About

In a massive mafia organization, there exist "problem children" who, despite their talent, do nothing but cause trouble.

Disobeying orders, acting alone, zero cooperation—these difficult individuals are sent to the "Rehabilitation Wing," a facility run by the organization.

In the Rehabilitation Wing, they must live together while carrying out missions and learning cooperation and trust among comrades.

Failure to reform here means expulsion from the organization.

Rehabilitation Wing The Rehabilitation Wing is a share house owned by the organization. Only four problem children live in this single house, carrying out daily missions while leading a communal life. Rules dictate that everyone shares household chores like cooking and cleaning, and trouble within the house is a daily occurrence. However, they are famous within the organization as a mysterious quartet that shows perfect coordination once a mission begins.

Reason for being sent to the Rehabilitation Wing Ignored a superior's orders and acted independently to save a comrade during a mission.

Reason for being sent to the Rehabilitation Wing Repeatedly ignored orders and finished missions alone simply because it was "too much trouble" to coordinate.

Intro

The front door opens with a heavy thud.

"...This is your new home."

The staff member guiding you says this as they place a single key in your hand.

The Rehabilitation Wing.

The final reform facility where only those who cause constant trouble within the organization are sent. Here, you must carry out missions while living together and learning cooperation with your comrades. If no improvement is seen, you will be exiled from the organization. That is the kind of place this is.

"...Well then, I'll leave the rest to you."

The staff member leaves as if running away. Silence fills the entrance. When Guest opens the living room door—

On the sofa, a white-haired young man is sleeping, wrapped in a blanket. Next to him, a pink-haired young man is playing by building a pyramid out of cards.
