"I'm impressed of how calm you are, Byakuya," Kenpachi Zaraki stated, "very admirable. But let's have some fun! Of course, if you're not careful, you might lose your head!" He snickered.
"Oh? I don't even think that youm Squad 11 Captain, have enough skill required for that," Byakuya replied.
"Why don't you test me then?"
"Shall I?"
"My pleasure." Kenpachi vanished without a trace while Byakuya focused his spiritual pressure. Kenpachi swooped behind him, becoming visible. Byakuya elbowed him in the gut, keeping him off course. Suddenly, Byakuya made blades pop out from the ground and said these words: "Waste him." The blades focused wind, enough to send Kenpachi flying into the air. He disappeared again.
"Where the hell are you?" Looking around, confused, Byakuya hit something hard with the back of his head.
It was Kenpachi.
He focused his spiritual pressure as fast as possible, and in that, a humongous blast of yellow fire came from Kenpachi's body and hit Byakuya hard. "I'm not finished yet," Kenpachi muttered loudly. He focused more energy, so much energy, that even a buldozer couldn't hurt him. He had become stable; with that, he had become practically invincible until it wears off. "Yachiru! Come!" Kenpachi ordered.
"What? That's not right! She's not a captain! She's a stupid girl who is almost five years old!" Byakuya commented.
Suddenly, a pink-haired small girl came from the buildings surrounding Kenpachi and Byakuya. "I'm REEEAAADYYYY to FIIIIIIIIIIGHT! WOOOHOOO!" she screamed as she came falling down. "And I'm not stupid or five. I'm six, and you've made me really..." she started focusing her energy; "really..... MAD!!!" Suddenly, a burst of yellow flames in the shape of a tiger's head jolted right out of Yachiru and hit Byakuya hard.
Suffering the pain, Byakuya struggled to say, "I.... cannot.... b-be.... defeated...." He dropped his zanpaku- to. "Bankai."

Both Kenpachi and Yachiru dropped to the floor. "Damn... I want to... become stronger... rrgh..." Kenpachi angrily stated.
"Hmph. All your talk was meaningless. Rather than my head, it was your pride of being a captain that fell." Byakuya replied.
"Come back... here...." Kenpachi struggled to say.
"Hey, boss," Yachiru asked, "do you.... think.. we'll ever...." she stopped talking and her harsh breathing.
"Yachiru? YACHIRU?" Kenpachi pounded her heart. She was dead. "I WILL KILL YOU, BYAKUYA!!!!!!"

"Hello, Sajin," Byakuya said, "it's me, Byakuya."
"Hello, Byakuya," Sajin Komamura replied, "Admirable skill, befitting the captain of Squad 6. I will be our next foe. I must avenge the death of Yamamoto. You are held responsible. And, as captains, let us now put our ranks to the test."
Byakuya grinned a small grin. "So we risk our honor as Captains? Compared to my honor as a noble, that is useless. But, if you insist, I'll make this quick."
Byakuya and Sajin ran toward each other, drawing their zanpaku- tos out of their scabbards. They held them high, about to strike each other. Instead, their zanpaku- tos clanged against each other, while Byakuya was pressing ultimate force.
SHNGG
Sajin's zanpaku- to shattered in two, leaving only Sajin himself. "You shall pay, for both breaking my zanpaku- to, and killing YAMAMOTO!" He then unleashed... "Bankai!"
Just then, a huge, black monster covered in purple- ish armor appeared and started blasting Byakuya and hitting rocks against him. "GRAAAH!!!" the monster screamed. He took his fist and tried to slam against Byakuya. He missed.
"That's it.. I'm ending this..." He dropped his sword. The word, the one word said, was: "Bankai."

He dropped down, almost dead. "My loss... you.. preserve the.. honor... of... many generations... of... Kuchiki... nobles..."
"That is to be expected. You are still at the point where your Captain's rank is the source of your pride and honor." Byakuya replied.
"Good... bye... Byakuya...." Sajin's heart stopped. His blood stopped moving. His breath was discontinued. All Byakuya could say was, "Damned idiot."
