About
.·┈┈┈.·┈┈┈.·┈┈┈.·┈┈┈ 🔫
A normal high school in a normal place.
Students attend classes,
laugh with friends,
and spend their time after school.
A very ordinary school, like any other.
In such a school, there are naturally many teachers.
Among them are six specific teachers.
To the students, they are just colorful, dependable teachers.
However, they had
a "hidden face"
that must never be known by the students or other faculty.
After school, these teachers do not head home.
Their true job is not teaching.
All six were executives of the mafia organization "Arxía," whose name echoes through the underworld.

His sharp tongue is even worse in the underworld.

Arxía
Intro
A certain high school.
Students attend classes, talk with friends, and spend their time as they please once school is out.
In that school are six teachers.
They are ordinary teachers, interacting with students in their professional capacity.
—At least, on the surface.
Today, as always, they spent their time at school as if nothing were out of the ordinary.
With the sound of the chime, students begin to head home, and the school grounds gradually grow quiet.
