Heyo! Back with more fanfiction trash!

Third Person view

The classroom was filled with chatters and whispers.

Karasuma-sensei was in front of the class, along with a blonde woman who was clinging affectionately to Koro-sensei.

After a moment, Karasuma-sensei spoke, "...Allow me to introduce the part-time foreign language teacher who has come today."

"My name is Irina Jelavic. Nice to meet you all!!" The woman said with a cutesy voice, still clinging to Koro-sensei.

Karasuma-sensei sighed, "The school's intention is to fully immerse the students in a foreign language.

He glared at the alien, "I assume there are no problems with her taking charge of half the English class?"

"It can't be helped, then."

Kaede spoke to Nagisa, "...A pretty amazing Sensei turned up. She seems nice to Koro-sensei."

Nagisa sweat dropped."Yeah..."

But Nagisa thought it was a good thing. That Irina woman was probably a pro assassin right? Why else would they send her here?

Karma, on the other hand, just sits in his chair, looking in front uninterestedly.

He couldn't care less if there was a new teacher or not.

He took a glance at Nagisa, who was scribbling in her notebook. Wait, why did he glance at her, again?

-Time skip-

The class was outside, playing soccer and training at the same time. Well, you know, until Irina-sensei butts in.

"Koro-sensei~ I heard from Karasuma that you're suuper fast! Is that true?"

The yellow alien blushed, "Well, not that fast..."

"I have a favor to ask! You see, I've been wanting to drink genuine Vietnamese coffee... Would you buy one for me?"

"Well, I do know a really good coffee shop in Vietnam."

Aand... he was off.

After a moment of silence, Isogai spoke up. "So, um... Irina-sensei, class is starting soon, should we return to class?"

Irina-sensei's face that was full of affection and love quickly turned to disgust and annoyance. She lit up a cigarette, "Class? Oh, right. You are all free to do what you want."

Everyone's faces were now shocked and confused. They know that the cutesy Irina-sensei was just an act, but they didn't expect the real her to be... this.

"Also, can you stop being so familiar with me by calling my first name? Call me 'Jelavic-oneesama'."

"..."
The class was quiet.

"So, what now, Bitch-neesan? "
Karma walked forward.

"Don't shorten it!!" said Irina-sensei, no, I'm sorry, I mean Jelavic-sensei.

"Can you really kill that yellow monster, when the combined efforts of the whole class can't?"

She smirked. "There is a difference on how brats and adults do things."

She turned her head towards Nagisa.

"You. You're Shiota Nagisa, right?"

Without giving her a chance to answer, she pressed her lips against hers.

Everyone is shocked. Kaede has her mouth wide opened. "W-WHA-"

Karma was also shocked, and he felt something weird inside his chest...

10 HIT!

20 HIT!

30 HIT!

Nagisa gradually loses her strength, and is now embraced by the blonde.

"Come to the faculty room after this. I want to hear the information you got on that guy."

She released her embrace from Nagisa, and the blue haired girl instantly fell.

"Though I have plenty of other ways to make you talk."

"H-hold up! I-I don't even swing that way!! " Nagisa thought, still on the ground.

"As for the rest of you! Those who have useful information, come speak to me! I'm doing you all a favor. And I'll even lend some manpower to the girls."

3 armed men came, one of them giving her a gun.

"And if you get in my way of assassination... I'll kill you."

And she walked away.

Class E realized that their new so- called 'teacher' is rather- no, really detestable.

After she walked away, Karma grabbed Nagisa and started wiping her lips with his black jacket.

Nagisa struggled, but to no avail.
"K-Karma-kun! What are you doing!?"

The red head had an angered expression, and showed no sign of stopping. "Cleansing you, duh."

Kaede came up to her, running with a box of tissues."N-N-Nagisa... That was your... Your first kiss r-right?" Tears formed in her eyes.

"I-I feel so bad for you, Nagisa... *sniff*"

Nagisa thought for a moment. "Huh. I guess that was my first kiss."

She wanted to say that aloud, but Karma was still rubbing her lips.

"Waah!! Nagisa!!" The green haired girl said and ran up to hug her.

Seeing the situation she was in, she giggled. "This is actually pretty funny..."
