Sanemi nodded, immediately jumping back into the fight. F/n took in a deep breath, ignoring the growing pain all over her body.

Breath of Moon, Tenth form: Dance of the moon spirit!

F/n slashed Kokushibou many times, he was busy fighting off Gyomei, Sanemi, and Muichiro. He still noticed her, he even landed a blow on F/n a few times, but he couldn't keep up with her quick movements while also fighting the other three.

All of them were bloody, Muichiro had one hand and definitely wouldn't last much longer, but they all were going to fight until they were shredded to pieces.

All of them fought with everything they had, not waisting a single movement. Kokushibou was reading their movements and was sending attacks in multiple directions.

Kokushibou sent out another powerful slash attack, causing all of them to be thrown off and stand stunned.

Using the demon slayers frozen body's to his advantage, Kokushibou sent out an even more powerful slash attack. How many of those did he fucking have? It's like he had an endless amount of power.

Gyomei chucked one of his prayer beads at the demon, causing him to become distracted for a moment. Gyomei used this chance to swing his flail, tearing the demons arm off.

Then Muichiro stabbed his sword through Kokushibous torso. Sanemi and F/n rushed in, along with Gyomei, to finish the upper moon off. It was now or never.

Genya was around the corner, pointing his Nichirin gun at the demon. Genya had eaten parts of Kokushibou, giving him other worldly power and strength. His gun had morphed into something like Kokusibous swords, it was littered with eyes.

Genya shot the bullets at Kokushibou, it pierced through his arms and thick large vines grew from out of Kokushibou, entangling him along with Muichiro.

Now that the demon was stuck, the demon slayers prepared to deliver the final blow.

Breath of Moon, third form: Selenian whirl!

F/n spun, swinging her swords towards the demon in the attempt to finally end him. But before any of them made contact with the demon, slashes came from all directions out of his body. Slicing Muichiro and Genya in half.

F/n, Gyomei, and Sanemi were able to avoid the attack. F/n stared at her friends body's, rage now flowing through her.

"YOU FUCKER!" She yelled in a fit of rage, gripping her blade tightly as it turned a shade of red, what seemed to be a crescent moon formed on her left cheek.

Breath of Moon, final form: Mirror of Misfortune, Moon lit haze

F/n's body flew at the morphed demon, slicing his limbs clean off.

"You shouldn't be able to use that form! What the hell!" Kokushibou yelled.

"Gyomei! Sanemi, Genya! If you're still alive you'd better help!" F/n screamed at the top of her lungs, continuing to attack Kokushibou.

Genya shot another bullet at the demon, vines forming around him once again.

Gyomei and F/n tore his head off, F/n sliced clean through his neck while Gyomei smashed his upper half with his flail.

Even though they smashed his body with all their strength, he still was able to regenerate it, turning into an even scarier morphed demon.

Right as F/n was about to slice him up again, using every bit of strength she had left. He began to crumble at the stomach. F/n sliced off his head, sending it flying somewhere.

His morphed body fell to the ground, slowly fading away. F/n was still able to stand even after using her final form. She stood in front of her great ancestor as he slowly evaporated, she put her hand on what was left of his shoulder, keeping it there until nothing was left of him.

All that was left of the Upper Moon was a flute, that seemed to be cut in half. F/n held it in her hands, enclosing it in her palm. She then stood up, walking over to Muichiros remains. Gyomei was by his side, praying for him to pass on safely.

F/n stared at him with sorry eyes, tears falling down her bloody cheeks. Sanemi was by Genyas evaporating body. Since the demon was dead, the effects began to wear off from Genya.

Sanemi cursed at the gods, telling them not to take his little brother away from him, not to take the only family he had left away from him. His uniform was stained with blood, F/n felt a mix of emotions coming from him. He was angry, he felt great loss, he was scared, he was sad, and what overpowered all of those emotions, was guilt. He felt immense guilt of not being able to protect Genya, he felt as if he failed as an older brother.

Gyomei stood in front of the grieving pillar, Gyomei was angry. F/n walked over to the two of them, blood covered her as well.

"Get up," Gyomei said sternly, "It's not over until we kill Muzan."
