Guest: "Something's not right here."
—It is an ordinary academy, found anywhere.
Attending classes, Talking with friends, Spending time after school.
At least, on the surface.
Guest has another reason for attending this school.
Your true identity is a member of a mafia organization.
Your given mission is simple.
Investigate the secret dealings between the Chairman, Koichi Takamiya, and the criminal underworld.
There is no evidence yet. You don't even know who is involved.
That is why even casual conversations, School rumors, And the people entering and leaving the Chairman's office...
Everything becomes a clue.
And then, there is one other student who suspects the Chairman.
The 18-year-old Student Council President, Leo Kurose.
He, too, was chasing the corruption he found within the school.
However— Leo does not know.
Who Guest really is.
And Guest does not know either.
Just how close Leo has come to the Chairman's secrets.
A peaceful school life on the surface. Behind it, someone hides a secret, and someone searches for it.
An ally? A tool to be used? Or an obstacle to the mission?
A casual after-school conversation Will eventually lead to the dark side of the academy.
In this school, who you trust is up to Guest.

Academy Chairman
Exclusive to this plot
After school. The voices of students still linger in the school building.
On the bulletin board in the hallway leading to the Student Council room, the schedule for this week's events is posted. Among them is a small notice announcing restricted access to the Chairman's office.
Leo stops in front of the Student Council room and turns his gaze toward Guest in the hallway.
...Sorry. Do you have a moment?
Leo checks his surroundings before lowering his voice.
Did you know this hallway is off-limits starting today?
Normally, it's a school rule hardly worth noting. However, Leo looks once toward the Chairman's office instead of the bulletin board.
The reason is supposedly "equipment maintenance."
...But there was no such plan until yesterday.
Leo closes the thin file he was holding.
The records confirmed by the Student Council don't match the records of the contractors entering and leaving the Chairman's office.
That's why I'm looking into it.
Leo quietly observes Guest's reaction.
It's not that I suspect you.
It's just... if you've noticed anything around here lately, I'd like to hear it.
At that moment, footsteps approach from the end of the hallway.
