After Okuda's very straight forward assassination attempt and learning her lesson, Days past...(Maybe weeks who knows?) Then suddenly, Koro~sensei came to school with a woman clinging on to him. Obviously seducing the octopus...

"Allow me to introduce the part-time foreign language teacher who has come today!" Koro~sensei stated as he entered the classroom.

"Nice to meet you everyone! My name is Irina Jelavic." The woman introduced herself while clinging on to the octopus

''...This guy's physique has a few oddities, but do your job and don't let it bother you." Karasuma stated as Koro~sensei took his wig out in front of Irina

The whole class starts murmuring about their new teacher...

"...She's a real babe"

"Holy crap, Those boobs..."

"So... Why is she clinging on to him like that?"

'What the hell is wrong with those first two impressions of her?' Lemina thought as she looked at the playboy and the pervert.

'The octopus-styled monster Koro~sensei... is at a loss, Despite being fawned over by a human woman. For Koro~sensei, Who always expresses himself through his facial colors... What sort of face does he have for bewilderment?' Nagisa calmly observed the octopus. And as if on cue, Koro~sensei looks at Irina's breast making his face turn pink.

'THAT'S JUST YOUR RUN-OF-THE-MILL LOVESICKNESS, ISN'T IT?!' The whole class thought as Nagisa put in his notes the octopus's #5 weakness: Boobs

"Ahh... You're more wonderful everytime I look at you. Those lovely, Righteous-seeming round eyes, Those indistinct joints... I seem to have become captivated by you~ 3" Irina hugged Koro~sensei tighter even more... (That's what she said *inserts lenny face* )

~Timeskip to the whole class playing with Koro~sensei~

"A school hiring an assassin is problematic. We'll have you work as a teacher as well, To keep up appearances." Karasuma looked at Irina.

"...Fine. It doesn't really matter to me either way. I'm a professional. I'll hold lessons and all that, But the job will be over soon enough." She replied to him.

"Koro~sensei!" She approached him as the whole class stopped their movements to look at her. She asked him a favor to buy her a Vietnamese coffee which he immediately did and flew away to Vietnam.

"So...Um... Irina~sensei? Class is starting, So should we return to the classroom?" The raven-haired ikemen politely asked

"Class..? Oh right, you are all free to do what you want." The whole class looked at her in confusion

"And also, Could you guys just call me by my first name? Call me 'Jelavic~oneesama'" She took her cigarette and lit it

"So, What now? Bitch~neesan?" Karma broke the silence while the whole class snickered at her new nickname.

"DON'T SHORTEN IT BRAT!" The bitch exclaimed.

"You're Nagisa Shiota right?" She walked up to Nagisa. He nodded before getting kissed by the bitch herself

"WHAA- NOOOOO! KAYANO~CHAN IS THE ONE WHO'S SUPPOSED TO TAKE HIS FIRST KISS!" Lemina comically cried as she can now see that her OTP is now broken.

"YEAH! WAIT... WHAT?!" Kayano looked at her with a very surprised look. Lemina suddenly jolted up and looked at her.

"...Did you just agreed with me?" She smirked along with Karma and Rio as they saw Kayano's flustered face

"Come to the faculty office after this. I want to hear the info you have on that guy" Miss Bitch whispered to Nagisa as she broke the kiss

'Oh I see... No wonder she kissed him...' Lemina thought as the 2 went to the faculty office

"As for the rest of you!" All eyes are now staring at the bitch

"Those with useful information, Come and speak with me!" Lemina raised a brow at her

"I'm doing you all a favor. And I'll even lend some manpower to the girls. A professional's job lies in having both skill and personal connections. You brats should sit on the sidelines and watch" Now the whole class is a bit offended on what she just called them.

"And, If you get in the way of my assassination mission even, a little bit... I'll kill you." Miss Bitch threatened as she takes out her golden pistol

'Wow, She really IS a Bitch...' Lemina narrowed her eyes on Miss Bitch direction.
