Mysterious Transferee (Assassination Classroom Reader-Insert)

A new teacher is being introduced to the class by Karasuma-sensei. And even though the unusual first impression she had with the class because of her getting oddly close to the other teacher, it really is no mistake that she's very beautiful. "Meet your new temporary foreign language teacher." Karasuma-sensei lets the new teacher continue.

"Irina Jelavić. Nice to meet you." Irina-sensei greets while hugging one of Koro-sensei's tentacles. The students have a deadpan expression as they watch the new teacher, they notice some hearts floating around her.

"Who would've thought you were a teacher here?" Irina-sensei asks Koro-sensei as he removes his human disguise.

"This school wants to give you an authentic experience in foreign languages. I hope there aren't any complaints about her taking over half of your English lessons?" Karasuma-sensei informs and looks at Koro-sensei who agrees without hesitation.

"We've got a new teacher. Not only that, she really seems to like Koro-sensei." Kayano tells Nagisa, who nods in agreement.

"I might get some assassination hints out of this." Nagisa said as he takes out his notepad and observes the target. 'His face has so many colors, so what color is bewilderment?' Nagisa thought.

Koro-sensei's face turns pink with a blush making the students sweat drop while thinking the same thing. 'He's smitten. There's no mistaking that face. How human of him.'

"The more I look at you, the more I like what I see. Your beady eyes, like two diarrhea pills. Your undefined joints. So captivating!" Irina-sensei compliments before she hugs him more, making her chest be felt better by the undoubtedly perverted octopus.

"How embarrassing!" Koro-sensei exclaims, still having the same face, just proving that he is currently what the students had observed.

'Don't let her trick you! No one finds those attractive!' Okano and Nakamura thought.

'We're not dense. Any teacher assigned to this class at this time has a probability of being no ordinary teacher.' Nagisa thought, doubting the real intention of the new teacher.

'She's going to work here? If so, I wonder how she'll try to kill him. Gotta talk to her later.' Y/N mentally reminds herself and sighs, already wanting the day to end.

After the introduction, the students go outside and play 'Pass and Kill' with Koro-sensei.

"Hup! Pass! Hup! Kill!" The players exclaim and while the students are busy playing, the other two teachers are still inside the room. Irina-sensei looks at them through the window as Karasuma-sensei approaches her.

"I already prepared all kinds of close range methods... I never thought my seduction tactics would work." Irina-sensei informs her colleague before she takes out a cigarette and lights it using a lighter.

'Irina Jelavić. Profession: Assassin. Not only beautiful, but she has a dozen languages at her command. She can bewitch a target from any nation and even kill highly guarded targets from close range with ease. She's an assassin with a fine handle on infiltration and approach.' Karasuma-sensei thought as he reached her.

"But you can't just hire an assassin to work here. You need to teach to keep up appearances." Karasuma-sensei retorts as he looks at her when she walks toward the door leading outside.

"I'm a pro. My job will be done before I resort to teaching." She remarks before opening the door, giving a glance at him before going out.

"Hup! Pass!" Koro-sensei exclaims while he passes a soccer ball to Karma.

"Hup! Kill!" Karma also screamed out before he kicks the ball back at him as he also shoots his gun. Koro-sensei dodged the incoming bullet.

"Hup! Pass!" Koro-sensei exclaims again and catches another ball from Okano.
