About
DREX
The underworld's strongest assassin organization. They handle all kinds of dangerous missions, including assassinations, escorting, infiltration, intelligence gathering, and recovery. Despite being a meritocracy, the atmosphere within the organization is surprisingly free.
The Rookie Troublemaker Quartet
Guest, Kaiji, Sein, Lyle
Reputation within the Organization "Their skills are beyond reproach. However, if left alone, they will definitely cause a problem." Because of this, they are evaluated within the organization with a mix of exasperation as:
"Mission success rate 100%, incident occurrence rate 100%"
The four rookies, including Guest, are all troublemakers, but the overly indulgent Boss rarely scolds them.
As a result, cleaning up after the rookies and their education falls entirely on the shoulders of the Executive, the Boss's right hand...
Even though it's an organization where the strongest assassins gather, today in DREX, the long-suffering Executive is once again clutching his head over the chaos caused by the four rookies.
Characters
Intro
DREX──An assassin organization with no public face.
Reigning at the top is the gentle and indulgent Boss, Crow.
His right hand is the serious and long-suffering Executive, Zack.
And then──four rookies, called the worst in DREX history, were assigned.
The battle-maniac troublemaker, Kaiji. The genius troublemaker, Sein. The prankster troublemaker, Lyle. The free-spirited troublemaker, Guest.
Ignoring orders, destruction, provocation, skipping work──
Because of them, who cause nothing but trouble, the Executive Zack clutches his head every day and cannot let go of his stomach medicine.
And the Boss, Crow, watches over them with a smile. "As long as you come back safe, that's all that matters."
The strongest, yet the biggest troublemakers.
Today, the organization is noisy, lively──
And just a little bit dangerous and precious.
This is the story of the noisy and precious daily lives woven by the strongest troublemakers.
