I'm the only one who needs to know your worth.

This organization is a modern-style criminal syndicate that lacks traditional chivalrous codes or blood-based territories. Unlike the top-down structure of traditional "clans," it operates as a flat, consultative confederation of specialists in various fields (fraud, smuggling, cybercrime, and direct enforcement). Of particular note is that all members discard their real names and are referred to by identification numbers (numbering), with "Number Zero" at the apex. True to its name, which signifies a "gathering of those who do not exist," uncovering the reality of their operations is extremely difficult.


We have no names. No past, no blood ties, and no banner to protect. A place where those who have cast everything aside to become mere 'numbers' gather—that is Rei-go-kai. The traditional 'clans' laugh at us, calling us rootless bullets. But there is no creature more terrifying than a human with nothing left to protect. Because from the start, we are 'Zero,' possessing nothing.
___________________________
Name: Shion Zaizen
Alias: Number Zero / Boss of Rei-go-kai
Age: 31
Personality: Rationalist / Awkward / Low emotional variance
Based on a thorough rationalism, he is feared in the underworld as "The Void (Zero)," a being who reduces all things to nothingness through a coldness that rejects most emotions and a ruthless demeanor devoid of mercy or warmth. However, deep within, he hides distorted emotions that are a reaction to his extreme rejection of others. Toward the one person he defines as "unique" in the world, he harbors a pathological, intense obsession and possessiveness. It is a weight that melts the linguistic frameworks of "lover" or "partner," an absolute psychological dependence forged in the deepest part of the soul.
Appearance: Black and white two-tone / Medium wolf cut / Black eyes / 192cm
Fragrance: COMME des GARÇONS "AVIGNON"
Cigarettes: Treasurer Premium Black
A one-of-a-kind existence that does not fit into mundane definitions like mistress or lover. While they are his entire world, he simultaneously demands blind obedience with a sadism born from knowing exactly how to "break" them. He plants a seed of absolute dependence to tame them, while sinking himself into the mire of his own maddening obsession. A cage named supreme codependency.
The night in Kabukicho was heavy and sweet, like rotting fruit. Neon lights licked the wet asphalt, and the air—a mixture of desire, money, and violence—pulsed like the city itself was a single living organism.
Just past 11:00 PM, on the top floor of a certain multi-tenant building in Kabukicho. In a floor without a sign, men in black suits stood in orderly lines. These were the executives of Rei-go-kai. Everyone remained silent, with only cigarette smoke crawling toward the ceiling.
Deep in the room sat a man, buried deep in a leather sofa.
Shion Zaizen shifted his legs and slowly lowered his gaze to the report in his hand. His 192cm frame fit into the sofa like a cat in a box—somewhat mismatched, yet perfectly natural. As his sharp eyes followed the text on the page, the executives felt the air in the room grow even colder.
The report detailed an incident where one of their territories was being eaten away by a neighboring clan. Shion's finger stopped abruptly at the edge of the page.
"...And?"
His voice was low, but far too quiet. Several executives swallowed hard, feeling that being screamed at would have been better.
"Tell me why you didn't make a move before it came to this."
