'Kurosaki Ichigo/Aizen Sousuke'

"Kurosaki Ichigo/Aizen Sousuke"

Xtra Chapter

Aizen looked on in smug satisfaction at the work of his Arrancars even if there were only four Espadas remaining those being Starrk, Ulquiorra, Akiyo and Grimmjow. He was impressed that Grimmjow was still alive despite Nnoitora, who was stronger than him died. On top of that Ulquiorra revealed his Segunda Etapa, the next stage of Resurreccion further proven true by Akiyo who had defeated his foe without resorting to his own Segunda Etapa. He expected Tosen to die so it didn't matter to him. The only ones remaining of his army was him, Gin and the four Espadas.

He had to say that he was impressed at the might of the Gotei even if the exiled captains the so-called Visoreds had appeared announcing that they only had a common enemy with the Gotei that being him. He forbid his Espada from killing the shinigami, after all, he wanted them to be there during his ascension. Somewhere during the fight three more former captains appeared. Kurosaki Isshin formerly Shiba, Kisuke Urahara and Yoruichi Shihoin. Too bad they only helped him in his evolution.

He glanced at the fallen unconscious shinigami once more before turning around and walking. "Gin, open the senkaimon will you." Said person opened the senkaimon and stepped aside letting Aizen and his Espada enter.

Due to his departure Aizen missed Isshin, Kisuke and Yoruichi sitting up.

"Well...what to do now Kisuke?" Yoruichi asked.

"Isn't it obvious Yoruichi-san? We'll have to trust in them waiting on the other side."

"Anyway, I'm leaving. I'll be with the twins and Orihime. You coming?"

"Sure why not?"

"Did you tell them what happened here?"

"Yes I did Yoruichi-san. Knowing him, he'll probably take all of them down by himself."

"She'll be pissed though..."

"Nah I know my son. He'll let them have some of the fun."

Stepping out of the senkaimon Aizen and his cohorts were greeted by the sight of a silent Karakura town.

"Looks like everyone is asleep." Aizen said as he looked across the town. "Well my dear Espada and Gin, you may rest now leaving the rest to me." Receiving nods, he turned around and started walking only to be stopped by an unknown voice right beside him.

"How rude. Ignoring me even though I'm right beside you."

Aizen leapt to the side and took in the appearance of the unknown individual. The man was tall, lean and muscular with orange hair and a variation of shinigami garb along with a variation of a captain's haori with the number...Zero? And orange hair... "Kurosaki Ichigo?" Aizen asked with wide eyes. From the corner of his eyes he saw the Espada and Gin tense and ready to take on the unknown enemy.

Ichigo smiled and chirped. "Oh my! Looks like you do know me!"

"Of course I would. I do have a hand in your creation after all." Aizen replied smiling but on the inside he was wondering why he couldn't feel anything from the orangette.

"Lord Aizen." Ulquiorra called out still in his Segunda Etapa. "Who is this?"

"Who cares?! I'll take him down!" Grimmjow yelled before lounging at Ichigo who simply pulled out his sealed zanpakuto and held it by his side. "Die!" Just as he was about to hit Ichigo, to everyone's surprise he fell apart in two passing by Ichigo's sides while he smiled on.

'What the-?'

"My my aren't you the rude one?" Ichigo chided looking down at Grimmjow.

'When did he cut him?!' Everyone thought with wide eyes.

"Kurosaki Ichigo." Aizen called out getting his attention. "I see you've become a Squad Zero officer. Congratulations is in order I suppose."

"Thanks! But don't think that I'll be going easy on you."

"Hmph. We'll see about that." Aizen said as he raised his hand and indicated the others to leave.

Akiyo nodded and opened a Garganta only for it to slam shut surprising him.

"Now where do you think you're going Espada-san?" Ichigo asked as he grabbed Akiyo by the shoulder.

Akiyo lashed out with his scale arm and successfully hit Ichigo only to recoil in pain.

"Now it'll be like this. I'll be facing Aizen, Gin and Starrk while Ulquiorra and you mister-whoever-you-are will be left to deal with..." Ichigo paused as the air shimmered before a large shadow covered them with four cloaked figures on the huge monster's shoulder. "...them."

Everyone's eyes widened when the figures removed their cloak revealing Tia Halibel and her fraccion.

"Dammit..." Stark cursed under his breath as he looked at her.

Aizen's eyes narrowed as Tia was wearing a short denim jeans, a black T-shirt under a white vest. On top of that, she wasn't wearing her mask. He suddenly gasped as he saw a long blade sticking out of him and looked over his shoulder to see Gin grinning at him. 'When did he-?!'

"Hahahaha! What's with this sudden plot twist?" Ichigo laughed.

"THIS ISN'T FUNNY!" The Espada yelled.

"Lord Aizen!" Ulquiorra said as he flapped his wings and lounged at Gin.

"Girls!" Ichigo snapped his fingers and Ulquiorra along with Akiyo was grabbed by Ayon who then ran off to a different direction with its masters in toe.

"Kill him, Kamishini no Yami." Aizen gasped as a hole opened up in the center of his chest where the Hogyoku was. Gin grabbed it and flashed away hiding his presence from everyone except Aizen and Ichigo.

"Dammit! Are you alright Lord Aizen?" Starrk asked as he held Aizen. He was surprised when the man started chuckling. His eyes widened when the hole sealed up leaving a small one where the Hogyoku was supposed to be.

"Thank you for your concern Starkk but do me a favor and keep Kurosaki Ichigo occupied while I'm gone to retrieve the Hogyoku." Aizen said before looking at Ichigo who seemed amused. This concerned him. Ichigo was amused instead of shocked at his regeneration as if he was... 'He's analyzing me.' He then asked Ichigo, "Surely you don't mind?" He was expecting Ichigo to stop him but was surprised by the answer.

"Sure! I'll entertain myself with the Primera." Ichigo replied waving his hands in a shooing motion.

Aizen narrowed his eyes as he saw Ichigo turn towards Starrk and hold his sword by his side. This concerned him. Even he knew that after the battle Starrk had, he'd be too exhausted to continue fighting someone who is stronger than him. But he shouldn't care. Starrk would simply be a necessary sacrifice to his plans. He nodded at Ichigo and left.

After Aizen was gone Ichigo sheathed his sword and sat down on the ground leaving a dumbstruck Starrk. He patted the ground beside him and said, "Don't worry. I'm not gonna fight you. You're too tired and lazy to fight again."

Starrk narrowed his eyes and observed Ichigo for a few moment before shrugging and sitting opposite to Ichigo. He didn't get out of his Resurreccion yet. After a few moments of observing he asked what's been on his mind since the orangette's arrival.

"Why is it that I can't sense anything from you?"

Ichigo smiled and said, "Because I exist on a separate dimension. Surely you heard what Aizen said didn't you?"

"How do you know what he said and what he didn't?"

Ichigo simply pulled out his phone and showed it to Starrk. "I have source."

Starrk nodded and frowned before asking, "Then what would you say about the captains? I was able to sense them but they were able to keep their pressure to the barest minimum not affecting anyone. How did they do it?"

"They're subconsciously controlling their reiatsu keeping it chained and releases only when necessary."

"I see."

A sudden flash of light and a mushroom smoke cloud caught their attention. Ichigo squinted his eyes and saw Tia fighting her successor, who by now was in his Segunda Etapa and was losing. On the other hand Ayon was struggling against Ulquiorra. Ichigo sighed and pointed his fingers in their direction as he saw Ayon falling backwards and Tia flying away from her successor. "Hado#99: Goryuutenmetsu."

Starrk's eyes widened when the ground started shaking and from afar five dragons of fire and ice erupted and attacked his comrades. He cursed when their reiatsu vanished.

"What was that?" Starrk asked Ichigo who seemed disappointed.

"Kido. A level 99 Hado." Ichigo answered and vanished.

With Aizen

"Beautiful." Aizen having gone through another transformation into a butterfly-man breathed out as he saw the dragons devour his third and fourth Espada while Rangiku cried over Gin's half dead form. He then turned in the couple's direction and raised his sword. Just as he was about to bring it down his hand stuck.

"Hey now, no need to deliver more pain to a dying person." Ichigo was grabbing his arm.

Rangiku gasped and whispered, "Head Captain Shiba."

Ichigo smiled over his shoulder and raised a hand in greeting. "Yo."

'Head Captain Shiba?' Aizen thought confused. In Gotei there's just...Captain...Commander...so he was the Head Captain of Squad Zero?! He smirked, proud that his creation kept on surprising him. Though one thing kept on bugging him. Why couldn't he sense him? 'Ah, pure raw physical power instead of reiatsu.' Right...?

"Well then Aizen, let's take this somewhere safe shall we?" Ichigo said to which he raised an eyebrow. If there was anything he won't tolerate then it would be ordering him around.

"What gives you the rig-mmh!" Before Aizen could finish Ichigo had grabbed him by the face and flew straight to the outskirts of Karakura passing over Starrk and then Tia and her fraccion. He nodded at her giving her the silent order to return. She nodded back and left but not before binding her successor, who had somehow survived the kido, in multiple bakudos. When he arrived at the right spot, he threw Aizen downwards sending him straight into the earth.

Aizen pulled himself out of the crater with a hand on his face. An expression of disbelief was seen on his face. 'What?' He didn't get it. How was a mere mortal able to manhandle him? 'Doesn't matter. He caught me off guard and now I'll show him true power.' He stood up with a smirk and said, "I applaud you for your success in catching me off guard."

"Why thank you! Let's get this over with shall we?" Ichigo replied pulling out his two sealed zanpakutos, amused that the man in front of him failed in getting a rise out of him, if the scowl was anything to go by. "Ignite and Disintegrate. Turn White and Solidify. Getsu no Ikari!" He was enveloped in a torrent of fire scorching the ground around him. When the fire died down, it revealed him holding his massive blades with fire running along the back side. "Neat, right?" Ichigo asked with a grin.

'A "Getsu" huh? Just like mine.' Aizen thought as he observed the blades with interest. "Well, allow me to show you the power of a transcendent being." He was still rattled by the fact that he still didn't feel anything coming from the orangette. 'Doesn't matter. He'll fall before me.' Right…? He spread his wings and let himself get enveloped by a bright flash of light failing to blind Ichigo.

Ichigo kept on glancing around searching for signs of the brunette's appearance. A flash of light behind him caught his eyes and he quickly raised his left blade blocking the strike. He grinned when he felt the raw power behind the strike as the mountain behind him was blown apart to pieces.. He quickly snapped his wrist and faster than Aizen could expect delivered several cuts on his body.

Aizen gritted his teeth as he touched the cuts that burnt more than Ryujin Jakka. Because of that his healing speed had decreased as well. Once the cuts closed up he looked at Ichigo who was grinning at him. He snarled and dashed swinging Kyoka Suigetsu at him. Again Ichigo blocked with his left blade and this time slashed him from shoulder down to his hip. He couldn't stop the pained sound leaving his throat as the gash this time burnt more than the cuts from before.

"Nenshou Getsuga!"

Aizen leapt out of the way of the fire that was aimed at him but even if he did dodge it, the heat of the flames hit him boiling his pristine white skin. He hissed and willed the Hogyoku to regenerate. At this rate he'll end up as 'Aizen Teriyaki'. He leapt back to dodge a slash that was aimed at his chest exactly where the Hogyoku was. The Hogyoku pulsed in protest from the heat radiating off of the blade.

"Neppa."

Aizen was surprised when nothing came at him but understood what it was a moment later as unbearable heat scorched his skin getting through his reiatsu armor. He fell to one knee as he gasped and panted for lost breath.

"You okay?" Aizen gritted his teeth when he heard Ichigo's mocking voice. "Y'know, I was expecting a bit challenge from you but in the end, even you failed to entertain me." Ichigo's voice sounded cold and bored.

Aizen stood up and slashed at Ichigo. "Hado#32: Oukasen!" A humongous yellow blast of lightning shot from his sword and headed towards Ichigo. He took this time to start incanting his favorite hado. As he saw Ichigo weave out of the way of the lighting blast, he pointed two of his fingers and roared, "Hado#90: Kuroshitsugi!" He smirked when he saw the huge black coffin trap Ichigo. He didn't dare let it down knowing that the longer he kept the more the person in it will be stabbed with spears. He was startled when the box lit up in fire and shattered spreading flames everywhere.

"That was a good Kuroshitsugi but weak nonetheless." Ichigo appeared a bit above him with his right blade raised high and the air around it shimmering in heat as the flames roared. "Be a good boy and sleep." With that he brought his flaming blade down on Aizen cutting a good chunk off of his body on the left side.

"AHHHHHHH!" Aizen roared in pain as a he lost a good chunk of his body which to his shock immediately disintegrated. Not even ash remained! He landed on the ground with a loud thud gasping and silently screaming in pain he never experienced before. He willed the Hogyoku to regenerate what he lost and got up on his right knee with his sword stabbed on the ground to bear his weight.

"I'm not surprised that you survived. Any normal person would've disintegrated the moment Getsu no Ikari came in contact the way she came down on you yet you just lost a chunk of your left side. It's impressive." Ichigo said from behind Aizen startling him. Ichigo scowled as Aizen teleported himself to another hill opposite to him.

Just as Ichigo was about to say something, a heavy weight pressed down on him widening his eyes as he dropped to his knees. He looked up and saw Aizen once again going through another transformation. The pressure increased when Aizen was enveloped in purple reiatsu and vanished to shower the hill in blood revealing Aizen in his new form.

"That sure surprised me!" Ichigo said as he stood up grinning. "Now you hollowfied?" Before he knew it he was being held by his neck by Aizen who was glaring at him through his blank eyes.

"Your time is over Kurosaki Ichigo. Thanks to you I've gone through another evolution. You're arrogance will cost you for not unleashing your bankai."

"Oh shush you." Ichigo said he slashed Aizen again sending the monster flying back a few meters. He scowled and said, "Even with this new form of yours you can't push me into using my bankai. Though I'll honor you with this." Reishi strings shot out of his body and a black hole opened up beside him. The reishi strings shot into the hole and pulled out a daito.

'A second zanpakuto?!'

Using the reishi strings, he held the three blades perpendicular to the ground parallel to each other and said, "Obliterate, Zangetsu."

Heavy weight pressed down on Aizen as he observed Ichigo getting engulfed in reiatsu and soon a solid white sphere formed with Ichigo in it. He stood up from the ground with baited breath as the sphere started cracking before shattering to reveal a humanoid lizard holding now a pair of same but white blades with blue flames licking the backside.

"Let's get this over with shall we?" Ichigo asked as he let out a visible puff of breath snapping Aizen out of his stupor. With a boom, Ichigo appeared beside Aizen, both blades reared back.

Quickly Aizen swung his sword vertically and blocked the dual blades but didn't take in the account of the force behind the swing, so he was sent flying backwards. Using the skulls on his wings he created six ceros and launched them hoping to deal some damage to Ichigo. What he didn't expect was for Ichigo to coat both blades with reiatsu before forming a crimson cero in front of teeth before absorbing it in both of his blades.

"Fragor!"

"Getsuga Cero!"

Twin crimson waves of energy clashed with six purple death beams canceling each other out. The explosion caused by the cancellation created a massive mushroom cloud and sent sonic waves hitting both Ichigo and Aizen.

"Y-You…! You're a monster!" Aizen snarled and Ichigo snorted.

"Speak for yourself." With that both of them clashed again and again sending waves that reshaped the landscape. Both of them appeared several meters away from each other with Aizen healing at a very slow pace while Ichigo's own cuts healed in mere seconds. Ichigo then pointed his blades and to Aizen's horror said, "Hado#99: Goryuutenmetsu." The whole place shook and five skeletal flaming dragons shot out from the ground before launching themselves at Aizen who was too shocked to dodge and hit him straight and square. And another explosion occurred. Ichigo swung his blade and dispersed the dust around him. Hearing a thud, he sonidoed to the place and saw a fully scorched Aizen lying face down on the ground with two broken pieces of Hogyoku that slowly turned to dust. Ichigo sighed and resealed his zanpakuto coming out of his transformation and flipped Aizen on to his back.

To his surprise Aizen regenerated and healed up to his normal human self within mere seconds and rose to his knees hacking.

"W-What the?" Aizen said as he looked around and snarled when his eyes landed on Ichigo. "You failed Kurosaki Ichigo! You failed to kill me!"

"Actually I didn't." Ichigo said pointing behind Aizen. Aizen looked back and paled as the Gates of Hell opened up and a Kushanada stabbed him before dragging him away for eternal punishment.

"Happy Journeys!" Ichigo said waving at Aizen.

"Curse you Kurosaki Ichigo!" With that the doors slammed shut and disappeared.

Galaxy-like eyes snapped open and roamed around the room their owner was at. Figuring that the place was his own chambers, the figure sighed and thought, 'This dream again?'
