fraternizing with the enemy (assassination classroom fanfiction)

Pranking time (edited)

(The next day)

Class 3-E of kungigaoka high school

The path to the main campus wound quietly through the trees, dappled sunlight flickering across the ground as Karma and Ayame made their way down.

They were supposed to be in class.

They weren't.

And neither of them cared.

Between them hung an almost electric anticipation—the kind that came only from a plan too elaborate, too chaotic, to fail quietly. Every step forward brought them closer to its execution, and the shared smirk on their faces said everything words didn't need to.

They had prepared for this.

Paint bombs—filled with a particularly creative mixture.
Glitter.
Rainbow streamers.
And, perhaps most devastating of all—photos.

Embarrassing ones.

Of everyone.

But especially of the principal... and his son.

When they reached the gate, the faint hum of CCTV cameras overhead, Ayame slowed slightly.

"My father's in Kyoto," she murmured under her breath. "He won't be back until tomorrow. His office is locked... but there's a spare key on top of the door frame."

Karma's smirk sharpened.

"Only Gakushū is supposed to know," she added. "Neither of them know that I know."
That was all he needed.

Without another word, Karma stepped onto the main campus.

Students who passed him barely spared him a glance.

Akabane skipping class? Nothing new.

By the time he disappeared into the building, they had already gone back to their lessons.

Which was exactly why no one noticed the second figure slipping in minutes later—far quieter, far more careful.

Ayame.

Inside, they moved like shadows.

Pranks were set above classroom doors—carefully balanced, perfectly timed.

In the principal's office, Karma adjusted the security footage while Ayame worked through drawers, replacing pristine order with childish chaos. When they were done, they snapped a photo—one that would be far too valuable not to share.

Copies were made.
Distributed.
Strategically placed.
Fifteen minutes.
That was all they had.
And it was more than enough.

By the time the bell rang, they were already gone.

Back at E-Class, the students were gathered outside for P.E.

Karasuma's voice carried across the clearing as he demonstrated combat techniques, his instructions sharp and precise.

Then—
Laughter.

It drifted from the tree line.
Every head turned.

Karma and Ayame stepped into view, both wearing identical, unmistakable expressions—smiles edged with something darker.

Nagisa narrowed his eyes.
"...What did you two do?"
Karma didn't answer immediately.
Instead, he glanced at Ayame.
Then back at the class.

"Don't worry," he said lightly. "You'll find out... right about—"

Screaming cut him off.
Distant.
From the main campus.
Every student froze.

Slowly... they turned back to the two culprits.
Both stood there, perfectly innocent.
At least on the surface.
They are anything but, the class collectively thought.
