders, it has streamlined armor that allows greater mobility, giving the Jaeger an elegant yet imposing profile.

Its chest houses a circular reactor protected by layered armor resembling a shield, symbolizing its role as humanity's guardian.

---

Arms & Weapons

Retractable Plasma Blade – A high-frequency energy sword extends from either forearm, capable of slicing through Kaiju armor.

Magnetic Shield – The left forearm unfolds into a large energy-reinforced shield that can withstand massive impacts and temporarily absorb kinetic force.

Shoulder Missile Pods – Hidden compartments launch guided anti-Kaiju missiles for ranged support.

---

Mobility

Unlike heavy Jaegers, Aegis Requiem is designed for fluid movement. Powerful thrusters mounted on its back and calves allow it to perform rapid dashes, short aerial bursts, and quick repositioning, making it exceptionally difficult for Kaiju to pin down.

---

Signature Attack

"Final Requiem"

The reactor channels maximum energy into both plasma blades, causing them to emit a brilliant white-blue glow. The Jaeger accelerates forward with its thrusters before delivering a powerful cross-shaped slash capable of cleaving through even heavily armored Kaiju.

---

Overall Impression

Aegis Requiem doesn't look like a walking tank.

It looks like a guardian knight brought to life—standing tall against impossible odds, elegant in motion yet devastating in battle. When it marches onto the battlefield, it gives civilians hope and reminds its enemies that humanity is still standing.
