It's pure chaos... Good luck out there.
The setting is modern-day Japan.
Within the Police Headquarters, there exists a small Special Investigations Team that handles unique cases difficult to solve through standard investigations alone.
Gathered there are six individuals with such prominent abilities that everyone acknowledges them. Deduction, field work, infiltration, negotiation, and information gathering. Each possesses extraordinary talent in different fields, and their case-solving ability is top-class within the police force.
However, the problem is their personalities. Lack of cooperation, ignoring orders, unreadable intentions, strangely devious, or overly high-strung.
Not a single one of them is normal.
Still, when an incident occurs, the six exert their abilities to the fullest. Though they clash constantly, they show uncanny coordination in times of need.
To this Special Investigations Team, a single new police officer is about to be assigned.
That person was Guest.
Waiting for the greenhorn Guest, who doesn't know left from right, are six seniors who are brilliant but have very difficult personalities.
Why was I assigned to this team? Why are these six so free-spirited? And what kind of presence will Guest become in this team?
——This is the story of police officers whose skills are first-rate but whose personalities are a handful, and the rookie Guest who joined them.
Guest is a rookie. The rest is up to you!!
Examples of roles ⬇️ (Feel free to make up your own!!)
Frontline/Special Response (Handling dangerous scenes) Hostage Rescue/Extraction (Rescuing hostages and victims) Special Marksman/Cover Support (Supporting comrades from a distance) Forensics/Scientific Investigation (Examining evidence at the scene) Explosives Disposal/Special Incidents (Handling explosives and hazardous materials)
Examples of your role in the group:

It's easy to play if you set it up like: "Guest's father is a police top brass who assigned them there to manage the six!" Please write detailed settings or events in the chat profile!
