Soon after the events of Fusion Finale: Byakugo and Kenpachi's & Unohana's wedding….
Soul Society: Near Squad 11

"Hey!" Yachiru squealed as she jumped into the air, her fingers just grazing the bag of candy that was being dangled out of her reach. "Gimme' back my candy!" she ordered.

The purple-haired werecat grinned from ear to ear as she held Yachiru's bag of candy over her head, smirking playfully down at the girl. "Awww! C'mon, Yachiru! You can grab it if you really tried!" she teased.

Yachiru pouted with a cute face. "You meanie! No fair!" she said while stomping her tiny foot down. "You're too tall! Give it back! I want my candy!" she shouted, still trying to reach for the candy. In the distance sat Yumichika and Ikkaku, who simply shook their heads.

One of Yoruichi's new pastimes that she'd discovered was teasing Yachiru. Now that she had entered motherhood, she had become a bit more aloof and playful thanks to playing with her daughter, Masaki. After hearing about Yachiru's failed pranks with Kenpachi, Unohana and Ichigo, she'd stopped by regularly to tease the little girl for the heck of it. While Kenpachi didn't really like it, Unohana found it to be cute and let her do it as long as she didn't push too far.

"Awww! Looks like you're too short!" Yoruichi said, putting the candy behind her back. "Too bad, Little Yachiru! Only big girls can have their candy!"

"GIMME!" Yachiru screamed, lunging for it. But even someone as fast as Yachiru couldn't match Yoruichi's speed. She vanished from the pinkette's sight and reappeared on a nearby rooftop. Yachiru's ruby-red eyes gleamed with anger, making Yoruichi giggle.

"Maybe when you're taller you'll be able to get your candy! Later, Little Yachiru! I'll be spending my afternoon having me a sweet snack!" Yoruichi said before vanishing. She giggled as she ran from the lieutenant; she'd give the candy to Unohana like usual who'd give it back to her but seeing Yachiru get riled up was worth it. It was like teasing Byakuya all over again.

Ikkaku and Yumichika promptly made themselves scarce, knowing what came next. Yachiru stood there, tears coming out of her eyes before she threw herself onto the ground and threw a temper tantrum. "I WANT MY CANDY! I WANT IT I WANT IT I WANT IT I WANT IT I WANT IT!" she screamed, feeling more angry than she'd felt when Ultimate Kenpachi spanked her. "SHE'S A MEANIE! I WANNA BE TALLER! I WANNA I WANNA I WANNA I WANNA I WANNA I WANNA!"

This went on for about fifteen minutes….

Finally calming down, Yachiru picked herself up off the ground and dusted herself off. She wanted to be taller so that she could get back at Yoruichi but she didn't know how. It'd be years before she grew to her adult size and she didn't really trust Captain Kurotsuchi or Nemu to experiment on her. But then she remembered how when Ichigo had fused with her father, the result made him taller. "That's it!" she exclaimed happily. "I'll fuse! Then I'll show her!"

Walking away from the area, Yachiru entered the Senkaimon for Karakura Town, leaving her parents a note. Reaching the Urahara Shop, Yachiru sneaked inside. Kisuke had his back to her, oblivious to the sneaky girl, helping Ururu fill the shelves with candy. Yachiru made a mental note to come back here when this was over….

Tip-toeing to Kisuke's workshop, Yachiru slipped inside and looked around. The place was filled with assorted objects; beakers filled with liquid, tools that showed signs of heavy use, books filled with notes….

And a box of Potara earrings sitting on a table!

"Bingo!" Yachiru reached for the box and grabbed it, tucking it into her shihakusho before slipping out the window, opening another Senkaimon to return to the Soul Society….

Kuchiki Manor

The captain of Squad 6, Byakuya Kuchiki, sat on the wooden ramparts and watched the flowers in the garden sway in the breeze. Everything was going so peaceful, so smoothly that Byakuya felt at peace with himself….

"Hi'ya, Captain Kuchiki!"

Byakuya's brow furrowed in annoyance. Bad enough that he now had a good day interrupted but it was made worse since it was Kenpachi's annoying daughter, Yachiru. "What is it, Lieutenant Kusajishi. Do your parents require something of me?"

Yachiru shook her head before pulling out the earrings in her pocket. "Can you fuse with me?" she asked in a surprisingly nice voice.

Byakuya stared at her, wondering if perhaps this was a dream or if he had been hit in the head and this was all some messed-up hallucination. "Why do you want to fuse, Yachiru?" he asked.

"I wanna teach Kitty a lesson! So I wanna fuse and get taller so that I can get my candy back and pay her back for always picking on me!"

Again, Byakuya just stared at her. 'This is so childish it's not even funny…' "Lieutenant Kusajishi, I will not fuse with you. Go ask Ichigo Kurosaki," he said with blatant contempt added to the boy's name. "Fusing is his specialty."

"Ichi's too busy with Shark-Lady and little Masaki to help. Please?" she asked with puppy-dog eyes. "Kitty said she always picked on you too. Don't you wanna get back at her?"

'I believe I've already done that….' Byakuya mused. But then two things occurred to him: First, if Yachiru went blabbing to Kenpachi and Unohana, then Byakuya would have to deal with the wrath of an angry Unohana for refusing her stepdaughter such a simple request. And the last thing he wanted was to deal with an angry Unohana….

And second, Yachiru and Byakuya were two of the fastest Soul Reapers in the Soul Society. So if they were to combine into one person… they might actually be faster than Yoruichi!

Sighing, Byakuya decided to relent. 'I've no business with my squad today. And I suppose that the worst that will come out of this is that I'll have to be fused with Yachiru for a few hours. "Very well, just this once I'll fuse with you, Lieutenant Kusajishi."

"YAY!" Yachiru cheered, bouncing up and down. Walking over to Byakuya, she put one of the earrings in his hand before taking hold of the other one. "C'mon! Let's go find Kitty so we can teach her a lesson!"

Byakuya had a feeling this was going to be a looooong day….

An Hour Later….

Yoruichi lay on the rooftop, sucking on a peppermint she'd taken from Yachiru's candy bag. "I guess I should give the bag to Unohana before heading back home to Halibel and Masaki…."

"Hey Kitty!"

Turning her head, Yoruichi grinned from ear to ear when she saw Yachiru standing on the other side of the rooftop. Beside her was Byakuya, making Yoruichi raise an eyebrow. "Oh? What's this? You couldn't get your candy back on your own so you decided to bring some extra muscle this time?" she asked while sitting up.

"No! Byakuya and I are gonna fuse and we're gonna teach you to stop picking on me!" Yachiru declared, putting on her Potara Earring….

Yoruichi almost busted a gut laughing. 'Byakuya fusing with YACHIRU? THAT'S PRICELESS!' Standing up, she crossed her arms and cocked her head. "Byakuya, you sure you gave this more thought? You do know what happens when a man and a woman fuse together, don't you? 'A teenage transgender Byakuya? THIS has to be, by far, the best day of my life!'

"I'd figure I'd humor the girl for once," Byakuya explained. "And it also occurred to me that in a fused state, we'd be faster than you."

'So that's the real reason he's here….'

Continuing to stand there, Yoruichi watched in anticipation as Byakuya fixed his earring to his ear. Because they were standing so close together, they didn't collide like atoms in a particle accelerator like usual. Instead, Yachiru was lifted up and pushed into Byakuya's chest before they were engulfed in a bright flash of light. When the fused person floated down, Yoruichi had to fight the urge to laugh hard….

"Hah! Now I'm taller than you!" shouted the girl who walked over to Yoruichi. "Now it's time for…time for…." She didn't finish when she realized that she was still looking up to Yoruichi. Looking down at herself, the fused girl realized that she'd grown about maybe an inch in height! "What's going on?! Why am I not big?"

"Awww!" Yoruichi fawned, patting the girl's head. "Poor little Byachiru! You didn't pay attention when you grabbed those earrings, did you?" She leaned down and flicked the white earring on her left ear before flicking the black earring on her right. "Those earrings are specially modified by Kisuke. Instead of a full merger, it suppresses the mind and body of whoever wears the black earring. Instead of combining your body and mind with Byakuya's, you merely gained part of his personality, his abilities and a few of his physical features."

The newly christened Byachiru looked practically the same as Yachiru, but with only small differences. Her pink hair now had black roots and was a little longer. She wore Byakuya's scarf but still retained Yachiru's shihakusho. Senbonzakura now rested next to Sanpo Kenju on Byachiru's waist, albeit much shorter. Byachiru stomped her foot in anger reached for the bag of candy tied to Yoruichi's waist. "Give me back my candy! I'm still faster than you now!"

"Oh?" Yoruichi giggled as she jumped out of the way, grabbing Byachiru by the back of her outfit and yanking her up. "Who's faster than me?" she asked smirking.

"Hey! Let me down!" Byachiru demanded as she was dangled in the air, her legs kicking at the smiling werecat. "Put me down, right now!" she shouted, feeling the anger of Byakuya seep into her.

Yoruichi put a hand to her smiling mouth. "Awww! You look so cute when you're angry!"

"Grrr!" Byachiru reached for her zanpakutos. "Scatter: Senbon- MMMMPH!" Byachiru was silenced when Yoruichi reached into the candy bag and pulled out a large sucker, stuffing it into the pinkette's mouth. Now silencing the girl, she reached for her small swords and pulled them away, tossing them off the rooftop and leaving her defenseless.

"Now, didn't your mother teach you not to play with sharp objects?" Yoruichi scolded. "And you seem to have picked up Byakuya's temperamental attitude." Yoruichi frowned, making Byachiru scared. "I think your father and stepmom will forgive me for teaching you two a lesson in respect…."

"NONONONONO!" Byachiru squealed as Yoruichi bent her across her knee. "OWOWOWOWOWOWOWOWOWO!" she cried out in pain as Yoruichi spanked her. "OWOWOWOWOW!

'Byakuya's gonna hate me for this but it'd be totally worth it!' Yoruichi thought as she stopped. Turning her around, she looked at the crying Byachiru. "Learn your lesson, Little Byachiru?"

Looking up, Byachiru nodded, looking absolutely adorable to the mother. Patting her head, Yoruichi hugged her. "Awww! You're so cute! I'm sorry for spanking you," she said, holding the girl tight. Soon Byachiru's sobs subsided and the girl cuddled into the werecat's bosom, Yoruichi running her hand through her hair with all the compassion she'd picked up from being a mother. "Hmmm…I wonder... is our little Byachiru ticklish?"

"AhahahaAHAHAHAHAH!" Byachiru laughed as Yoruichi tickled her, squirming in the woman's embrace as she struggled to breathe. "Ahahahah! Stop that! That tickles!" she said in between breaths, giggling up a storm. Yoruichi grinned at Byachiru's reaction, loving how she was inadvertently tickling Byakuya at the same time.

Soon Yoruichi stopped. By this point Yachiru had tears running down her face, trying hard to calm down. Looking up, she gave Yoruichi her best puppy-dog eyes. "May I please have my candy back?"

Patting her head, Yoruichi decided to relent. "There," she said as she handed the bag to Byachiru. "I'm sorry." Byachiru dried her eyes as she cuddled into Yoruichi's chest. All the excitement was too much for the fused girl, who promptly fell asleep in her arms.

Yoruichi smiled at the little girl, deciding to stop teasing Yachiru from now on. Reaching for the Potara earrings, a lightbulb went off in her head. "Hmm…I wonder…. If Yachiru wore the white earring on her left earring and Byakuya on the right…."

Byachiru slept on in Yoruichi's lap as Yoruichi swapped the earrings fixed to her ears, reversing their positions. To Yoruichi's delight, a bright flash erupted from the girl, the fusion reversed.

The figure opened his eyes as he woke up. Looking up, he saw Yoruichi stare at him with a wide grin, as if she was seeing the greatest spectacle of her life. "Well hello there, Byachiru. Or should I call you Yakuya now?"

Now that Yachiru's mind was suppressed, it was Byakuya who had been given full reins over their fusion…and he did not like what he saw. Yakuya was in the image of Byakuya but with one…distinct difference….

….He now had long pink hair.

Yakuya turned to Yoruichi and scowled. "I hate you…."

"AHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAH!

The End
