Assassination classroom // Lemons and Oneshots

💙Itona x Yandere!F!Reader💙

Okay quick heads up.
PLEASE DON'T DO ANYTHING Y/N DOES, SHE'S UNSTABLE.

You were madly in love with Itona, obsessed with his every aspect of his being.
Every feature,
Every breath,
Every movement.
It was as if he was made for you, to fix your broken soul.

You made your feeling known to him at a young age, but that resulted in a restraining order.

But now, the 3 year restriction was gone and you finally could see him again.

~~~

"You no longer are the guardian of this child, huehuehue" Koro-sensei mocked to the annoyed Shiori, who was complaining about Itona's lack of tentacles.

"You've disappointed me, Itona" Shiori grumbled in irritance, Itona lacked reaction per usual.

"Just leave already, old man!" Nakamura laughed.

"Leave Itona alone!" Isogai defended.

"Don't bother me" Itona stared blankly.

"You've forced me to do this, Itona" Shiori stated coldly, Itona looked up with acknowledgement.

"Now, what do you mean by that?" Koro-sensei asked in confusion, in a threatening tone.

Shiori chuckled lowly, before raising his hand to the door.

"Please welcome your new classmate" Shiori introduced.

"Another assassin?!" Maehara yelped.

"Oh god! Not another one.." Okajima whined.

"The new student, she's coming today?!" Koro-sensei remembered.

"How is a new student threatening to me?" Itona questioned monotonously.

"Come in, Y/N" Shiori ordered, emphasising your name.

Itona's eyes widened in shock, he stood up from his desk.

In walked you, a beautiful and excited girl.

"Itona~" You hummed, placing your hands on your cheeks in happiness.

"Good morning, Miss Y/N!" Koro-sensei welcomed, your words quickly changed.

"Don't fucking talk to me, octopus" You chirped giddily, your tone almost threatening with its high pitched tone.
Everyone shuddered, besides the edgy ones.

"Itona, my darling! I missed you so much!" You cheered as you ran to him with your arms open, Itona cringed and went behind his chair.

"Itona, who's this weird chick?" Terasaka asked in annoyance.

"She's so pretty~" Okajima mumbled.

"Don't talk to Itona so casually" You growled in aggravation, Itona grit his teeth.

"I had a restraining order, you can't be here" Itona stated, staying behind his desk.

"Restraining order?!" Nagisa squeaked.

"Ah,ah,ah, that ended exactly yesterday! Isn't that amazing, now we can be together!" You squeal on excitement, taking his arm and wrapping him in a hug.

He stood still uncomfortably, you hugged him tightly.

"Hug back or I'll kill everyone in this fucking room~" You confidently hummed, he froze in place and put his arms on your back.

Everyone was confused and scared, besides the obvious red-head.

"What the hell is wrong with this chick?" Terasaka asked.

"S-she's scary..." Okuda mumbled.

"Don't ruin the moment, me and Itona have much to discuss! Don't we, my love?!" You squealed, jumping in place and bouncing.

"You need to leave" Itona instructed.

"Oh no no no! I'm staying here for a while! How about we go to (Itona's fav cafe)!" You giggle and he flinched, realising you knew his favourite cafe.

You loved him, so you followed him everywhere.
You knew about whatever he did.
His favourite diners, cafes, restaurants.
His parents, his siblings, his first pet!
His old friends, his new ones, his now dead ones.

"Surprised, Itona? We're going now, bye everyone!" You pulled Itona from the room, giving everyone a warning glare before leaving.

"That's playing dirty, Shiori" Maehara whined, because bringing in ANOTHER crazy child was starting to get tiring.

"Where Itona fails, she'll succeed" Shiori added, getting ready to walk out.

"She seems too focused on the boy for the octopus, doesn't she?" Karasuma said bluntly, Shiori chuckled lowly.

"That's why I brought her"

There was a pause of silence as Koro-sensei gave a quiet 'hm?'

"She'll do anything for Itona, even if it means people die" Shiori said before leaving the now silent room.

~~~
'You'll get whatever you desire with Itona, just follow my instructions and you'll live out your little fantasy.'

You gripped on Itona's arm, he grit his teeth in discomfort. You focused entirely on him, his eyes, his scent, his appearance and his breathing, that was slightly hitched and quick.

You got the icecream for him, making sure his eyes laid on no one else but you.

People admired your beauty, gawking at your stunning appearance. To others
seeing you with Itona was strange, which confused him seeing as you could've stalked any other attractive male; but you absolutely adored him.

You fed him spoonfuls of icecream, he ate them reluctantly. His expression was cold, but you were always chirpy and excited.

You ate from his spoon, savouring the taste of him in your mouth, he blushed. He quickly averted his eyes, mumbling about your obsession.

"Itona you have ice cream on your lip~" you point to his lip, using your thumb to wipe away the delightful ice cream and he blushed once more.

"Don't do that" He ordered, averting his eyes, you giggled teasingly.
You licked your thumb, tasting the sweet ice cream and fantasising about it being on his lips.

You truly did love him.
He couldn't help but be fond of you.
