Abusive Yandere Yang x Male husband reader x Wife Leone

The final battle

Y/n P.O.V~

I walked with my wife hand in hand to the car as we got it and drove off. It was time we ended this. Enough is enough. I don't want to wake up, always wondering if I am safe or if she is going to come after my kids or my wife. I didn't want Leone to get kidnapped again. Yang Xiao long, this is your reckoning. Your death...

Leone P.O.V~

I sat next to Y/n as he drove the cat towards our destination. My darling has a look that was a mix of worry, sadness, and anger, all simultaneously painted on his face. I placed my hand on him as he looked at me and smiled. I returned his smile as we looked on, continuing to drive towards Y/n's former lover. I looked at my hands as they changed into firsts. My darling, my love, my husband, I won't let her hurt you again. I swear...

Thirdperson P.O.V~

After three long hours of toll's traffic and long driving, the Husband and Wife duo had reached the evolution tower in vale. Y/n and Leone parked their car and exited it. The couple entered the building and found an elevator Leone pushed the top floor's button as the elevator rose, and the husband and wife left the elevator, then found a staircase leading to the rooftop. Once Leone and Y/n had reached the rooftop, they saw her. Yang was waiting for them. Yang's red eyes glowing as a sadistic grin was plastered across her face.

Yang:" So, I see that you want to stay with Leone."

Y/n:" Correct."

Yang looked at Leone and smiled.

Yang:" Well, then."

Yang got into a fighting stance as the claws that jutted out from her monstrous grim arm grew in size as she let out a roar. Leone and her husband got into a fighting stance as well, Leone activating her semblance and Y/n getting out his weapons, purple flames engulfing the claws. Leone and Y/n charged at Yang and began to attack each other. Leone attempted to punch Yang in the face but was stopped when Yang gripped her arm and threw her back. Y/n grew angry as he swung his weapon and Yang. One of the claws slashed across her right cheek, making blood trickle down her face and onto the ground. Yang grabbed the chain of Y/n's weapon and began to swing him around as Y/n clung to the second claw of his weapon, the chain snapped, sending Y/n flying off the top of the tower and plummeting to the ground below. Leone screamed out her husband's name; Leone looked at Yang in anger as she screamed out in rage and began to attack Yang. Leone punched Yang rapidly, doing her best to damage Yang as possible, but Leone punches did not faze her. Yang grasped Leone's leg and threw her across the top of the tower. Leone got up and reached into her pockets and grabbed a pair of aura pricing brass knuckles, the same pair of weapons that she had used all those years ago when she and Yang fought for the first time. Both blonds charged at each other as they once again began to exchange punches. Leone's punches now began to make Yang bleed as her weapons were able to hurt her. Yang grew furious as she once again grabbed Leone as she threw Leone off the top of the tower. As Leone fell to the ground, she was scooped up into her husband's arms.

Y/n, now in his devil form, flew up to the top of the evolution tower and landed, letting Leone out of his grasp. Leone and her husband charged at Yang and began to fight. Yang was overwhelmed by Leone and Y/n's attacks. Yang had managed to rip off Y/n's devil wing's when he was unprepared. Y/n let out a screak of pain as he reverted to his cat Faunus form. Leone grew angry as she began to punch Yang over and over rapidly. Each blow that landed onto Yang made even more blood spew out of her. Yang landed on the ground, and Leone was about to land the killing blow, but Yang moved her head, making Leone's fist go into the top of the tower. The tower began to shake and crumble apart; y/n rushed to save Yang, but Leone stopped him.

Leone:" What are you thinking."

Y/n:" Leone, I don't like it either, but she is still a person! We have to save her!"

Leone looked down and nodded, but Yang spoke, saying something that shocked the couple.

Yang:" You two get out of here."

Leone looked at Yang with a shocked look on her face.

Yang:" Get out of here; the tower is going to collapse! Run both of you run!"

Y/n quickly changed back into his devil form and got Leone on his back as they flew off.

Yang P.O.V~

As the tower collapsed, I fell. I saw my life flashing before my eyes. When Y/n and I first got together. Every time I was sick, he would take care of me; he was always trying to make me happy. He was the best boyfriend. He was the perfect man. I cried as I smiled as I dropped to the ground. Y/n, I am thankful for the time we had together. Rubble from the tower began to fall onto me, crushing me. I never deserved you, and as I cling to these last moments of life, I'm sorry, and I know that I don't deserve your forgiveness and that I deserve to die. I'm sorry, my love; you always smiled the brightest. Thank you, Y/n...

Thrid person P.O.V~

Leone and Y/n were holding hands standing in front of Yang's grave. Leone was three months pregnant, and Y/n had just asked something.

Y/n:" Leone, can we name one of the twins, Yang?"

Leone looked down as she thought about it.

Leone:" Alright, but why if you don't mind me asking."

Y/n:" Well, I think it's an excellent way to remember who she was, not who she became."

Leone:" What do you mean?"

Y/n:" I would like to remember nag before she went insane. As a girl who wanted to have fun, enjoyed hanging out with friends and who loved her sister very much."

Leone smiled as she gripped her husband's arm.

Leone:" I like that idea, but I get to name the boy."

Y/n smiled while looking at his wife.

Y/n:" I think that's fair."

Unknown to either of them, the spirit of Yang looked down on both of them and smiled. Yang looked at the happy couple as her form disappeared as she spoke.

Yang:" I promise to always watch over you and your family forever..."
