The Devil Duo (Karma x Reader)

Part 4 (Grown-Up time)

Sitting in class already to learn like they "good" students they were, all of 3E wasn't prepared for a surprise visit from Karasuma. Despite that, all of them (minus Terasaka) knew that he only showed up during PE or whenever there was something really important that was about to happen.

"Well let's just get on with this. Let me introduce your new English teacher," Karasuma said, voice as monotone and low as ever.

"My, name is Irina Jelavich. It's wonderful to meet you all!" The voice as high pitched, too high in tone to be normal for a grown woman. Upon looking, the jaw on half the boys in the class dropped.

Body frame like a model, flowy blond hair, and piercing blue eyes. Dressed in all white clothes with a black blouse. It was like staring death in disguise except...

"What have you done to our new teacher?"

The question was asked by Chiba, but it seemed like everyone thought the same as they turned towards the h/c-haired girl int he back who looked at them with an innocent and curious look before-

"I haven't done anything to her. I barely know the old hag." Y/n said lifting an unimpressed eyebrow at their new teacher as her classmates had a chill go down their spine.

"Now, now Y/n-san. No need for such rash and harmful remarks." Korosensei said tentacles up in weak stop halt. While he did that the other students save for Karma tried to recover the sudden turn in personality.

Noticing their confused gazes Y/n sighed before leaning forward in her seat. "Did you really believe that I normally act like an 8-year-old girl?" She asked, making some flinch under her appraising gaze.

At their avoiding gazes, Y/n sighed. 'Morons, I'm surrounded by morons.'

Letting the thought go the h/c haired girl leaned forward in her seat.

"Huh? Vich, right? As in the Slavick word vich, or as in the word for a female wizard witch? How do I know that you are who you say you are?" She said smiling at their new teacher, who was currently glomping the yellow octopus teacher like a body pillow.

"No letting up the act? Pity, or maybe you're just that reluctant on giving up. I mean, who'd care if your dignity vanishes with the act. I do hope so, it's starting to hurt my eyes... physically." Y/n said lacing the last word with as much venom as a potent snake.

*Smack*

"Ow! Bf/n what the heck!?" Y/n whined rubbing her back head while looking at her best friend begrudgingly.

"You know what that was for, besides... you can't have all the fun." She said smiling as a dark aura settled on the two in the back. (And for some reason the aura around Karma was all rainbow and sparkles... JK)

Then completely shattering the tension in the room Y/n turned towards her PE teacher. "Neh, Karusuma-sensei? Why is this... individual here?"

"One of our school goals is to teach you abought foreign languages. That's why she's gonna take over half of your English lessons," Karasuma explained composed as ever, acting as nothing had happened.

'Mátame ahora, por favor...' (Kill me now please...) The collective class though looking at the sunshiny duo in the back row.

The lesson continued on as nor- as... unusual as the new teacher all lovey-dovey had Korosensei in a side hug, singing him praises.

Chewing her lip Y/n thought. 'I'm trying so hard not to kill her, in order to put her out of her misery.' Her gaze never leaving the grown woman who acted like a teen on love drugs.
