fraternizing with the enemy (assassination classroom fanfiction)

Introduction to assassination time (edited)

(Just so I can work my timelines correctly, canonically Takaoka appeared after the Kyoto trip. Which as it isn't mentioned I am going to say both of these events happened in late April early may. Also because of being in the hospital Ayame and Karma do not meet Takaoka, nor are they present for the first introduction of Itona or Ritsu.)

After being spotted by Karma, Koro-sensei had no choice but to retreat. With a flair of yellow movement, he dissolved into his liquid form and slithered through the air ducts, carefully positioning himself within the hospital's ventilation system. He could still hear the faint hum of his wireless mic as it was disposed of, lost to the ground outside with all of his hard-earned money and purchases along with it. Koro-sensei threw a small tantrum in his hidden corner, grumbling about the loss, but there was little time for self-pity.

Settling in for the night, he remained in his liquid form, listening in from above, his tentacles twitching in response to every movement and whisper below. Though he didn't learn much more than the fact that Ren's parents had agreed to send him to a psychiatrist to help with his recurring nightmares (and that he would be absent the next day), Koro-sensei took solace in knowing one thing: if the students were ever attacked again, he would be there to protect them. And that was enough for now.

The Next Day, 5:00 AM

Koro-sensei had stayed awake all night, moving from the hospital to the school to gather the last bits of information. Though fatigue gnawed at him, he pushed it aside, focusing on what needed to be done. It was early, far too early for anyone, and yet here he was, preparing for the chaos that would undoubtedly unfold later that afternoon.

As he arrived at the school, he was surprised to find both Irina and Karasuma waiting for him outside, though Irina looked as if she had only just dragged herself out of bed. Karasuma, ever the professional, glanced over at the yellow teacher, feeling the rush of wind that accompanied his arrival.

"You were right, Octopus," Karasuma said, his tone flat but steady. "The principal sent the papers for both Asano Gakushū and Sakakibara Ren's transfer to E-Class at midnight."

A slight frown pulled at the corners of Karasuma's mouth, but it was clear he was trying to hide his discomfort. Koro-sensei's response was measured. "I see."

Irina, her patience wearing thin, crossed her arms and tapped her foot impatiently. "Well, I don't know about the two of you, but it's five-thirty in the morning, I'm exhausted, and it's freezing! The sun isn't even up yet, so if you want to talk, do it inside!" Without waiting for an answer, she turned on her heel and stormed toward the building.

Koro-sensei and Karasuma exchanged a brief, knowing glance before following her inside, the cold air biting at their skin. Once the three of them were settled comfortably in the office, they began discussing the plans for the day.

"Irina, are you still okay to cover the P.E. lesson later while Karasuma and I go see Sakakibara-kun and Asano-kun?" Koro-sensei asked, his voice tinged with a bit of concern.

Irina rolled her eyes but gave a resigned nod. "I already said yes. Not gonna change my mind now."

"Well, with that settled," Koro-sensei continued, "the octopus and I will leave as soon as his lesson is over—"

But before he could finish, the ringtone of Karasuma's phone blared through the otherwise quiet room. Karasuma sighed as he picked up the call, the frown on his face deepening as he listened.

"Hello? Yes, sir... today? I understand... of course... Goodbye." He hung up with a weary sigh.

A slight pause stretched between them before Karasuma spoke again, his voice low. "Slight change of plans. We may have to wait until after the school day to go to the hospital. That was my boss—they want Takaoka to cover the P.E. lessons. Apparently, I have too much work. I'll need to stay behind and do some background checks before he starts, so that'll have to be prioritized."
