Third person point of view

"You're talking to a transfer student who has only spent five days in this school. How do you expect her to know anything?" While Mika would rather not get involved, she couldn't stand such nobody to talk to her friend that way. "Unlike those dorks in the campus ranked below us, we don't exactly find joy in merely ridiculing you folk. I'd say your existence isn't even worth the discussion."

["Please calm down, Morikawa-san.."] Ginka could feel her tension rising despite the calm demeanor. It was getting dangerous.. 

Class B values getting along with others and the very least considered one of the "good apples" in the main building, most of them. They don't enjoy picking on the weak but rather promote healthy rivalry, directing them more at Class A known to overshadow them. 

"Yeah right, and this so-called transfer student also happens to be the daughter of that monster board chairman of this very school. Let's be real, she should be knowing a lot more than the students themselves." At this point, Karma is just amused with all these excuses. This is literally their family business. She is even a candidate for succession. She should be trained by now on how to take over so this whole thing of her being ignorant is a total joke. 

But Ginka was never considered as such and truly knew nothing. Perhaps there is fault in that. She got herself in a school without fully grasping how it works and just says whatever she pleases, as per the redhead thinks.  While she is aware that there are five classes in total, she had no knowledge that one of them is secluded in the mountain with how big their school actually is. 

"Anyway, just don't classify us the same if we don't get treated the same. We don't suck up to silly lip service." He taps her shoulder before waving as he leaves, "Better just leave us alone. You will lose all your allies if you keep associating with us, Asano-san~"

Of course, Ginka couldn't simply ask what he meant by that since her obliviousness might come off rude. She just ends up watching the bluenette calling his name as he catches up to him, tapping their cards to enter the Kunugigaoka station. 

["Morikawa-san, what is it that I do not know?"]

Unlike her brother, Ginka has not once stepped into the business world. Questions about her family don't get questioned as she had always presented herself under the stage name of "Seiun" until now. Therefore, the way that Gakuho truly controlled the school never reached her ears. It also didn't help that she was away from them almost half her life. 

"You know what they say, ignorance is a bliss. It's best to just take his advice and leave them be." Mika shrugs. 

["But my words have hurt them in some way and while I do want to apologize for it, that would be meaningless if I had no idea about the origin of my mistake."] 

"Look, you did nothing wrong. If anything, Akabane-kun was out of line speaking as if he knew everything about you." 

["Putting it that way.. Am I also not the same?"] Ginka smiles weakly, attempting to convince her friend once more. ["It's no use keeping me in the dark. I'm pretty sure I could get this information by asking around. Why not just come clean with it?"]

Mika wouldn't hear the end of it if she didn't give in now especially when they'll still be together waiting for the train. Taking a deep sigh, she continues walking with her following from the side. "Alright then, listen carefully." 

On the other end, Nagisa was more bothered that their defense came off rude towards a transfer student who hasn't been to an actual school for years and still adjusting to the environment.

"Weren't you kind of aggressive with the way you handled Asano-san just now?" 

"Am I wrong though?" But maybe he did go a little to far with his taunting over there, "How is it that you don't see it? She's dangerous, Nagisa-kun."

Nagisa didn't understand where he was coming from, "How exactly..?"

"Her overall vibe, doesn't she catch you off guard?" She didn't even do anything but stand there and people would still be drawn to her. 

"Well, she does have the air of a celebrity. Pretty eyes too." Nagisa pretty much froze for a moment upon meeting her gaze. She had that strong presence hard to ignore. "But what does that got to do with anything?" 

"Maybe I just want to deny her." That Ginka couldn't be genuine. That he now knows she lives by two identities, and maybe not one of them is even real. 

If she's just naturally good at enticing others whether she drops the mask or not, how do you tell the truth from a lie? An ally or foe? She could look innocent and harmless but still hide blades under the surface. A talent that he could never have unless born with it. There's a threat to that. 

It's almost the same danger he felt in face with Nagisa's. 

And said person still couldn't figure what Karma was talking about since the he wouldn't go into detail. It wouldn't be right to pry either. He was unsure if they were close enough to go deeper into that in the first place, "Can you at least try not to provoke her?"

Well, Karma can't really promise anything since he's more on doing what feels right at the moment. So he just switches topics to ask the main issue at hand: their teacher's weakness, which Nagisa willingly gave the information of. 

"I see. I've thought of something nasty." He almost choked up a laugh. 

Which his friend couldn't help but be concerned. "Karma-kun, what are you planning to do now?" 

"You know, I'm really happy. I was wondering what I would do if he were just a monster but," He gave off a disturbing smile that sent goosebumps down one's spine. "I'll be able to kill a proper teacher, since the previous one died out of his own accord."

He felt the grudge of being unable to do it himself, projecting such ill feelings on his kind instead. 

They are all liars. 

"Ah, soorry! I mistook it for you and end up killing it. I'll throw it away, so just bring it over here." Karma spoke with full arrogance, pointing at the octopus he stabbed on the desk. As he is unable to kill him as of the moment, he attempts to kill his spirit bit by bit.

Only for Korosensei to finally counter his antics, backing him into a corner. 

"Sensei never lets an assassin be bored." His eyes lit up in determination, cooking up takoyaki with a missile and tentacle drills along with several ingredients he fetched in mach speed. The redhead chokes as the finish product shoved into his mouth, "That complexion comes from not having eaten breakfast, doesn't it? I have made much more. If you eat this, you'll come closer to be a healthy child."

Karma raises his sleeve to cover his mouth. He is an octopus who has little to no limitations. Unpredictable more than anything.

"You should come at me each day with a serious intent to kill. And each time, I will improve you." He continues, throwing back the same level of mockery his student did. "Before school lets out, I will polish your body and spirit until they shine." 

2nd period. 3rd period. 4th period. 5th period. The entire day has passed and none of Karma's series of attacks had any success whatsoever. He just made a fool out of himself playing into his teacher's hands.  

It was his loss. All his ideas had dried up.

But still pondering about it more until the day ended, biting his nails in frustration. "Karma-kun, don't be impatient and we'll kill him together. If you target Korosensei by yourself, no matter what tricks you use, you alone can't kill him. He's different from other teachers, after all."

Teacher. Teacher. Teacher. The more it echoed in his head, his bloodlust intensified that he no longer submits to reason. He leers forward, "No way.. I want to kill him. Surviving by some fluke will piss me off the most."

And the said target appears before them, "Now, Karma-kun. Today, sensei certainly provided you with lots of improvements." The stripes on his face indicated provocation, "You can still kill me, you know? I will polish you until you shine even brighter."

Suddenly, he had another plan in mind. The final one, probably. It was a plan that would work for him whether or not he succeeds.. no matter how insane it may seem. 

"I'd just like to confirm but you're a teacher right, Korosensei?"

He was confused on why he was asking the obvious, "Yes."

"So would a teacher put his life on the line to protect his students?" He stands up from swinging his legs from being seated on the tree hanging off the cliff. 

"Of course. A teacher's a teacher, after all." 

"I see, that's good." Karma gives off a smile like he's finally lost it, "In that case.." 

He points a gun at him and takes a step off the branch, allowing himself to fall to his death. 

"This time, I'll definitely kill you."
