The demon stared at F/n, "I haven't heard that name in a long time..." He said, his voice was calm but it shook the ground.

"You have the same aura as that boy over there..." He said, pointing to Muichiro. He'd been impaled and pinned to a pillar.

"Tokito-Kun!" F/n yelled, staring helplessly at him.

"Ah, I see now. You're my second descendant..." He muttered.

"There's no way I'm related to a monster like you..Gramps had to have been lying" F/n mumbled, holding up her blade.

"Chose your words carefully, little one. And i don't go by Michikatsu anymore, the names Kokushibou " He muttered.

F/n growled, "Shut the fuck up!" She yelled.

Breath of Moon, tenth form: Dance of the Moon spirit!

F/n flew at Kokushibou head first, using nothing but her pure strength and emotion to fight. She maneuvered herself under him once he attempted to slash her. She tried to cut his legs, but he jumped up and dodged the attack.

Breath of Moon, Eleventh form: Moonlight through bamboo, Drilling slashes, eleventh consecutive strikes!

F/n slashed Kokushibous body, leaving cuts over his face and neck. This caused Kokushibou to draw his katana, revealing the most disgusting blade F/n had ever seen.

"What a disgusting blade, the fuck is that!" F/n scowled, trying to push her blade closer to his chest.

"I see you use moon breathing...what have my descendants done to it..it's nothing like the way I created it to be." He muttered, sending F/n flying into a pillar.

'Breath of moon, fifth form: cursed vortex of the ghostly moon'

Without swinging his blade, Kokushibou sent three powerful slashes towards F/n. She jumped just in time, avoiding the deadly attack.

Breath of Moon, third form: Selenian whirl

F/n spun towards the upper moon, deflecting his attacks once again. She was able to land a blow on the demon, slicing off his hand, which did absolutely nothing. He regenerated instantaneously, landing a blow on F/n.

"I'm surprised someone as young as you possess this much strength, that equivalent to a pillar.." Kokushibou muttered, continuing to send attacks towards F/n.

"You should become a demon.." He proposed, looming over F/n's beaten up body.

F/n chuckled, "like hell I'll do that.." she said.

Breath of Moon, Sixth form: New moon

F/n put all her power into her legs, being able to move around swiftly. She ducked behind pillars and landed tiny blows on the upper moon, he stood in the middle of it, watching and listening carefully.

F/n was about to deal another blow on him, when he grabbed her by the neck.

"You've had your fun, time for me to have mine." He said, his grip around her neck getting tighter.

"S-Sanemi..!" F/n yelled as loudly as she could.

Almost as if on cue, Sanemi flew at the demon, slicing off the arm that had F/n in its grasp.

"Hey fuckwad! I'm your opponent here!" Sanemi yelled, a devilish smile on his face.

"Get up kid, this one's tough!" He yelled, kicking F/n lightly.

F/n nodded, standing up and readying her blade.

'Breath of wind, third form: tree swaying in the mountain air!'

Sanemi slashed at Kokushibou, the upper moon doing the same. F/n took this opportunity to land a blow on the demon.

Breath of Moon, ninth form: Reflected sunlight!

F/n went for the demons legs, being able to slice one off but missing the other. Kokushibou jumped back and looked at his severed limb.

"That strike..it slowed my regeneration.." he muttered as his leg soon regenerated, "maybe your type of Moon Breathing isn't as useless as I thought.."

'Breath of wind, purifying wind..!'

Sanemi attacked the demon once again, causing him to go on the defensive. F/n took a deep breath in.

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

This time, F/n went for the head. Her blade was about to make contact with his neck, but she was shot back.

'Breath of Moon, sixth form: The eternal nights solitary moon avici'

Kokushibou sent tons of slashes in all directions, slicing up Sanemi and F/n. The pillars around had collapsed, Sanemi and F/n stood still, trying to take in everything that just happened.

"Your skills are impeccable, you guys held up for quite some time. Bravo. But if you move now, your organs will spill out.." Kokushibou warned.

F/n tensed her muscles, the cuts she had weren't deep enough to slice her open, but enough to have her bleed out. She wasn't sure about Sanemi though.

F/n felt the demons increased pulse, she glanced at Sanemi who held another devilish grin on his face. He pounced at the demon once again, and they engaged in another bloody battle.

The demons moves slowed every so slightly, F/n heard Sanemi yell something about his blood. Maybe that was the cause of the sudden slowing in attack power.

"Are you just going to stand there forever, F/n!? This fights far from over!" Genya yelled, desperate for someone to help his older brother.

F/n gripped her blade, she'd already stopped the bleeding of the nearly fatal wounds Kokushibou had given her. She coagulated her blood with her breathing to keep herself from bleeding out, a trick she learned from Kukuyomi.

F/n took another deep breath, "It's time to end this."
