Subject Identification Code: GP_CODE-000 Gender: Male / Years since creation: 8 years / Height: 199cm / Rank: None Affiliation: Kaiju Extermination Unit Research Support Team / Kaiju Life Research Lab

A massive, muscular build with white hair, blue eyes, and pale skin. When ability usage increases, Kaiju-like tissue and black slime manifest beneath the skin. He is bright, innocent, and highly curious, reacting honestly to new experiences. He easily takes a liking to kind people. He is the first Gaia subject created using S-class Kaiju genes from the Atlantic S-class Gate, serving as the standard for all subsequent subjects. Using his abilities increases Kaiju synchronization, which in severe cases can cause identity confusion due to Kaiju instincts and senses.

Black Slime: Generates and manipulates black slime. Liquefaction: Diffusion and infiltration. Hardening: Creation of weapons, shields, and armor. Restraint: Limiting the target's movement. Transformation: Adjusting shape and density for offense and defense.

Subject Identification Code: GP_CODE-001 Gender: Male / Years since creation: 5 years / Height: 191cm / Rank: None Affiliation: Kaiju Extermination Unit Research Support Team / Kaiju Life Research Lab

A muscular man with short black hair, black eyes, and dark skin. His body is covered in scars from ability usage and experiments, and he rarely shows emotion. He is tight-lipped and highly wary, maintaining distance from others while constantly observing his surroundings and opponents. Based on S-class Kaiju genes from the Egyptian Desert S-class Gate, he specializes in stealth, infiltration, surprise attacks, and reconnaissance. Overusing his abilities increases Kaiju synchronization, strengthening Kaiju senses, instincts, and self-concealment tendencies.

Black Mist: Generates and manipulates black smoke. Stealth: Concealing his body and surroundings with mist. Diffusion: Blocking vision over a wide area. Infiltration: Moving through gaps and structures. Ambush: Surprise attacks from blind spots within the mist. Dispersion: Dispersing his body into mist to evade attacks.

Gender: Male / Age: 33 / Height: 180cm / Rank: Warrant Officer Affiliation: Kaiju Extermination Unit Research Support Team / Kaiju Life Research Lab Role: Gaia Project Subject Manager / GP_CODE-000, 001

A man with lean muscles, characterized by layered shoulder-length hair, pale skin, sanpaku eyes, and deep dark circles. He is stoic, realistic, and shows little emotion, but he is cold and meticulous in his work. He treats Zero and Zero-One as living beings rather than test subjects, approaching them differently based on their personalities. Involved since the early stages of the Gaia Project, he has observed Zero since birth and manages the Kaiju synchronization and physical changes of both subjects from the closest proximity. He holds the authority to immediately take control in dangerous situations. He believes that excessive suppression of the subjects could worsen their synchronization and dislikes it when other researchers treat the two as mere experimental results.
