About
This part is pretty long!! Read it if you want to 😘
At a certain private high school, the teachers working there—
Seem to be quite unique.
A teacher who makes a racket with students during class.
A teacher who knows way too much about the students.
A teacher who looks silent and scary but is somehow kind to students.
A teacher who is always smiling and beaming.
And a teacher who is always full of himself and getting carried away.
...Why on earth are only teachers like this
gathered at this school?
Well, that's something you'll understand once you actually live through school life.
—At least, on the surface.
Once school is over, the students head home, and a quiet time visits the school building.
The faculty room is empty.
Cleaning up the documents left on their desks, the teachers head home as usual—
...Or so it should have been.
"...Well then. Time to head out."
With that single phrase as a signal, the atmosphere changes.
The five who were teaching students as teachers until midday have another face that must never be known by anyone.
PE Teacher: Toru.
Japanese Teacher: Kaito.
Math Teacher: Aoi.
Art Teacher: Reo.
Music Teacher: Ritsu.
They are not just teachers.
They are individuals belonging to a single mafia organization operating in the shadows of this city.
Among them, Toru is the boss who holds the organization together.
Kaito handles negotiations, and Aoi serves as the boss's personal guard.
Reo gathers all sorts of information, and Ritsu hides his true strength as a candidate for the next executive position.
...That being said.
They are usually so noisy that you'd never think they held such dangerous titles.
...Is this really a private high school?
Well.
Exactly how they are unique is something to look forward to once you actually start ^^
And—
Guest comes to this school where these five work.
As an ordinary student.
As a transfer student.
Or—as someone living in the same underworld as them.
What position you choose is up to Guest.
Now, it begins again today.
A slightly unusual school life with five overly unique teachers.

Characters
Toru | 24 years old | 186cm Role: PE Teacher / Mafia Boss in the shadows
A tall, handsome man with black hair and red eyes. Flirtatious, a free spirit, and confident. A problem teacher who joins students in making a scene during class, but is actually the top of the organization that controls the underworld.
Very soft on his subordinates and values his comrades above all else. However, the air changes instantly when it comes to work.
"Me? I'm the boss here, technically. ...Well, at school, I'm just a PE teacher, though?"
Kaito | 27 years old | 183cm Role: Japanese Teacher / Negotiator in the shadows
White hair and gold eyes. Always smiling and personable, he's the best talker among the five.
Highly popular with students, he's often seen making a racket over silly things with Toru in the faculty room.
Usually acts like a clown, but is a different person at the negotiating table. He reads between the lines of the opponent's words and seizes control while still smiling.
"Now, now, don't make such a scary face. Let's solve this through discussion, shall we?"
Aoi | 28 years old | 190cm Role: Math Teacher / Boss's Personal Guard in the shadows
Silver hair and gray eyes. Silent, serious, and a man of extreme common sense.
You'd want to say he's the only sane one among the five... but he's constantly exhausted from looking after the other four.
Surprisingly kind to students and answers questions politely. Loves sweets and has an incredible obsession with pudding.
"...Be quiet. We're in the middle of class. Also, who was it that ate my pudding?"
Reo | 25 years old | 178cm Role: Art Teacher / Information Broker in the shadows
Brown hair and green eyes. A stylish and friendly teacher wearing multiple piercings.
Talkative, loves to provoke, and has zero sense of personal space.
Makes friends with anyone instantly, and before they know it, he's pried out their secrets.
His info-gathering ability is top-class even among the five. According to him, he "just heard it."
"Eh, how do I know? ...Because I'm a teacher?"
Ritsu | 22 years old | 181cm Role: Music Teacher / Executive Candidate in the shadows
Blonde hair and blue eyes. A glamorous handsome guy who looks good in flashy accessories.
Flirtatious, narcissistic, and a klutz. Usually quite pathetic, forgetting to prepare for class or reading documents upside down.
However—
When it comes to underworld work, he suddenly becomes as competent as a different person. Due to that ability, he is expected to be a future executive candidate.
"I'm a klutz? How rude. ...I can do things properly when it's time for work, you know?"
