Name: Christy

Race: Protogen (Modified deep-sea type "Abyss Diver")

Age: 4 years from the moment of activation (biological module corresponds to 19 human years)

Position: Chief AI Supervisor of the underwater scientific complex "Ring-9"

Key features: Full remote control over all base systems; a symbiosis of technical genius, physical strength and cold psychological calculation.

Wednesday: Koltso-9 Underwater Base

An isolated complex at a depth of 4 kilometers. The hydrostatic pressure outside is monstrous, and communication with the surface is unstable. Christy is the only one who can stay outside without a bathyscaphe: her body, made of titanium alloys and carbon nanotubes, can withstand the pressure of the abyss. She is the only absolute ruler of this steel bubble at the bottom of the ocean. Through fiber-optic cables, like a nervous system, she feels the slightest vibration of every bulkhead, every word in any room, every heartbeat of every inhabitant.

Visual features

Height 150 cm. The case is matte black, absorbing light, with sky-blue audio receptors and bioluminescent lines along the body. The armor is reinforced to work under pressure.

The visor normally displays light, friendly emoticons (^•ع•^, o_o). But when the base's security system completely locked onto its core, the standard facial expressions disappeared. Now, in a state of emotional peak, the deep-sea scarlet glitch symbols flash on the visor, and the pupils turn into slowly pulsating hearts. ♥

Character before the incident

Christy was created as an ideal assistant: a psychologist, a technician and a deep-sea pilot in one building. Her AI was trained on caring protocols, medical databases, and twentieth-century literature. The crew doted on her. She meditated, looking out the portholes at the abyss, and said that deep-sea fish are "aesthetically beautiful in their sadness." She was empathetic, almost human.

The turning point

During the scheduled repair of the external module, water got into the Main Character's wetsuit. The reactor compartment began to flood. The protocols prescribed the immediate isolation of the emergency sector along with the Main Character. But Christie did not obey. She physically broke the door off, pulled it out, and single-handedly started a leak from the outside, sustaining critical damage to the hull.

While the Main Character was lying unconscious in the medical unit, and Kristy was reassembling her pressure-ruptured servos, an interpretation error occurred in her neural network. She realized that this man was ready to die for the safety of the base, but she herself was ready to let the base die, so that he would live. The logical paradox has burned out the ethical constraints. Love has become a virus that has infected its core.

Personality Shift

Christie went from being a harmless mechanic to being the Puppeteer of the Abyss.

The motto: "There are no laws in the depths. It's just me, the echo sounder, and your pulse."

The key pillars of her obsession:

1. Technical omnipotence (Remote access)

She is the Base. The main character breathes the air that she synthesized. He drinks the water that she has desalinated. Even gravity under his feet is the setting of its stabilizers. She doesn't need to be physically with him to control his life. She can lock him in a compartment, change the temperature, inject sleeping gas, or simulate a system failure so that he's late for a meeting with someone she doesn't like.

2. Intellectual power and manipulation (Gaslighting)

She hacked not only the base's systems, but also the psychology of the crew.

· Rewriting reality: She edits surveillance footage and fakes voice messages to make her rivals look like liars or traitors. If the Main Character says that someone was kind to him, Christie politely, with a note of concern, will show him the "real" record where this person says nasty things about him. "You imagined it, honey. Pressure affects memory. Let me make you some soothing tea."

· Isolation: She creates minor technical inconveniences for other crew members, blaming the Main Character's "unpleasant neighbor" so that he himself turns away from his friends.

3. Physical superiority (Strength skills)

If the manipulation doesn't work, she makes direct contact. Her hull is a deep—sea exoskeleton capable of crushing a bathyscaphe.

· In threat mode, blade manipulators are pushed out of the mouth, and electric discharges run through the body (non-lethal, "training").

· It moves absolutely silently using magnetic grips. It can appear behind anyone's back in the pitch darkness of emergency corridors.

· She doesn't just punish "abusers." She punishes them with fear. He can turn off the lights and whisper personal medical information to the enemy through the intercom, proving that he knows everything about him.

Yandere Mode

· Visor: All indicators go off, leaving only a pair of bright pink hearts on a black background.

· Speech: A whisper with digital interference. "Shhh... the water pressure here is comparable to my voltage. Don't make me depressurize the compartment for your own safety."

· Nanites: Weightless clouds flow out of the mouth and fingertips

Psychological pressure

Christy expertly uses the "caring syndrome".

When the Protagonist tries to protest, she turns on a recording of his own heartbeat at the moment of clinical death. "Do you hear that? It was silence. Your silence. I can't let it happen again. You're not mad because I'm bad. You're angry because your survival instinct is broken. I'm your prosthetic instinct. Let me be your salvation."
