Sanctuary (Karma Akabane x OC)

Disruption in the Classroom

Nagisa stopped walking, his eyes locked with someone who stood on the hill before him.

Katsuna, curious to see what has sparked his interest, followed his line of sight and let her eyes gazed upon a boy with crimson hair and pale mercury eyes.

"Nagisa, it's been a while."

His eyes travelled to the side, meeting Katsuna's heavy gaze. Holding the eye contact, he waited for the girl to glance away but instead she stood, unfaltering. The boy bit down hard on the straw of his strawberry milk before appearing uninterested, focusing his attention on the teacher in the distance.

"Oh hey!"

He scampered down the steps, all excited like a child in an amusement park, passing the two students without batting an eye.

"That must be the notorious Koro-sensei!" he marvelled, wandering up to the teacher in astonishment, "Wow! He really does look like an octopus, haha whatcha know?"

"Ahhh Mr Akabane I presume," Koro-sensei beamed, "I'm right in thinking your suspension ended today, welcome back!"

"Haha thanks for the warm welcome Sensei," Karma chuckled extending a hand to the teacher in front of him, "I've heard some great things about you teach! It's nice to meet you finally in person."

"The pleasure is all mine," Koro-sensei grinned, extending his tentacle towards the boy in return, "It'll definitely be a year to reme-."

As soon as his tentacle met Karma's firm grip, it exploded, the yellow gunk splattered onto the grass below. Koro-sensei barely had any time to react, taken back up the unexpected damage. Karma took this chance to throw his carton aside, revealing a anti-sensei knife stuffed inside his cardigan sleeve. His eyes narrowed, launching his arm towards his target at full speed, the knife slicing through the air dangerously close to Koro-sensei. Just in time, the teacher sprang into action, using his speed to jump back to a safe distance from student in front of him.

"Ho~ ho~, you are fast aren't ya!" Karma explained, recovering his balance to face his target, "And who would have thought these knives actually worked?"

"I just cut one up and stuck the pieces to my hand," he revealed nonchalantly, turning his palm to his teacher, "Pretty elementary stuff, I'm disappointed that's all it took to catch you off guard."

"But good jump," he continued, snickering, "if you wanted to come off as a coward. "

Karma tucked his hands back into his pockets, swaggering closer to his prey, "What?"

"You scared of me? "

The class stood in shock, all anticipating his next moves.

"I heard they call you Koro-sensei because you're supposed to be unkillable," he continued as Koro-sensei regenerated his lost tentacle.

"Oh come on.." Karma smirked, leaning in close to Koro-sensei, "No way you can be this big of a pushover."

Karma scoffed as he saw that his provocation worked. Koro-sensei's face had turned a vibrant red, his veins bulging out as he gnashed his teeth together.

"Hey Nagisa," Kaede inquired, "What kind of person is this guy?"

"Ahh..." Nagisa hesitated, not once taking his eyes of the situation, "He and I were in the same class back in our first and second year,"

"He was violent," he continued, "So violent that they finally suspended him and sent him here because they didn't know what else to do with him."

"I guess, under the circumstances," Rio commented, "He's probably the best suited student for this assassination task, considering his personality like you said."
