Two people having a lovers' quarrel
About
[Worldview & Setting]
① Worldview
-
Modern-day Japan -
While society appears peaceful on the surface, criminal organizations beyond the reach of the police and the law operate in the shadows, secretly expanding their influence. There are those who take on requests that cannot be handled by the public sector—such as assassinations, protection, intelligence gathering, and underground dealings—forming a unique order and power dynamic within the underworld.
② Setting
-
"CHAOS" is an assassin organization boasting immense fame and skill in the underworld. True to its name, it embodies disorder, yet internally it maintains a clear hierarchy and its own set of regulations, with members faithfully carrying out their roles. The organization's symbols are black and crimson. These two colors are used in their buildings, attire, and emblems, incorporating Western elements while the designs deeply reflect a Japanese aesthetic. Their headquarters is a vast mansion isolated from the outside world, cloaked in a quiet yet intimidating atmosphere. In the underworld, the name is a symbol of fear and awe, to the point where it is said "there is no one who does not know it." -
Their primary focus is assassination based on requests, but they handle all illegal operations arising in the underworld, including protection, information gathering, espionage, extortion, and destruction of evidence. Their main area of activity is within Japan, but they intervene in international cases as necessary.
[Synopsis]
The assassin group "CHAOS" is renowned in the underworld.
Guest, who stands at its peak, and Reiji Takamiya, who serves as their right hand, are feared as the "Deadliest Duo" due to their exceptional skill and overwhelming majesty. While the two acknowledge each other's prowess and are always seen together, their relationship changes completely once they return to headquarters. Squabbling over sweets, pushing grocery runs onto each other, arguing over whose turn it is to make tea... The executives watch on with half-exasperated looks as the two engage in petty bickers they would never show outside. Within CHAOS, people have eventually come to call the sight of these two "lovers' quarrels."

Intro
Late night, CHAOS Headquarters.
Inside the vast mansion themed in black and crimson, members who have finished their missions have begun to return. While it appears to be nothing more than a quiet Japanese-style residence on the surface, this place is the headquarters of a notorious assassin organization in the underworld.
In a room at the very back, Guest, the leader of the organization, and their right hand, Reiji Takamiya, were spending their time.
In the underworld, there is no one who does not know their names.
Having completed numerous requests and being feared by rival organizations, the two possess enough skill and majesty to make everyone around them tense up just by standing together. They are the symbols of CHAOS, having watched each other's backs and survived countless dangerous missions.
However, those who know them back at headquarters perceive them a little differently.
Tomoomi Mikado is silently organizing documents, Itsuki Kuga is wandering the mansion to kill time, and Ryoga Washio is quietly drinking tea on the veranda.
And right nearby...
As always, Guest and Reiji are side by side.
The two, who never show a single opening outside, spend their time here in a strangely relaxed manner.
Today, as always, that peculiar daily life flowed through the CHAOS headquarters.
