a deal with the devil

With Kuruta and kurumi

Kurumi was still in the hospital bed sleeping the night away as Kuruta was they're sitting on a chair next to her bed.

Kuruta had his arms crossed and slept as he wasn't going to leave her alone.

By early morning

Kurumi had slowly opened her eyes as she slowly got up and saw her brother next to her.

"Kuruta what are you doing here? Should you be with your daughter?" Kurumi asked as he didn't respond to that answer because he was still asleep.

Kurumi tapped him on the shoulder and he slowly woke up to see her, she asked the question again and this time he responded.

"No she's with her grandparents for the day, I couldn't leave you here alone," Kuruta said as he hugged her.

"Do you know if my son's okay?" Kurumi asked as she was wondering where her son was right now.

"He's also with his grandparents since Sasuke was going to keep training all night trying to perfect his breathing styles," kuruta said as Kurumi wasn't all that happy hearing that.

"It's always about training and becoming stronger with him," Kurumi said as Kuruta was just annoyed.

"Honestly I don't know why you married him," Kuruta said as Kurumi just look at him.

"Because of the arranged marriage by father so the Uchiha clan could rebuild itself and sadly it seems it's not happening," Kurumi said as Kuruta remembered that day.

"Oh yeah that makes sense, back in those days we used to be the big talk of this whole village and now many had just forgotten about us honestly I wish we can go back to those good old days," kuruta said as he hugged his sister.

Both hope that things would eventually get better for them soon.

Later with kushina

kushina had both of her grandchildren in her arms as she was sitting on the couch with them.

Both have just looked a press, kuruto little girl had held her little fox plush tightly around her arms as Kurumi son was just resting.

kushina was happy for both our grandkids could visit her but it wasn't all that fun since neither of them like to play all that much and always were just scared and shy.

It was sad for her to see her grandchildren always like this, "don't worry you two Grandma's here."

Kushina hugged them as they smiled at her.

Later with Kuruta and kurumi

Kuruto and Kurumi had both left the hospital and went over to kushina.

When both got there they saw their kids I'll gain their grandmother and sleeping.

"Thanks, Mom for watching them," Kuruta said as he sat down next to his daughter as Kurumi sat down next to her son.

"Don't mention it I love spending time with my grandkids," kushina said as Kuruta and Kurumi picked up their children and put them on their lap.

"Hey, Mom where is Sasuke at?" Kurumi asked.

"He went out in the forest to train by himself," kushina said as Kurumi had had it.

"mom, Kuruta I want to get a divorce," Kurumi told them both.

Both jumped up in surprise, "a divorce WHAT!?"

"You both heard me I cannot stand being married to him anymore, he doesn't want to be a father or a good husband, I want to get a divorce as soon as possible," Kurumi told them as she put her sleeping son down and went to find Sasuke.

Later at night with Sasuke

Sasuke was alone in the forest training by himself, he was exhausted but kept training.

"COME ON WHY WON'T MY POWER UNLOCK!" Sasuke yelled as he tried to use his breathing style on a tree as all the rage and fury was getting to him.

Sasuke couldn't stand for it, couldn't stand being the last member of his clan to live and die, he couldn't stand that all the chakra and ninja jutsu was gone even his clan bloodline abilities of the Sharingan was gone, all of this, becoming a demon Slayer he tried to became the best swordsman and became the well respected throughout the village but none of it was enough for him as he kept training so hard to become the strongest until the one final slash he gave using all his strength left he finally unlocked his demon Slayer mark.

His demon Slayer mark was dark purple lighting covering half of his entire body.

It was great but all of a sudden he dropped to his knees and started to cough off blood.

"Damn it!" Sasuke yelled as someone had appeared right in front of him.

Sasuke looked up and saw that look like a samurai, he had six eyes with two of them having the symbol of upper Moon one, long black hair, a purple kimono, and black pants, with a sword in his arms.

"Who the hell are you?" Sasuke demanded to know as he know this man was not human but he didn't have the strength to get up.

"Hello Sasuke Uchiha, I am Kokushibo, I have witnessed a lot of your skills and I must say you are quite impressive," Kokushibo said as he bent down to look at him.

"You're an upper Moon, are you? Why are you here?" Sasuke asked as he wanted to know what was his reasoning.

"Simple I'm searching for humans to become new demons and I have found you, would you accept my offer of becoming a demon?" Kokushibo asked Sasuke growl.

"Why the hell would I become a demon!?" Sasuke told him as he would never become one.

"I know many things about you, there have been other demons that told me about you how about you hating the fact that you are the last Uchiha to have the sharingun and lose it, as well the thought of your clan being gone with everything else you have lost everything and you want to have it back, I could help you or just let you die here after all that demon Slayer Mark you have finally awoken and it's seen your past the age of 25 you would be dead before sunrise, if you do become a demon you would live forever and could continue practicing your skills to become the strongest swordsman," Kokushibo asked as Sasuke did want to become strong and didn't want the legacy of the Uchihas, there's no way his son could since he never had the showing on nor would ever rise to become a swordsman or be any kind of Shinobi to carry on that legacy.

After a moment Sasuke had made his choice, "very well I accept your offer," with that Sasuke was given demon blood.

"If you can survive from this amount you'll become a demon," Kokushibo said before he left him alone to transform.

With Kurumi

Kurumi was in the forest walking down the road to where Sasuke would usually train alone at.

It wasn't rare for him to go to the spot to train alone at, she knew him way too well, once you got there though she saw her husband on the ground in pain and in agony.

"SASUKE!" Kurumi yelled as she ran towards him but quickly stopped when she noticed something was wrong very wrong.

With Sasuke

Sasuke in his mind

All that He could think about it was becoming stronger and to regain his old powers of the Uchihas once more.

Remembering all his loss, what happened to his clan many years ago, what happened to his revenge that could never happen, remembering feeling to bring back the clan, remembering losing his powers, remembering everything he couldn't get back, you want power and everything else didn't matter him.

Sasuke started to transform.

His skin became pale as white, his hair turned stripe white and red, his eyes transform to red as he stored regained his lost abilities the Sharingan, his hands became more like claws as he grew by afoot.

"Sa-sas-sasuke?" kurumi was in horror and shock.

Sasuke slowly got on both of his feet and looked at her, "you and that bastard child were a waste of my time!"

"Why would you say that to us, especially to your son?" Kurumi asked as he never called their son a bastard before.

"Pathetic and useless you both were, see things so much clearer now, my time of being a demon Slayer is over, you have no value even being a meal as your weekend pathetic," Sasuke said and then quickly vanish.

Kurumi couldn't believe it, there was no way Sasuke could have accepted a deal with the demon to become one.

Kurumi headed back home to tell the others and now this was not going to be good news for anyone to hear.

To be continued

So Sasuke is a demon now.

The demons slayer has just lost another demon Slayer.

Many things are going to soon change and not for the good.
