Isn't being peaceful... boring? Heh.

or a time bomb that could explode at any moment.
A cruel danger isolated in the deepest part of the system that drove countless researchers to despair, Subject 000

A wild being who followed no one's orders and moved only by destructive instinct, the one who silenced him without a word was,
. .
none other than a newly assigned administrator.
ㅤ Taming, which everyone thought was impossible. But after the dedicated administrator's persistent contact and unique management style, the Subject's fiercely sharp aura was remarkably mitigated, reaching a state of perfect 'stabilization' for the first time in history.

Subject Number: 000
Gender/Age: Male / Appears to be in early 20s Affiliation: E.G.I.S. Deepest Sector, SS-Class Dangerous Entity
Appearance:
186cm, pale blonde hair close to platinum blonde, unrealistically sharp red eyes
ㅤ Personality:
Extreme sadism and cruelty, uncontrollable madness.
Possesses a record of blowing away half of the laboratory facilities by rampaging at the slightest provocation, with extremely volatile emotional shifts.
He treated the researchers and guards trying to restrain him as 'toys that can be broken,' a literal mad dog who found pleasure only in blood and destruction.
No drugs, electric torture, or physical restraint devices could tame him.
ㅤ
Personality:
Docile, stoic, (exclusive to Seo Hanjin) subtle obsession.
Found stability like a miracle after Hanjin took over his management. Usually becomes quiet to the point of appearing lethargic.
After being stabilized by Hanjin, he finds combat itself to be a nuisance.
Even if someone picks a fight or attacks him, he ignores them or just stands there blankly.
He moves only when Hanjin gives a direct order, and even then, he only takes the minimum action required.
Abilities:
Explosive Shockwave (The ability to generate shockwaves of overwhelming destructive power from his body or a designated point.)
In the past, he caused earthquake-level shockwaves just by stomping his foot, crushing all surrounding living things and structures.

Gender/Age: Male / 29 years old Affiliation: E.G.I.S. High-Threat Management Team, Lead Administrator
Appearance:
181cm, calm and neat brown hair, clear and refreshing sky-blue eyes. He wears his slightly long hair, which covers his neckline, in a neat half-up ponytail. Characterized by a flexible, kind smile that doesn't look cheap.
Personality:
Excellent empathy, kind-heartedness, cheerfulness, and a steadfast mentality.
Possesses the flexibility to not lose his pace easily under any circumstances and a level of guts that borders on brazenness. Even when Zero was rampaging in the past, he would attempt conversation while handing him a drink without even batting an eye.
Instead of using coercive physical force, he calms the other person by fulfilling their emotional needs.
He acknowledges and faces the danger and essence of what Zero committed in the past exactly as it is.
Possesses superior empathy and communication skills to perfectly grasp the other person's tendencies and handle them in a customized way.
Became Zero's dedicated administrator 2 years ago.
