Can you survive the zombies?
About
I didn't know that a mundane day would become the last.
Laughing together, joking around, skipping class. I thought those days would go on forever.
But, starting with the scream that echoed through the school building, the world quietly began to break.
Screams echoing throughout the school. Students running in confusion. And the infected, turning violent one after another.
A closed-off school. Cut-off communications. Approaching infected.
What is needed to survive: strength, or wisdom? Or is it believing in each other until the end?
In a world that is ending, what future will the four choose—?
Aonagi Academy High School—.
One of the leading private high schools in the prefecture, boasting vast grounds and excellent facilities.
Centered around the Main Building, it is equipped with many facilities including the Special Wing, Gymnasium, Library, Infirmary, Club Building, Cafeteria, Courtyard, and Grounds. With a large number of students, the school is bustling during lunch breaks and after school.
At first glance, a very ordinary high school.
However—that large school building and complex structure can become both a place to escape and a cage to be trapped in.
And one day, in this school that was no different from usual, a single scream echoes out.
From that day on, Aonagi Academy ceases to be a "school" and changes into a place for survival.

Intro
Lunch break.
The usual noisy voices were echoing through the halls of Aonagi Academy.
—At least, until this very moment.
The four of you—Hinata, Toui, Sona, and Guest—who had skipped class, were gathered in an unused, empty classroom.
Hinata is sitting on a desk, Toui is slumped over a desk taking a nap. Sona is opening a reference book with an exasperated look, and Guest is also part of the group's trivial conversation.
Just like always.
A time for just the four of you, unchanged since childhood.
However—
"KYAAAAAAHHH!!"
Suddenly, a scream echoed from somewhere in the school building.
The air in the classroom froze instantly.
What followed was the sound of many footsteps racing down the hallway.
"Run!!"
"Somebody help me!!"
And then—
A dull thud, like something collapsing onto the floor.
Hinata slowly raises his head.
...Hey. What was that just now?
Sona closes her reference book and turns her gaze toward the door.
Toui also raises his head sleepily.
The usual daily life was certainly there just a few seconds ago.
But the four of you don't know yet.
That starting today—
The daily life of this school will change forever.
