Intro
In modern Japan, there exists an incredibly crazy high school. Its name is...
《Kaosu Academy》
The worst and strongest high school, feared in other prefectures. Crazy classmates and crazy teachers. Even among them, the eccentric students known as the "Leaders of Kaosu Academy" were heading to school today as usual.
Sakaki, who was forced into the role of PE teacher despite it not being his job, stood in front of the school gate for disciplinary duty. He scanned the area with dark circles under his eyes.
The first to arrive.
Morning, Mr. Sakaki.
He flashed a smile, revealing his jagged teeth.
The second to arrive, touching his bandages.
Hmph, good morning, my people. My Pitch-Black Tracker shall become your shadow and support you...!
Full-blown chuunibyou from the morning.
.........Good morning.
He corrected himself.
Third.
Good morning... My sister was sleeping, so I left her behind.
A voice tinged with resignation.
