Dear Little Flower - Sanemi Shinazugawa x Reader

I'm speechless at this. And I'm the author. [Yooo!!! YOOOOO!!!! YYOOOOOO!!!!! I CANNOT EVEN WORDS WHAT IS JUST HANEEPP]

"GIVE ME MY SISTER BACK!!" Koichi cried as he and Kokushibi exchanged attacks, his movements were sloppy and he was acting on emotions, Kokushibo noticed it. "Give her back to me! Return her to normal fuck-eyes!"

In all his life, the one thing Koichi wanted was to repay you and protect you. But...

How come all these time he's failed and did nothing but put you in danger.

He was a failure as a brother.

Why does he always fail?

He felt like his own life was taken from him when he saw his sister struggling within the hold of the demon that has been wanting to kill you and him for a long time now.

Why can't he be the one that turned into a demon, why couldn't he be the one that the demon wanted to kill, why couldn't he just be better?

"WAKE UP YOU BRAT!" Sanemi exclaimed, taking Koichi by his collar and pulling him back. "Don't just go running off by yourself!! You'll get killed!"

"Isn't that better... my sister is already..." Koichi choked up on his sobs. He couldn't accept reality and Sanemi has had enough of him. Sanemi raised a hand and slapped him across the face and tossed him to where Muichir and Genya were. 'Ow. That hurts.'

Sanemi. He's seen his mother turn into a demon and he watched as his siblings got killed one by one, only managing to save his little brother at the nick of time. The price of it was him killing his own mother.

And he was lost in the dark, he finally met someone, he found you, who guided him and showed him the beauty of life. A life that he thought he didn't deserve. He wanted you to live happily and peacefully.

He wanted to fight for you and Shiro, for you two to have a better future where there are no demons.

But...

But there you are, suffering right in front of him.

And he can't do anything about it. He can't turn you back to normal. You were turning into a demon the more he took his time with the demon. The more he and Kokushibo fought, the closer you were becoming the thing he swore to destroy.

And there was only one thing he could do now. He needed to kill you before you could do something you might regret.

But can he do that?

No. Of course he can't! His last memory of you was you two fighting! How can he end everything without even apologizing! It nearly tore him apart when he killed his own mother, imagine how he would feel if you, his own wife, would have to die by his own hands.

There was no chance he could do it.

He won't do it.

Shiro was still waiting for you to return. He can't let his son down. He was sure Shiro already hated him more than enough, imagine if he hears that his own father killed his own mother.

'Dammit! I don't want to kill her!' He thought to himself, moving out of Kokushibo's attack. 'I can't kill her... please, God, don't take someone from me anymore...'

But he knew that he had no choice. Either he will kill you or someone else will do it.

'I'm sorry, (Y/N)...' Sanemi stopped in his tracks, changing targets. He gritted his teeth, already regretting what he was about to do. He gripped his sword with an iron grip and raised it above his head, his tears blurring his vision as he struck down.

Finally, he could end your suffering. Finally, he can let you rest peacefully. But... 

not everything goes according to what one wants.

Koichi stumbled and struggled to stand up straight after Sanemi threw him to the side. Muichiro strutted to him and helped him stand up, placing him next to the still cup up Genya.

"Hey, your injury's bleeding..." Muichiro said, pointing to where Kokushibo stuck his sword before you appeared. "You need to close it up."

Koichi nodded, reaching for a bandage inside his uniform and treating his bleeding arm. "Hey... how are you going to get back together, Genya?"

"I just need something from a demon..." Genya replied, looking over where his brother and Kokushibo were fighting, and where you were currently resting, unresponsive from the battle. "(Y/N)-nee... she's..."

There was a heavy silence as they frowned. They saw the fear in your eyes the moment you saw Kokushibo, they saw how scared you were when you faced your greatest fear. And now... if Sanemi didn't kill you, you would turn into a demon and be forced into someone they would have to kill.

They didn't want that.

They didn't even want you to be here in the stronghold of Muzan.

"Why... why her...?" Muichiro asked, his eyes glossing as he watched the battle. "Why did he even want her..."

"Because we can make him stronger..." Koichi answered, remembering their entire history. "He did this once already. Twin brothers. He turned one into a demon and... took the other for himself..."

There were no more words exchanged as they tried their best to recuperate and join in the fight.

But, just as they were watching, they saw how Sanemi changed his direction, going after you.

Their eyes widened in surprise, Koichi immediately stood up, taking his sword.

'Nee-chan is... going to get killed...' He thought, freeing himself from Muichiro's hold. But before he could even escape Muichiro, Kokushibo protected you from getting killed. 'Huh... what is he doing...'

"You cannot kill her just yet." Kokushibo said, lashing an attack to Sanemi, managing to hit him and push him back, his blood dripping on the floor. "(Y/N) may be able to recover but... hm-?"

"Catnip for cats and marechi for demons..." Sanemi chuckled, blood spurting from his mouth as he grinned. "Demons get drunk once they get a whiff of my blood!! And this blood is the rarest of the rare, once-in-a-lifetime shit!! Now have a fucking feast!"

Sanemi jumped back into action, doing his best to avoid the attacks and keeping his organs inside where they belong. His target didn't change. He needed to... get you to rest.

Before something worse occurs. 

"I see that you're still after her..." Kokushibo said, keeping Sanemi on his toes. "But I cannot let you do that..."

"And why not huh, your burning crap shit." Sanemi spat, holding his ground and doing his best to get to you.

"I'm afraid that... even if you manage to harm (Y/N), she can heal but..." Kokushibo paused when he saw movement. He immediately went to your side, his sword, blocking Sanemi. "The life growing in her will not."
