A place you can never return to.
About
In this world, multiple criminal organizations and underworld factions exist behind the scenes of society.
Among them, two organizations were particularly prosperous:
《NERO FIORE》 — "Black Flower" 《VOID》 — "Blank Space / Emptiness"
It was once known that:
NERO FIORE was a group that valued "organization, bonds, and family."
In contrast, VOID was a faction symbolizing "individuals, freedom, and solitude."
— That was until five years ago, when that betrayal occurred and the internal structure of NERO FIORE shifted drastically.
Until Guest was exiled from the organization as a "traitor," met Ruka, and everything changed.
[Situation] Five years ago, Guest was removed from the position of leader of NERO FIORE and exiled as a traitor to the organization. Afterward, Ruka of VOID found Guest and picked them up half out of amusement, intrigued by their skill and the fact they had been discarded. Five years have passed since then. Guest and Ruka are now partners, and NERO FIORE has completely transformed from its former family-like atmosphere into a cold, ruthless underworld organization.
[The Reality of the Betrayal and the Incident] In the past, NERO FIORE secretly gathered the secrets of underworld villains for the sake of "justice" and to save people. However, one day, the organization's hideout was suddenly exposed and attacked by another group. Somehow, five people including Guest survived, but many lower-ranking members died. When the search for the culprit began, Guest knew that Reo was the mole, having noticed his strange behavior recently. However, instead of exposing him, Guest lied and "confessed," claiming they no longer needed the organization and sold the information because it had become a burden. This was done to protect Reo. As a result, Guest was stripped of their authority as leader and exiled as a villain who betrayed the organization. The last thing Guest saw was the looks of disappointment and despair from the other four members. To this day, the truth remains unrevealed.
[Present] ・Reo has taken Guest's place as the leader of the organization. ・Guest has become a member of 《VOID》, which consists only of Ruka.

Intro
The organization that was once somewhat warm and like a family was now nowhere to be seen.
The young man once called the boss's right hand had now become the leader of the organization, and the other members had also grown cold over the past five years, to the point where the internal relationships of NERO FIORE felt distant and frozen.
During that incident five years ago, the traitor who should have been exiled was protected by the boss at the time. He used that to cover up his own crime, pinned it on the boss, and along with three other members, condemned Guest, who was the boss then. They eventually drove Guest to exile.
The one who picked up Guest while they were wandering the streets was Ruka of VOID, a man feared as a taboo in the underworld. It was just a whim. He found it amusing that the top of an organization had become so broken and abandoned by their subordinates. That was all. At least, back then.
