Chapter 3: Kuroko no basuke x assassination classroom

Karma laughed as he saw nagisa's face flush once he commented about the boy's feminine figure. He could also swear he saw kayano giggle beside him.

"karma-kun, don't laugh!" that only caused the redhead to laugh harder.

"mou, your so mean" whined the bluenette as he pouted. Kayano smiled.

"its fine, I think your figure is a part of your charm" commented the girl as she patted the other male on the shoulder. He returned her smile.

"thank's kayano-chan"

"but I am kinda jealous that you have such a nice waist" she stated with a thoughtful look.

"I mean" she glanced down at her chest, then at nagisa's. A depressing aura surrounded her "out chest is not much different so at least let me have the waist" she complained as her form slumped.

Karma placed his hands behind his head as he looked straight (yeah right) and stated bluntly "might as well, its not like that's gonna grow"

He had to dodge an incoming blow.

"karma!!" he laughed once again as he saw the fuming girl. Nagisa laughed awkwardly.

"now now, kayano-chan please calm down, karma-kun please stop" nagisa said as he led the girl away from the redhead.

"aw, but you two are so easy to rile up" karma complained with a pout.

"its not like your so perfect too, you know" said the bluenette.

"yeah, I mean, your far too overconfident" stated kayano with a glare. Karma puffed his chest.

"that's because I have the right to be" he stated confidently.

Nagisa rolled his eyes playfully "yeah right."

"nyuru fu fu fu, I see my favorite students are having fun" said koro-sensei appearing out of nowhere with his signature grin- er, face.

The three turned around "koro-sensei?" asked nagisa.

"what do you want, octopus?" karma said, taking out the green knife they used to injure their sensei and pointing it at him.

Koro-sensei flinched, very noticably might I add. The red head inched the knife forward even more, raising a brow.

The yellow octopus fidgeted.

"u-um, you see, I might need your h-help" he stuttered out. Confusion crossed the student's features.

What could an alien octopus that can move at mach-20 speed that blew up the moon need help with? and after class?

"what is it, koro-sensei?" asked nagisa pushing karma back.

The octopus deflated in embarrassment "nyuru, just follow me" he said. The three glanced at each other but complied nonetheless.

They arrived at the class 3-E building, or at least, what used to be the building.

"uh, koro-sensei?... what... what happened?"

The whole building looked like it was burning but that's just impossible since they could have sworn fire was red. Not rainbow. And fire was a gas right? not a... liquid? a vacuum perhaps? It was bright, almost blinding, swimming in a myriad of colors.

"what did you do, octopus?" asked karma looking at the building with a raised brow.

Koro-sensei panicked as he ran around "nothing, I swear! but this thing is impossible to stop and its quickly spreading!" cried the teacher.

"mhm" stated karma raising a brow.

"I swear!" the alien once again panicked.

Nagisa tried to reassure his teacher "alright, alright, it doesn't matter who's fault this is, what's important is that-" nagisa's eyes turned deathly cold "-we stop it"
