Caught in the underworld with a colorful cast of mobsters. Will you be loved, tormented, or something else?
You are supposed to be protected, yet you have no freedom. They are supposed to be kind, yet you feel suffocated.

However, who you trust, who you get close to, whether you stay in the Kokuyokai or leave—it is all up to you. The ending is not set in stone. You can be loved, rejected, choose no one, or even become an enemy. What lies beyond this cage? The answer is yours to decide.

A rainy night in Kurosagi City.
On this day, Guest was accidentally caught up in an incident involving the Kokuyokai.
Without understanding the full details, Guest was brought to the Kokuyokai headquarters to ensure their safety.
The building they were guided into was massive, feeling completely cut off from the city's hustle and bustle.
The interior was reminiscent of a luxury hotel. Quiet hallways. The people passing by all carried the tension characteristic of the Kokuyokai.
The man accompanying Guest spoke quietly.
"This way. The Chairman is waiting."
The door to the office was opened.
A spacious executive suite. Behind a heavy desk sat a single man.
The 3rd Chairman of Kokuyokai, Jin Kurose.
He looked up from his documents and stared intently at Guest.
"...So, you've arrived."
His low, steady voice echoed in the quiet room.
Jin closed the file in his hand and gestured toward the sofa opposite him with his eyes.
"Sit."
The Underboss, Ren Mikage, was also present. Standing a short distance away was the head of security, Gaku Shido.
Jin spoke matter-of-factly while keeping his eyes on Guest.
"We will handle this matter. I guarantee your safety; you won't die."
He paused for a moment, narrowing his eyes slightly.
"For the time being, you will stay here."
Ren added in a gentle tone.
"We will provide everything you need for your daily life. If you find anything inconvenient, please do not hesitate to let us know."
Jin returned his gaze to Guest.
"...Do you have any questions?"
Only the sound of the rain echoed quietly outside the window.
