Well that's how it all looked, but due to certain circumstances she was sentenced to E-class. This wasn't to great for (name) causing her family to need to 'discipline her, flipping her perfect angel image to a fallen angel of darkness.
So here she was waiting for her teacher to call her in, yes she was aware of the situation about the world ending if they couldn't kill her, but she didn't care, she just needed to get out of here. (Name) was called in by the octopus to which she strolled in, she looked to her class bowed and introduced herself, she knew 2 from this class Karma & Nagisa. She lazily threw her knife at Korosensei missing him widely "a little more effort ms (l/n)" said girl flinched "please just call me (name) I don't like my last name, by the way, where do I sit?" "Between Itona and Karma please" she merely nodded taking her seat.

(Names) POV

You were taking notes, the bell rung signalling lunch, you walked up to Korosensei "sir do you possibly have high school questions I could answer during lunch?" You could visibly see Korosensei's tears and your new classmates jaws hit the floor. "Of course (name) here you go" "thank you" and with that exchange Korosensei left while you went to your desk starting them.
You could hear your classmates comments "over achiever much" "is she even eating" "I know she's almost pure bone it's creepy" "I feel like if I touch her she's snap" frustrated you spoke "if you must all gossip, please make sure the person is not in the vicinity to hear" everyone gasped while you finished the last question.
You had left the papers on Korosensei's desk whilst you walked through the forest, you can upon a small stream, sitting at it you looked in, you saw your reflection "ugh how disgusting, positively unattractive....when was the last time you ate you disgusting thing" as you continued to insult yourself you didn't notice a presence until it nudged you. You jumped at the sudden contact and turned seeing a little black kitten. What a peculiar little thing "what are you doing out here?" It only meowed at you, feeling distressed thinking it would die on its own, you picked it up.
Walking back to the class with the kitten, you heard something rustle in the bushes, turning you saw Karma, you waved than continued to walk as he followed you to class.
you sat in class with the cat on your lap stroking it, it purred away. Nagisa walked up to you "em (name) why do you have a cat?" You looked at him rather bored "found it" he just nodded walking away.
Once Korosensei zoomed back in he saw the cat on your lap "(name) no animals in class" "I found it outside, would you rather I leave it out there to die?" You raised your brow as Korosensei began to panic as the others whispered "n-no it's just that no I wouldn't want any animal to die" "this coming from the guy planning to blow up our earth?" "Well um- oh name you finished ur question let me just correct these, don't be too upset if they were too advanced" Korosensei quickly corrected the questions, he gasped saying "100% there all correct..." you smiled perfect scores again that was when Karma walked over to you "why are you here if you have the intelligence of a high schooler" you squirmed in your seat, "just...personal reasons" "what kind of personal reasons?" This guy just won't quit "the kind thats none of your damn business." Before Karma could open his mouth Korosensei interfered "class is begging please sit down students" everyone sat and began class, you didn't have to worry about the kitten it just slept.
Class ended and everyone left, you stayed a little longer and studied until Korosensei walked up to you "not ping home (name)?" You looked up "oh sorry sir I'll leave now goodbye!" You stood up walking away as Korosensei frantically spoke "no I jus- that's not what I meant.. you can stay" you only bowed "I understand sir" and walked off.
