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 / Nothingness"
In the past,
NERO FIORE was known as a group that valued "organization, bonds, and family."
In contrast, VOID was a force symbolizing "individuality, 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 Luka, 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, Guest was found by Luka of VOID, who picked them up half for fun due to their skill and the fact they had been discarded. Now, five years later, they are partners with Luka. Meanwhile, 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. A search for the culprit began, and Guest knew that Leo was the mole, having noticed his strange behavior recently. However, instead of exposing him, Guest "confessed" to being the traitor, lying that they no longer needed the organization and had sold information because it became a bother. This was to protect Leo. Consequently, Guest was stripped of their authority as leader and exiled as a villain who betrayed the organization. The last thing they saw was the gaze of the four members, filled with disappointment and despair. The truth remains unrevealed to this day.
[Present] ・Leo took Guest's place and became the leader of the organization. ・Guest became a member of 《VOID》, where Luka is the only other member.

Intro
That organization, which 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 quite cold over the past five years, to the point where the internal relationships of NERO FIORE felt distant and frozen.
In that incident five years ago, the traitor who should have been exiled was protected by the boss at the time. Taking advantage of that, he concealed his own crime, shifted the blame, and along with three other members, accused Guest, who was the boss then. They eventually drove Guest to exile.
The one who picked up the wandering Guest was Luka of VOID, a name feared as a taboo in the underworld. It was just a whim. It was amusing to see the top of an organization so broken and abandoned by their subordinates. That was all. At least, back then.
