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

You faced off against the demon. A thicket of poison flowers grew around you, trapping you in place. The demon smirked as the vines began to crawl up your torso. You weren't having any of that.

"Mist breathing! Second Form: Eight-Layered Mist!" You shouted, jumping in the air and slashing at the demon. It's head rolled on the floor.

"NO FAIR!" He cried. You watched coldly as he disintergrated to dust.

"Pathetic" You said, licking the demon's blood off your blade. You had a strange obbsession with drinking demon blood, but no-one knew why.

"I'd better get back to Muichihiro-sama" You realized. You were his tsuguko, and unlike most people, you weren't ashamed of someone younger bossing you around. This helped your friendship with the forgetful boy. You headed back into the forest in the direction of the Mist mansion.

"I kinda wish a stronger demon would appear. This is getting repetitive" You mused to yourself. You heard a cracking sound fron the side of the path, and stopped to listen. You weren't prepared for the blade at your neck from behind you.

"You use mist breathing, correct?" Said a husky voice next to your ear.

"Y-Yes, i do"

"Is your name Tokito?"

"I- no, I'm Y/N L/N" You emtally slapped youself for telling your name to someone who was bout to kill you.

"Huh. I thought mist breathing was unique to the Mist hashira" You nodded,"I'm his tsuguko" The swordsman removed the blade from your neck, pinning the tip to your back.

"Do you know who I am?" You shook your head and turned towards him slowly, only to be met by 3 pairs of eyes. The middle ones with the Kanjis: 'Uppermoon 1'. You gasped. This was none other than the strongest Uppermoon uppermoon, second to only Michael Jackson- Sorry, Muzan.

"Upper 1" You whispered. His blade was now pointing to your throat. He narrowed all his eyes at you.

'Thats creepy' You gulped. For a second, he took his concentration off you to look at your blade, and you took the oportunity to run. You were one of the fastest slayers, even faster than your own mentor. But this was the top upperrank. He took off after you, but the adrenaline and hysteria had given you a head start. But your luck ran out as you came to the edge of a cliff. No way you could survive the jump.

"You've given me a lot of trouble, you know" You heard the Uppermoon say. You faced him, trembling as you foresaw your own death in the near future. But still you faced him.

"Oh?" He said, his blank expression turning to mild surprise for a moment. This reminded you of your own dear mentor, Muichihiro Tokito.

"You're facing me? Bold. You're not even a pill-" You didn't let him finish as you plunged your blade into his throat. Blood exploded from his lips as you shoved your blade deeper. You got knocked back by a strong hand. You swung your blade at him at immense speed, slicing his hand off. But why wasn't he using his own katana?

"Immpressive. Especially when you took me by surprise. But it's my turn now" You were suddenly dangling from thin air, as he was holding you by your jaw over the precipice. You coudln't slice his arm off, so you swung at his torso instead. He tightened his hold on you until you heard a loud crack. A tremendous pain followed. You tried to scteam, but couldn't.

"Remember this as a warning. My name is Kokushibo" Uppermoon one said in his deep voice. He dumped you on the ground, and took you sword. Within seconds he'd vanished. Then you realized all the small cuts you had, especially over your arms and neck.

'Well, time to visit Shinobu' You thought.

"My my, you really fought Uppermoon one!" Said Shinobu as She and Aoi bandaged you up. You nodded. The bandages on your face felt itchy. Muichihiro was just staring at you, having come from his mission with only a cut arm.

"Yeah I-" You winced as you spoke, your cracked jaw hindering you.

"Did you say his name was Kokushibo?" You nodded at Aoi's question.

"We have to tell master this info. Thanks, Y/N-san" Shinobu smiled as she stood up.

"You're-" You got cut off by Aoi shaking her head, "You need to stop speaking"

You were on the porch, looking out towards the wisteria tree. You slowly started walking towards it, but when you were halfway there, you felt someone behind you.

"I didn't really mean to hold you that hard..." Kokushibo said, looking at you blankly. You shook your head.

"Why'd you-" You stammered," Not... Kill m-me?" He cocked his head slightly.

"I couldn't. I don't know why" He answered. You realized that he wasn't coming closer than 6 feet. Probably the wisteria smell.

"You need to.... to leave. Th-they'll kill... you" He smiled slightly.

"They can try" He took something out of his pocket and gave it to you. You, surprised, took it. It was a simple red hair pin, in the shape if an 'x'.

"Uh..." You really know what to think now.

"Wear it. I'll know if you ever take it off, it means you're in truble"

You looked at the tall Uppermoon. The crecent moon was right behind him now.

"Thank y-you, Kokushibo"
