Its shame you are not on my side.

Never Aizen..You will be brought to Justice.

Back For I see..Too bad you cant stand.

You dropped you guard.. your head belongs to me!

ALLY OR ENEMY

Aizen Sosuke stares intently at a blue orb in cave in Hueco Mundo, "most interesting...here..I thought you had died" he thought. Aizen turned to the arrancars that had found the orb, "Hao..Mao...good work...This will prove very useful" he stated. Hao and Mao bowed, when suddenly the blue orb started to surge with reiatsu and with a burst of wind it exploded, with a figure dropped near where the orb was. The figure rose seeing two people with purple hair and half their faces covered with white bone but the one standing behind them raised his ire. The figure growled as his blue and gold eyes flickered in anger, "Aizen!" he howled, as his purple-black reiatsu surged. The two arrancar stood in shock at the display of power, "hao..mao..attack him" aizen ordered. Hao and Mao drew their swords but before they could even blink, the figure was behind them and their bodies were in pieces. Aizen stood unfazed with his arms crossed, "I see your powers have not dimished...Kiriyu..Mitsuomi" he smiled. Mitsuomi glared with his face contorted in anger, "draw your sword...its time we finish this" he shot.

"Really..I think not" aizen shot back. Mitsuomi raised his left straight out, "Then...Begone from my sight" he stated, as a purple ball formed in his hand. Aizen raised an eyebrow, "a cero..interesting" he thought, dodging the cero and landing behind mitsuomi. Aizen stared intently as mitsuomi charged another cero but aizen vanishes as the cero collides with the cavern wall, blowing a hole in the side. Mitsuomi scanned the smoke for his target but before he could react a hand was in front of his face, "hakufuku" aizen recited. Mitsuomi's eyes widen as he felt his body go numb, "Chikusho" he thought, as his eyes went blank. Aizen stood mitsuomi with a smirk, "most interesting..indeed" he whispers, seeing mitsuomi in the light that entered the cavern.

Mitsuomi slowly started to stir, when he heard jeering and growling, "finally awake...Mitsuomi" a voice stated. Mitsuomi opened his eyes and took in his surrounding which was a large arena with two large doors on each side, "over here..pal" a voice mocked. Mitsuomi turned to see both aizen and ichimaru, "You..." he hissed and gin smiled.

"Mitsuomi..it been so long...and this how you greet me" aizen stated. Mitsuomi's eyes narrowed as his reiatsu started to spark, out of the corner of his eye he saw zetsuei in the ground. Mitsuomi disappears in a flash to grab zetsuei and charged aizen, "you're dead" he shouts, bringing his blade above aizen's head but is blocked by another sword, "you are foolish...soul reaper" a voice stated. The figure raised his left hand and charged a green cero. Mitsuomi barely dodged the cero landing a few feet away, "good work Ulquiorra" aizen stated.

"Are you unharmed Lord Aizen" ulquiorra replies. Mitsuomi watches as several more figures appear with various shapes and sizes but all carried sword, "they look like soul reapers but have cracked masks" he whispers. The group bows as aizen passes, "they are called arrancar...hollows that have blured the line between hollow and soul reaper..similar to you but You are a pale imitation...with these arrancar..I will destroy the soul society" aizen stated. Mitsuomi gripped zetsuei tight and brings the hilt to his left shoulder but the blade curved down, "don't you dare underestimate me" he hissed. Aizen chuckled slightly snapping his fingers and one of the large door opened behind mitsuomi to reveal dozens of hollows and arrancars, "defeat them...then maybe...you'll have the power to kill me" aizen stated, as he and his group vanished from the arena floor.

(song playing...Frenzied battle..bleach ost)

Mitsuomi turned to the charging hollows, "Tremble...Zetsuei" he uttered, zetsuei responded extending to six feet in length with a few ringlet of chain on the hilt. A rhino like hollow charged him but mitsuomi lept up, slicing it in half and barely dodging a swing from squid like hollow, slicing it into pieces. Mitsuomi drove his blade into a monkey hollow and quickly turned slashing a snake hollow in half. Mitsuomi leapt in the air holding his blade horizontally, "Kaze ryū Odori!" he shouted, as wind erupted from the blade slicing several holllows and arrancar. Mitsuomi then raised the blade above his head, "Kōri no ryū Odori!" he added, slamming the blade into the ground. A sheet of ice erupted from the blade, freezing several arrancar but a few dodged and released their swords. One arrancar charged a cero but mitsuomi held himself firm, the cero collided with his blade explodng but mitsuomi charged through the smoke, killing several more arrancars. The group watching were not impressed by mitsuomi's fighting prowess, "its futile..he is a fool" ulquiorra stated. Mitsuomi drove his blade into the ground and several spikes erupted from the ground, killing several and more appearing.

"Maybe but he's got chops for fighting like that..emo boy" stated a blue haired arrancar. Ulquiorra glared at the blue hair, "he's trash like you grimmjow" he stated.

"Fuck off" grimmjow retorted. The others interests were from eagerness to seeing him die to down right anger, "the fool..is an ant compared to me" stated an older man with one eye and a crown. A lazy looking man with brown wavy hair was lying on his side with a light green haired girl next to him, "hey Stark..that soul reaper..he seems weird...his arm?" she stated, pointing. Stark stares at mitsuomi's left arm as he punches a hollow, cracking its mask. The arm is pure white except for black fingers and strange markings, "I don't know Lillynette" he states, with a yawn. Stark however raises an eyebrow, when he sees mitsuomi's hollow like left eye. Gin watches with a sly smile, "he's improved since before but how much?" he thought. An ape hollow grabs mitsuomi from behind as several others charge their ceros. Mitsuomi struggles to get free as the ceros charge him, "no choice.." he whispers, as the ceros explode around him. Several arrancar cautiously approach as the smoke starts to dissipates but from the smoke, a purple cero obliterates three of them. The smoke clears revealing mitsuomi, now wearing a faceless mask with a purple lightning mark on the left side. Grimmjow cracked a wicked grin, while stark sat up for a better view. Mitsuomi slowly raises zetsuei to his right shoulder as the blade starts to howl, "Dragonstrike!" he bellows, driving the blade into the ground. The blast of blue energy charges from the ground, letting out a haunting wail as it rocks the arena. (song ends)

Mitsuomi turned to aizen as smoke leaks from his mask, "Your turn...Bastard" he hisses but he only stares, "I see...so you did aquire hollowfication but..do you really think its enough to kill me" aizen smugly states. Mitsuomi raises zetsuei to aizen, when a blast strikes his back knocking him to the ground. Mitsuomi grunts getting to his knees, "hahaha..got ya" a voice stated. Mitsuomi glares back to see a huge person with a bald head and a black ponytail, "Yammy..finish him" aizen orders. Yammy inhales deeply sucking in the lives and reishi of all the hollows on the arena floor. Mitsuomi plants his blade in the ground, "Tsuchi ryū odori" he recites, as a wall of earth springs up. Mitsuomi gets to one knee trying to stand, "damn that cero struck me good" he thought.

"Mitsuomi...we should escape..right now we are outnumbered" a voice echoes. Mitsuomi get to feet as yammy finishes, "can't zetsuei...nowhere to run...besides..we still got one ace to play" he thought.

"Hahaha...yea..so go bankai and wipe the floor with aizen and his cronies" a second voice states. Mitsuomi cracks a smirk under his mask as he raises zetseui overhead, "Bankai!..Kurai Heiki Zetsuei!" he recites.

(song playing...Encirclement battle..bleach ost)

The wind picks up on the arena floor as mitsuomi's reiatsu swirls around him, "a bankai...a mask and...a cero...you continue to amaze me mitsuomi" aizen thought. Grimmjow was grinning with excitement by the display of power, "still no match me..if I release" he thought.

"So this a second release of a soul reaper" stark thought. The others stared intently as the smoke vanished revealing mitsuomi with a menacing black scythe on his shoulder with chain wrapped around the base of the huge blade. Yammy cackled staring at the scythe, "so...trash..you got a new weapon" he mocked but stopped when mitsuomi flashed behind him. Yammy wailed in pain, clenching his shoulder where his right arm use to be, "Bastard...You're Dead Trash" he hissed, as his red reiatsu flared. Ulquiorra rose from his seat, "its fine..let yammy use his resurreccion...I want to test Mitsuomi's mettle" aizen stated and ulquiorra bowed sitting down. Yammy went for his sword as mitsuomi pointed his scythe, "what's the use of packing a sword...if you're not going to use it...Show me what you got arrancar" mitsuomi snaps. Yammy gripped his sword tight, "Enrage..Ira!" he bellowed, both his body changed and swelled in size. Yammy grew an extra set of arms as he grew to thirty feet tall, "guess...he couldn't regenerate that lost arm" mitsuomi thought, flaring his reiatsu. Mitsuomi skipped back dodging yammy punches and balas, "Raikurai ryū Odori" he recited, as lightning rained down from his scythe. Yammy swung a wide left but mitsuomi dodged landing on the other arm, "stand still..you fly" he bellowed but mitsuomi fired a flame from his scythe. Yammy roared colliding with the arena wall but countered by firing a bala, mitsuomi cut the bala in half but couldn't dodge yammy's fist. Mitsuomi flew like a missile colliding with the wall on the other side of the arena. Yammy charged a cero, firing it for good measure which destroyed half the arena. The group watched as yammy stomps toward the rubble, "well..its over..lets go Stark" lillynette states.

"Not just yet...I'm thinking...its not done" stark replies. The rubble starts to shake as yammy nears and from it hundreds of black chains, yammy struggles as the chains ensnare his body, "what is this?!" he howls. Mitsuomi emerges from the rumble to the shock of some of those present, his top is now gone completely, blood trickles down his chest and face from his cracked mask. Mitsuomi raised his right index and middle finger upward, causing the chains to ignite in a black flamed explosion. Yammy staggered as the flame engulfed his body, burning it to nothing but ash, "Konoyaro!" he howled, trying to charge mitsuomi but was met by a purple cero, "No You're Dead" mitsuomi stated. (song ends)

Mitsuomi turned to Aizen as zetsuei reformed in his right hand, "Now..Its your turn" he hisses, the others stand ready to intercept. Aizen rises from his seat taking one step, when a huge blade strikes mitsuomi from his left side. Mitsuomi's eyes widen as he falls to the ground and shatters his mask, "hurry up and die..I wanted to face you but you seem weak..now" a voice sneered. Aizen flashstepped to the arena floor to see two people, one with pink hair with glasses and the other with a large weapon and a eye patch, "Szayelaporro...Nnoitra...step away from him" he states. Nnoitra and Szayelaporro bow and take their places among the others, "Don't walk away from me Sosuke" mitsuomi hisses. Mitsuomi tries to stand but his breath is ragged as the blood drips from the wound in his side, "your chance at defeating me was a fleeting one" aizen states. Stark stares intently, "even now..still trying" he thought.

"He can not win...why does he continue?" a voice asked. Stark turned to see a young woman with long seafoam green hair, "I'm not sure..Neliel" he repiles. Neliel watches as mitsuomi clutches his sword but it hasd returned to its sealed form, "despite his wounds..he continues...strange" she thought, looking to see some of her comrades have left the arena with only her, stark, lillynette and zommari still watching. Mitsuomi charges aizen but he dodged each swing with ease as aizen drew his sword and slashed mitsuomi's left shoulder. Mitsuomi staggered and stood his ground but aizen flashed behind him slashing his back and left leg, "give...up...you have no chance of winning" aizen stated. Mitsuomi stood again with the help of his sword, "No Way In Hell" he spat but his eyes widen as a blade erupts from his chest. Mitsuomi clutched his chest as he fell to one knee with blood pouring from his mouth, "do you know why I fought you this time?" aizen asked. Mitsuomi struggled to stay standing, "I don't give a damn" he struggled to say. Mitsuomi finally collasped and rolled on to his back as he stared up at aizen, "you are interesting...you killed one of my espada...you survived our last encounter...your abilities...thats all" aizen stated, walking away but turned quickly, driving his blade into mitsuomi's chest. Mitsuomi stared wide eyed at blade in his chest as blood filled his lungs, reaching up mitsuomi weakly grabbed the blade. Before his eyes went blank, "Don't you Dare Die Today" a voice echoed.

(song playing...The battle is to the strong...Fate/Zero ost)

Aizen pulled the blade from mitsuomi's chest and stares at his lifeless eyes, "did you really have some notion you could defeat me..Hmm..I guess..I'll never know" he thought. Aizen turned his heels as his espada that had remained to watch appeared, "Lord Aizen..are you unharmed?" asked Neliel and aizen smirked, "He was to weak to harm..." he stated but stopped when the area was engulfed with a heavy reiatsu. The surge of power was enough to even push aizen back, "what the hell?!" lillynette shouted.

"I don't know?!" stark replies but he jerks, "Look..over there?!" stark adds, pointing. Aizen looks to see mitsuomi's supposed dead body standing as purple and black reiatsu swirled around him, "he was dead" aizen thought. Mitsuomi's blank eyes flew open as his body shook, letting out a distorted wail as he grabbed his sword charging Aizen. Mitsuomi appeared above aizen with his sword baring down but was blocked by Neliel and Stark's swords, "man..he's stronger than before" stark stated, as they pushed him off. Mitsuomi skidded to halt as white liquid started to seep from his wounds and a small black dot appeared on the right side of his chest and gradually got larger, "is that a hollow hole?" neliel thought. Mitsuomi howled raising his left hand and charging another more powerful purple cero, "what is the meaning of this..mitsuomi?!" aizen questioned but mitsuomi did answer as he fired the cero. The cero charged like a missile at them. Stark stood to counter with his own but Neliel stood in front of him, raising her left hand. The cero halted in its tracks as Neliel opened her mouth swallowing the cero and returned it mixed with her own pink cero. The cero doble engulfed mitsuomi in a huge explosion. The smoke dissipated and the scene shook some to their core, mitsuomi stood nearly unharmed with a black draconic wing protecting him, when it flapped back his skin was pure white and the white liquid had formed a partial mask on the left side of his face.

Mitsuomi vanished with a buzz of static and appeared behind aizen but he managed to dodge, "that was..sonido" stark thought. Aizen appeared above mitsuomi, "Bakudo #61 Rikujokoro" he recited as six rods of light trapped mitsuomi but he was not done, "Bakudo #63...Sajo Sabaku" he added as a yellow chain wrapped around mitsuomi's struggling form. Mitsuomi hissed and snarled trying to free himself but his reiatsu surged cracking the kido, "his reiatsu..is completely like a hollow now..nearly a vasto lorde level...interesting" aizen thought and performed a handsign, "Bakudo #99 Kin" he recited. Mitsuomi howled as black fabric wrapped around his arms and body in the shape of an X. The remaining espada stared at the struggling mitsuomi, "what now Lord Aizen?" asked stark.

"Its seems...I have found a new arrancar to replace the one we lost" aizen replies. Aizen reaches in his coat and pulled out a small box containing a small orb, "are you sure my lord...what if he rebels?" asked Zommari.

"He won't...if it comes to it...he'll chose to serve me for the chance to kill me someday" aizen replies. Aizen approaches mitsuomi and opens the box the orb glows as tendrils attached to mitsuomi's body, "now...become my greatest tool" he states.

*Mitsuomi's Inner World*

Mitsuomi staggers through his castle as his body convoles, "God..uhh..Oh..No..." he howls, as his body leaks white fluid. Zetsuei appears but can only watch, "Mitsuomi..the two of you are merging...Aizen he..he killed you and the only way to save you..." she states.

"Was for us to merge...you're becoming a hollow...Now Aizen wants to turn you into an arrancar" his hollow states. The hollow appears as his body is cracking, "I can't save you now..mitsuomi..don't let him use you" zetsuei states, as she starts to vanish. Mitsuomi reaches out but his arm cracks away, "Zetsuei Don't leave me" he cries.

"Please find me" zetsuei states, as her body vanishes. The world around him cracks and splinters as his world merges with his hollow but mitsuomi rears up letting out a horrific wail as his world crumbles.

(song playing...Hyouhaku..naruto shippuden ost)

Aizen and his espada watch in awe as the smoke billows around mitsuomi, "show us your new form" aizen thought. The smoke cleared revealing mitsuomi on his hands and knees, his skin was still white but his black hair now had a streak of white in it, "Rise my new Arrancar" aizen states. Mitsuomi slowly rises as the others taking in his features, his arms now match with black fingers and strange tribal like tattoos on both pure white arms, his chest is mired with several battle scars and his hollow hole on the right side but the left side of his face was obstructed by his long hair. The wind blew the hair away revealing his mask fragment. Which was similar to before but now the partial mask contoured and sunk into his face on the left, stopping above his mouth and his left ear with a purple lightning mark. The thing that stood out for some was the two different colored eyes, one hauntingly steel blue and the other black with a gold iris. Aizen turned to his espada, "My Espada..welcome your newest brother...Mitsuomi Kiriyu...The Zero Espada...no longer will the espada be one through ten but zero through nine" he explains, as the others gasp in shock. Aizen approaches mitsuomi placing a hand on his shoulder but mitsuomi grabs the hand, "I may be one of your men now but..Sosuke...Mark my words..you will regret this decision" mitsuomi utters, passing him and vanishing with a buzz of sonido. Aizen fixes his coat as gin appears, "hope ya did the right thing...should someone go after him?" he asks.

"No...let do him as he pleases...Mitsuomi will serve me" aizen replies, vanishing. Gin watches as the other espada return to their wings, "Capt Aizen...I wonder...did you create your greatest ally or your worst enemy" he thought, vanishing.
