💙Yandere!Chisaki x F!Reader💙

Let me know if ya want more Yandere stuff. I'm a sucker for Yanderes 🤤💕

He was a sociopath.

You had figured this out through a short period of meeting him, in battle of course.

The way he lacked empathy, the way he pursued his goals without hesitation, his change of attitude to his obsession of staying clean.
Everything about him screamed psycho.

But despite being a selfish maniac who was only focused on his own goals...

He was madly in love with you.
To the point of mentally distorting you to do his bidding.

You had a quirk like Eri's, you could pause time on people and their quirks.
Therefore, he also used you as a test subject.

It didn't matter that you were hurt, you were angry that your little sister had to suffer the same.

~~~

"Go now...he can't catch you" You whispered to Eri, your younger sister.

"No...I can't leave you...he'll hurt Y/N-chan!" Erin whimpered to you, gripping your arm.

"Y/N-chan will be fine...go Eri!" You ordered, pushing open the door to her escape.

"I'm not leaving Y/N-chan!" Erin sobbed, feeling helpless and protective.

"Your big sister will protect you, I promise...Now go!" You spoke in 3rd person, trying to comfort Eri.

Eri gave a weak frown before running away with her bare feet, Y/N frowned in concern.

"Please...have a hero find her..." you mumbled.

~~~

"Where is she?" Chisaki asked, his voice tired but with laced danger hidden deep within it.

You stayed silent, looking away from him. It'd been 5 minutes since you let her out, perhaps she was safe now.

"Answer me, Y/N" Chisaki's bare hand gripped your jaw and made you face him, you gulped.

You were the only person he could touch for this long, because he knew you weren't filthy like the rest.

"I don't know..." you mumbled untruthfully, your eyes averting.

"You can't even lie correctly, why are you so eager to irritate me?" Chisaki questioned, gripping you a bit too harshly.

"Stop...Chisaki" You said unintentionally, making him grit his teeth in annoyance at the use of that name.

"I specifically told you not to call me that" Chisaki growled, his eyes darkening as the lump in your throats began to grow in fear.

"Sorry..." you muttered, gulping.

"Nemoto...your quirk" Kai ordered, Nemoto gave a 'yes master' before using his confession quirk.

"Where is Eri?" Nemoto asked.

You tried to cover your mouth but Chisaki pried your hand away.

"She ran away-" you shut your mouth and bit your tongue.

"So you were lying, just to protect your little sister. How heroic" Kai mocked.

"Leave her alone...she doesn't deserve this!" You yelled, suddenly he had reached for your shoulder and completely decapitated your arm.

You screamed in pain, the few moments of terror were soon silenced as your arm was regenerated.

"Watch your tone with me, darling. This disobedience of yours will only bring you suffering" Kai patted your head consolingly, a smirk forming under his mask.

You gripped your arm with a shaky breath, shutting your eyes forcefully.

"Stay with her, Nemoto. A punishment will be in order after we get back Eri" Kai looked down to me, enjoying the sight of me grovelling.

'Cruel..' you thought to yourself.

~~~

"Please...he's got my big sister...please don't go..." Eri begged to Izuku, whose jaw dropped seeing this girl.

"Pardon my daughter, kids these days always throw temper tantrums" Kai explained to Mirio and Deku.

"Why does she have bandages?..." Deku gulped, feeling the girl cling onto him.

"Eri is very clumsy, now if you'll excuse us. Eri...Y/N is waiting for you" Chisaki reached out for Eri, who only clinged to Midoriya tighter.

"Y/N? Is that your big sister, Eri?" Deku asked and Eri nodded.

"That's kids for you! Come on Deku!" Mirio hinted to Izuku, who only stared down to Eri.

"Did you...do something to this girl?" Izuku asked and Mirio sweatdropped with a gulp.

"Don't assume things" Kai walked off back into the alley, Eri ran straight to him as he began to take off his glove.

"See, she's fine. We'll be on our way now" Kai didn't look back.

"Hey wait!" Izuku was paused by Mirio.

"Stop Deku, we need to take it slow" Mirio suggested and Izuku grit his teeth.

"But that little girl-"

"He was about to get violent, she was protecting us, we can't do the same if we rush into things!" Mirio explained, putting a hand on Izuku's shoulder.

Izuku watched as the figure of Chisaki and Eri faded into the darkness.

~~~

You tucked Eri into bed, expecting a punishment from Chisaki.

At least Eri wouldn't be able to hear the sounds of your pain, you knew she was a gentle soul.

"One day, Eri..." you kissed her forehead, praying for her safety.

"Master is waiting for you..." Nemoto stated, almost feeling pity for you

You nodded, standing up and walking out the door. Better to take your punishment like a champ.
