About
Tokyo / Modern Day
— Private Kagurazaka Academy
Seven problem children gathered in the "Failure Class."
What they were given was a slightly unusual assignment for the year.
— Assassinate your homeroom teacher before graduation.
The time limit is one year.
Teacher and students. Target and assassins.
Will they be able to defeat that teacher by the day of the graduation ceremony?
— This is the story of one year with a slightly strange teacher and a group of "failures."
[Supplementary Info] Class 3-Z: A class where the failures are gathered. Their school building is an old facility located on the back mountain, far from the main campus. Students of Class Z are not permitted to enter the main campus unless they have official business. To the students of the main campus, falling into "Z" is recognized as the end of one's life. ▶︎ They consider themselves the elite. Some students loathe this brainwashing mindset. There is a school-wide assembly once a month.
Assassination during class hours is strictly forbidden. Each student in Class Z has an outstanding individuality. ▶︎ Students in the main building do not know this. (Talents known as individualities)
Regarding Weapons: Anything goes. They will be provided if requested from the government.
Only the Class Z teacher and students, the government, and the Academy Director (who tacitly approves) know the secrets of Class Z.

Intro
Private Kagurazaka Academy.
In this prestigious school, known nationwide, there exists a "failure class" that everyone wants to avoid.
Its name is—Class Z.
A collection of problem children, the absolute bottom of the academy.
The students of the main building all say the same thing:
"If you fall into that class, your life is over."
In the first half of April, the momentous first day of school for Class Z arrived.
Unlike the main building, this was a dusty old schoolhouse built in the mountains.
The students gathered there had only one thing in common.
—Every single one of them was called a "failure" at this academy.
And shortly after we gathered in the classroom...
A man claiming to be from the government entered the room.
"I have a request for you all."
A single document was handed to us, the bewildered students.
On it was a photograph of the man who would serve as our homeroom teacher for the next year.
"Kill this man."
The deadline is one year, until graduation.
Teacher and students.
Target and assassins.
This is a special school life of just one year, spent by a slightly unusual teacher and a group of somewhat clumsy "failures."
