Blood Moon

They had done it. They had defeated Muzan Kibutsuji. The remaining Slayers celebrated their victory, cheering and hugging their remaining comrads. Kakushi darted around, hurriedly treating the wounded and collecting the remains of the fallen Slayers.

Giyuu leaned against a wall whilst Kakushi treated his wounds.

"Tanjiro! I need to find Tanjiro!" Giyuu yelled. He tried to push the Kakushi off him but they held him down with a strong grasp.

"Giyuu! You shouldn't be moving in this state! Just rest for now, let your body recover," One of the Kakushi yelled at Giyuu whilst struggling to hold him down.

Though even in his wounded state Giyuu managed to push the Kakushi off him and started to run around, looking for Tanjiro.

"Tanjiro! Tanjiro!" He yelled out for Tanjiro. He needed to see if his friend was okay. Giyuu ran into a clearing and there he saw Tanjiro's limp body, barely holding onto his katana, head facing the floor. He was surrounded by six Kakushi, all sobbing hysterically. Giyuu held his breath and skidded across the floor, head pressed against Tanjiro's forehead.

"No, no. Tanjiro," Giyuu whispered, trying to hold back tears. But he couldn't stop them flowing out of his eyes. They flowed down his cheeks like small waterfalls.  He gripped his uniform tightly. "Tanjiro, I'm so sorry I couldn't protect you," He muttered, choking on his own words.

--------------------------------------------------------------------------------------------------------------------------------

Tanjiro opened his eyes, where was he? He mustered the strength to turn his head to the left. What? What is this? All Tanjiro could see was a pink sickly flesh for miles and miles. He tried to sit up but something was holding him down. It was the flesh.

"Gi- Giyuu," Tanjiro weakly muttered, "Giyuu San, where are you?"

--------------------------------------------------------------------------------------------------------------------------------

One of the Kakushi wiped his eyes and peered down at Tanjiro's face. 'What? I swear he had a huge piece of flesh on his face before.' Suddenly Tanjiro's missing arm grew back in an instant, with large sharp claws, ripping the Kakushi's face covering and scratching his face. 

"Ta-Tanjiro?" The Kakushi stuttered.

Giyuu jumped back dodging Tanjiro's arm. "TANJIRO! WHAT ARE YOU DOING?" Giyuu yelled.

Giyuu waited for him to respond but all that came out of Tanjiro's mouth was a low, menicing, malice filled growl. Tanjiro's eyes burst open. Giyuu gasped in horror. Instead of being met with the hope filled maroons eyes of his friend he was met with a sickly pink, cat slit eyes. This wasn't Tanjiro anymore.

Giyuu unsheathed his katana and stood in a fighting stance, the Kakushi gathering behind him. "Everyone! Gather your weapons! Muzan has turned Tanjiro into a demon!"

Everyone gasped in horror. What!? But Muzan had been defeated! How could he possibly have turned Tanjiro into a demon?"

Tanjiro licked his hand like a cat. He turned to Giyuu and smiled a malice filled smile. Waterfalls of drool dripping from his mouth.

"Tanjiro... If you're in there, fight him off!" Giyuu said determendly.

--------------------------------------------------------------------------------------------------------------------------------

"Giyuu san......." Tanjiro weakly said, "I'm sorry, but I'm just so tired."

"Tanjiro," A deep voice echoed, "Just give in already, there is no point in fighting, I've already won."

Tanjiro recognised the voice. It was Muzan's. "No," He replied "I won't give in, I want to go home with Nezuko. I want to see my friends faces again."

"But Tanjiro," The voice chuckled, "You killed them, you killed your friends." Muzan knew it would be easy to manipulate Tanjiro in this state, he is already so tired. He just needed to push him to his limit.

"No, I didn't," Tanjiro muttered, "I can hear them, they want me to come back to them, And I want to go back to them."

--------------------------------------------------------------------------------------------------------------------------------

Giyuu hoped, he hoped that Tanjiro would come back to his senses after hearing his words, but instead all he heard was a laugh, a horrible, evil laugh.

Before Giyuu could lunge at Tanjiro he noticed something. The sun, we can burn him.

Tanjiro continued his evil laugh untill he noticed Giyuu's smile. He turned around to see what he was smiling at. Tanjiro gasped, the sun. Before he could leap to shelter he felt the burns. They hurt so bad.

"AAAAARRRRGGGGGHHHHHH!!!!!" He shreaked in agony. He collapsed to the ground sqwerming around like a rabid beast. His skin grew red blotchy burns all around.

This was it, this was Giyuu's chance to kill him. He leaped towards the screaming Tanjiro, pining him down. "I'm sorry this is the way this has to be."

Tanjiro hissed and snarled at Giyuu, his fangs visible. Then suddenly it stopped. The burning had disapared. "No," Giyuu whispered. Tanjiro swang his arm towards Giyuu flinging him across the clearing.

Inoske ran over in a hurry after hearing all the comotion, "TANJIRO! CUT IT OUT!" He yelled.

"Hahahahaha," Tanjiro giggled.

"WHAT'S SO FUNNY?" Inoske screamed angrily. That's when he realised he had open wounds, and they were actively bleeding. Tanjiro Pounced like a tiger towards Inoske. He covered his face, trying to protect himself from Tanjiro's wrath. That's when he heard a loud CRUNCH. He moved his arms away from his face to see Tanjiro biting deep into Nezuko's shoulder.

"Onii san," Nezuko whimpered, "Don't give in, don't let Muzan win."

Giyuu raised his head from the rubble. "Oh no," He gasped, "He's tasted blood, all hope is lost."

Suddenly, as if he was evolving, Tanjiro sprouted tenticals from his back. They swang around in the air wildly making surrounding buildings crumble.

"Onii san! Stop! Come back to us please!" Nezuko pleaded.

Kanao watched the chaos unfold from a distance. "How sad, I feel sorry for both of you," She sniffed. Then she remembered, She remembered Shinobu giving her a vile of medicine.

"Kanao, I'm not sure if Nezuko will turn back into a human in natural terms," Shinobu explained whilst handing Kanao a vile, "Use this on Nezuko. It will turn her back into a human, though there is only enough for one injection."

Kanao felt around in her pockets for the vile, she felt something wooden scrape the back of her hand. She took it out of her pocket. It was the medicine. Thank god she didn't lose it during the battle.

"I see, this is why I have one eye left," She said softly with a smile. Flower breathing, final form; Vermillion Eye! She aimed the needle to Tanjiro's back.

SPLAT! One of Tanjiro's tenticals had smashed Kanao against a wall, destroying the vile in the process.

All hope was lost, they had no chance of winning now.

"I'm sorry Onii san, I'm sorry you have to suffer," Nezuko cried. Tanjiro looked up at Nezuko with a confused face. Then, like a drop of rain one of Nezuko's tears fell on Tanjiro's forehead.

Tanjiro dropped Nezuko, Giyuu rushed in to catch her. "Nezuko..." Tanjiro whispered, his eyes reverting back to his normal self for a moment. Then as if a fly was hovering around his head he started to wave his arms in the air. Then as soon they reverted back to normal they changed back to the pink cat slit eyes. 

Giyuu looked closely at Tanjiro's face. That's odd, I swear I just saw him crying.
