Things aren't progressing very quickly, and there's major OOC-ness on Mukuro's part. (B-but I did it for the lolz?) Review, please.

Chapter One

Once upon a time, far, far, far, faaar away, there was a young, doting father of three daughters.

The oldest daughter was Reboko, a short, rather…strange young lady with rather…violent interests. The second oldest daughter was Tsunayoshi (Tsuna for short), a wimpy kid who strongly admired Kyota, the cutest guy in the village where they lived. The youngest daughter was named Chrome, a quiet girl quite devoted to her father.

One sunny morning, their father, Mukuro got bored of their peaceful life in the village of Namimori and decided to go on an adventure. He packed his bags and mounted their old horse, Kenchikusa.

"Kufufu~ I'm sad that I have to leave my darling daughters, but I'll be back soon~!" Mukuro sang dramatically as he rode into the sunset. "But worry not, for we shall meet again!"

"Don't look down on me!" Reboko shrilled after Mukuro, chomping on her hair.

"Goodbye, father, and good luck," Chrome mumbled.

"Hey, isn't it morning…?" Tsuna asked.

Mukuro sighed and used his hand to shield his eyes from the persistent rays of the sun. He had been travelling for so long (nearly six minutes, darling), he was so tired (blinking was very tedious), and he was so thirsty (that barrel full of water didn't help at all)!

"This…is it…" he panted, slumping over in his seat and clutching at the air. "My life is flashing before my eyes…I never got to- hey, is that a pineapple?"

Suddenly full of energy, Mukuro perked up and steered Kenchikusa towards the previously mentioned fruit that had been abandoned at the side of the road.

"You poor, poor, thing…!" he cooed, leaning down and snatching it into his arms, where he cuddled it and gently rocked it back and forth. "Don't worry…daddy's got you now…kufufufu…you're safe, my sweet little Pineapple-chan…I've got to get you to a cooler!"

Now, with rekindled passion in his heart, Mukuro abandoned his previous mission- to have fun- and instead devoted himself to getting his Pineapple-chan to a cooler. As he rode on, journeying across the wide, paved road that seemed to go on for hundreds of miles, he suddenly became aware of how hot it was again.

Some nice juicy pineapple right now would be heavenly…wait! No! What was he thinking?! He couldn't eat his sweet, innocent Pineapple-chan!

"Papa is so sorry for thinking like that…!" Mukuro wailed, hugging Pineapple-chan tight and wincing when her spikes drove into his cheek. "Papa would never eat you, oh no."

But as Kenchikusa plowed on, Mukuro was tempted to peel Pineapple-chan with the trident he always carried with him and relieve him of his thirst.

Soon his craving was at its peak.

"I'm sorry, Pineapple-chan!" he cried, and brought out his trident. "I shall honour your sacrifice!"

As he stabbed into Pineapple-chan and devoured her, he swore he heard someone gasp, 'cannibal!' He paused, then ignored it and tearfully threw what was left of Pineapple-chan behind him.

Now that Pineapple-chan was gone, what would he do? After some careful contemplation, Mukuro decided to just ride on a bit further then head back. It was too late to make huge plans, anyways.

Mukuro was mourning over Pineapple-chan and didn't notice the dark, angry clouds roll in above him until it was too late. Plop, plop, plop. He could feel the rain starting to fall, and decided to press on further to seek shelter. Mukuro nudged Kenchikusa into a run. In the distance, he spotted a building and hurried towards it. Mukuro made it just after it really started to pour and invited himself in. The door was unlocked. He shooed Kenchikusa in and slammed the door behind him.

The horse immediately trotted off in the dimly lit foyer, leaving Mukuro on his own. The first thing he noticed was a yellow bird that was missing most of its feathers perched on a stool next to the door.

"Hibari, Hibari! Intruder, intruder!" it sang, over and over and over. "Hibari, Hibari! Intruder, intruder!"

"Hibari?" Mukuro muttered. "Is this place owned by birds?"

"Wrong," someone hissed behind him. Mukuro could feel something long and cool slide beside his neck and slowly turned around to get a better look at it.

"Oya, oya? Tonfas?"

His gaze slid up the arm of the tonfa wielder and across the taut shoulders, stopping at the face. Delayed reaction: three seconds.

Three.

Two.

One.

"OH MY GOD! OH MY GOD OH MY GOD OH MY GOD!" Mukuro squealed, latching onto Hibari in a sort of tackle-glomp hug. "YOU'RE SO CUTE! AHH! SKYLARK-KUN! SO CUTE! SO HANDSOME! SO-"

"Shut up or I'll bite you to death," Hibari growled, his steely grey eyes narrowing in annoyance. He attempted to shake Mukuro off, and when that didn't work, he tried smacking the man on the head.

"KYAA! BITE ME TO DEATH?! PLEASE DO! I WOULDN'T MIND IF SOMEONE LIKE SKYLARK-KUN DID~! Ow! What was that for, Skylark-kun?" Mukuro looked up at Hibari with misty eyes, his bottom lip stuck out in an unmistakeable pout. There was blood spurting out from the side of his head where Hibari hit him.

"This is my school," Hibari hissed, jerking away. Mukuro's tentacle hands unlatched from his uniform and he fell onto the polished floor with a muffled thump. "If you stay, you'll have to obey my rules. Got that, pineapple bastard?"

Apparently, that comment had struck a nerve in Mukuro. His eyes turned from childish and playful to cold and menacing in 0.01 seconds flat. Looking down so that his hair hung in a curtain in front of his face, Mukuro slowly stood up and pulled out his trident. Hibari tensed, ready for battle.

"Pineapple…bastard?" Mukuro whispered, staggering towards Hibari. "Pineapples…Pineapple-chan…Kufufu…"

When he looked up again, one of his blue eyes had turned red with the kanji for 'six' replacing his pupil. Creepy.

"Don't ever insult Pineapple-chan, you bird freak," he muttered ominously, his face inches away from Hibari's. He was smiling sweetly, but there was a dark aura surrounding him.

Hibari sighed and glared at the ground. What was it with him and yandere guys?

"So!" Mukuro leaned back, and the dark aura around him faded. His eye returned back to its normal blue. "Can I stay here for the night…oh, my! I don't even know your name! I just heard part of it from that half-naked bird over there." He pointed at Hibird, who had been forgotten in all the ruckus. "I'm Rokudo Mukuro."

"Get out." Hibari ignored the man's greeting and raised his tonfas. He started attacking, eventually cornering Mukuro at the front door.

"W-wait!" Mukuro whimpered, peering out of a window behind Hibari. "It's pouring out! My daughters will be horrified if I get sick! A-and I don't wanna get wet! My hair! It took me forever to mould it into this unique pineapple shape! A-and my horse already made himself at home!"

Mukuro pointed over Hibari's shoulder, and Hibari peered into the darkness behind him before leaning to the left and flipping a light switch. Ceiling lights buzzed, blinked, and finally shone, illuminating a grand hall with rows of lockers and a staircase off to the side. In front of one of the lockers, Kenchikusa had made a pile of steaming dung and then settled beside it, resting. Hibari's eye visibly twitched before he turned away and muttered, "You'll have to clean that up later, herbivore."

"So, can I stay here?"

Hibari surveyed Mukuro for a second before quickly stepping back and sauntering over to the staircase. At the bottom step, he turned back and smirked.

"Yes…but the price will be that I get one of your daughters."

Yandere (male)/yanderekko (female)- basically, it's a term used to describe someone who seems sweet on the outside, but is actually a psycho. Example: Ivan Braginski from Axis Powers Hetalia. :D
