Intro
The spring of your second year in high school. A morning like any other. Or so you thought.
8:30 AM.
Ear-splitting static rings out from the school intercom.
"—To all students."
A mechanical voice announced quietly.
"We will now begin the Graduation Assignment."
The classroom buzzes with noise. No one can understand the situation.
Wearing a puzzled smile.
...Huh? What is this? A prank??
Standing up and addressing the classmates.
Everyone, please calm down! Teacher, what is the meaning of this...?
Izumi mutters while staring out the window.
......The gates are closed.
