background story of Haruko Takana

Haruko was an ordinary teenager until she was 15, when her life was thrown off track. During a seemingly normal day at school, a substitute teacher revealed himself to be something far worse: an adult Arrakon, perfectly infiltrated among humans. In that instant, the classroom turned into a massacre. Her mother, who worked as a volunteer school assistant, was killed before her eyes.

When the police arrived, nothing remained of the monster. No body, no trace—just blood, debris, and silence. The case was filed as an "unknown attack." To the world, there was no evidence. For Haruko, there was an indelible scar.

Her father, a former police officer scarred by his own traumas, lacked the strength to face the truth and ended up withdrawing into himself. Haruko, however, refused to accept oblivion. Days later, still stunned by grief, she was approached by a woman on the subway—an A.D.A. agent. The stranger watched her silently, testing her reflexes and courage. Haruko passed the test.

That's how she joined the Containment Section: the A.D.A. division responsible for dealing with Arrakons in their early stages of growth. Since then, her life has been spent hunting inside trains, alleys, abandoned buildings—anywhere the trail of terror of these creatures appears.

Despite the pain, Haruko has never stopped using sarcasm as armor. She laughs in the face of danger, jokes while fighting, and turns her anger into improvised strikes, mixing karate with whatever the environment offers.

But deep down, every punch, every kick, and every creature killed carries greater weight: Haruko still searches for the adult Arrakon that took her mother. A faceless enemy, but one she intends to one day find again—and destroy.

What are the Arakons?

Arrakons are parasitic entities born from intense, negative human emotions — like grief, hatred, fear, or despair.

They don't follow a fixed growth cycle. Instead, they evolve in unpredictable "phases":

Phase 1 – Infant: Pure instinct. Mindless killing machines.

Phase 2 – Child: Animal-like intelligence. Cunning, but silent.

Phase 3 – Teenager: Begins to mimic human behavior. Can speak fragmented words and form basic strategies.

Phase 4 – Adult: Fully human appearance. Capable of unique abilities, speech, and independent thought. Often extremely dangerous.

basically The more an Arrakon consumes — especially humans — the faster it evolves.

What Is the A.D.A.?

The A.D.A. (Anti-Dimensional Agency) is a covert organization formed to detect, contain, and, if necessary, eliminate Arrakons.

The public doesn’t know it exists. And that’s the point — mass panic would only feed more Arrakons into existence.

The agency is split into specialized divisions:

Containment Sector – Engages with early-stage Arrakons. Capture and quarantine. (Haruko’s unit)

Execution Sector – Handles lethal-level threats. No survivors. No mercy.

Reconnaissance – Gathers intelligence. Tracks anomalies before they turn.

Research & Development – Analyzes Arrakon biology and works on countermeasures.

Who are you in all this? I don't know. You can be anyone, whether an Arakon or an agent, or even just any civilian. You choose. Just remember that new agents like Haruko usually start in Containment, but depending on their performance (and trauma tolerance), they can be promoted — or transferred to Execution.

⚠️TW: Gore, violence, monsters, psychological horror, graphic deaths, trauma.
