Naruto the Oldest Soul

Disclaimer: I do not own Naruto or Bleach. Naruto is owned by Masashi Kishimoto and Percy Jackson is owned by Tite Kudo respectively. Certain elements were inspired by various Naruto/Bleach crossover fanfictions.

AN1: I KNOW another story! I just can't help out! Been watching A LOT of Bleach! I know the manga ended awhile ago and the anime never did the last arc but I still really enjoyed it! In this story WILL be OP as fuck!

This will probably be a harem (it is just more of my style)

Chapter 1 Aizen's Escape does not go as planned.

Ichigo Kurosaki a human with Shinigami powers lay broken unable to move alongside fukutaichō of Squad 6 Renji Abari. They were both grievously injured trying to stop Rogue Taicho Sosuke Aizen. Even Sajin Komamura Taicho of squad 7 was grievously injured after being hit by Aizen's Hado 90 Kurohitsugi without incantation. Ichigos human friends Uryu, Orihime and Chad along with Ganju Shiba were helplessly on the sidelines unbale to do anything.

Aizen was carrying Rukia Kuchiki who had narrowly avoided her own execution only to learn it was planned by Aizen to get something inside of her she did not know existed. Kisuke Urahara's Hogyoku.

"Now that explanations are finished let us continue my dear Rukia." Aizen said pleasantly as he plunged his arm into Rukia's chest. Only his arm was not in its normal form but green and organic.

"Uh." Rukia groaned as she was unable to move or resist due to Aizen Reiatsu making her powerless state little more than a doll.

"Rukia!" Ichigo yelled trying to get up but his injuries prevented him from even getting off the ground.

"No." Renji said in despair while Gin Ichimaru just smiled creepily watching his fellow conspirator get his long sought out prize.

Aizen smiled as he pulled his hand out with a small blue orb in hand while a hole remained inside Rukia. He held onto Rukia with his left hand as his right hand held onto the Hogyoku with reverence. "Incredible. So little yet so much power." Aizen said in wonderment as the hole closed up in Rukia's chest after his hand was removed. "Huh. Kisuke Urahara was quite an inventor. Even after the object is removed the soul itself is left intact and unharmed." Aizen mused as Rukia blinked once she realized she was not dead or injured.

Before anyone could celebrate Aizen turned to Gin and said coolly "Rukia is no longer any more useful to me. Dispose of her." Hearing these words Ichigo and Renji struggled to get up to no avail as Aizen lifted up Rukia as an easy target.

"Very well Aizen-Taicho." Gin said with a mock bow as he pointed his short sword in the direction of Rukia "Shoot to kill Shinso." Gin said as he thrust his sword in Shikai state.

Rukia closed her eye thinking this was the end ignoring her friends cries of desperation but only felt herself being carried in someone else's arms. "Rukia are you alright?" a familiar voice asked her as she jolted her eyes in surprise.

"Nii-Sama!" Rukia shouted in despair but seeing his injuries made her fear for the worst. "Did you get hit for me?" Rukia asked with tears beginning to form.

"No. Even before I came to save you it almost seemed like the blade get diverted ever so slightly off course." Byakuya admitted as she widened her eyes in surprise.

"Gin. Did you get careless? If not Rukia I expected you to at least pierce Kuchiki-Taicho." Aizen said in disappointment.

"Sorry Aizen-Taicho. Somehow something or someone actually managed to redirect my Shinso right before I could hit my target." Gin said with shock. Before anyone could respond Gin hunched over in pain as he split out blood. "Blugh." Gin gurgled as he collapsed on his knees.

"What is this? Somebody hit Gin so fast his ribs broke upon impact." Aizen said in surprise as he narrowed his eyes as he and Kaname Tosen were on guard.

"Sōkatsui" a voice above said as a massive blue fire ball tried to crash into Sōkyoku Hill.

"Bakudo Number 81: Danku." Aizen chanted as a large semi clear wall appeared above him blocking the Sōkatsui from hitting him. Despite the wall protecting them from the blast, the explosion from the Hado spell dwarfed the Hill as everyone covered their eyes from the smoke.

"Impossible. Even with my Bakudo reducing the power of that blast a level 33 Hado Spell did this kind of damage without an incantation?" Aizen said in surprise as he looked at Ichigo and his friends only to see them surrounded by a green barrier. Even Ichigo's human friends were now with Ichigo and Renji behind the barrier.

"How did we get here?" Orihime asked in confusion as she did not remember moving let alone being behind Ichigo.

"Who did all this?" Ichigo shouted as he attempted to look around.

"I did, Ichigo Kurosaki." A cheerful voice said from above. Everyone looked up only to see a blonde man who looked in his 20's. He was reasonable tall with blue eyes, odd whiskers on his face and a grin as he looked mischievously at the people beneath him. Unlike all the Shinigami in the Soul Society this man was wearing casual clothing from the world of the living. He wore a red shirt and orange shorts that had a belt for his sword along with blue sandals.

The mystery man just slowly descended as the rouge Captains were on guard while Ichigo and his friends just looked at him at awe. "My name is Naruto Uzumaki! Nice to meet everyone!" Naruto said brightly as everyone looked blankly at his cheerful attitude. Naruto was on the ground as he sent a grin to Ichigo and his friend with his back turned to the traitors.

"You are a threat to Aizen-sama! Die!" Tosen yelled as he used Shunpo and tried to slash the new stranger head off.

Ichigo and the others tried to give a warning to the blonde man but the next instant he was gone and Tosen was face first into the ground while Naruto was standing causally next to Aizen who turned in surprise. He had his hand on the hilt of his Zanpakou ready to use it.

"Looks like the Calvary has arrived." Naruto remarked as he leapt back before 2 blurs arrived to subdue Aizen. Yoruichi Shihōin had managed to grab his sword hilt to prevent Aizen from drawing his Zanpaktou while Soifon had her sword aimed at his neck. Yoruichi was rather beautiful, slender and busty dark-skinned woman. She had golden eyes, and purple hair that she kept in a ponytail. Her attire consisted of a black, backless, sleeveless undershirt, an orange over-shirt with two white straps on each shoulder, a large beige sash around her waist and black stretch pants with a pair of lightweight brown shoes. Sui Feng on the other hand was a more petite shorter woman. She had dark hair and gray eyes and the standard Shinigami captain's uniform, Soifon wears the uniform of the commander-in-chief of the Onmitsukidō, which has no sleeves and doesn't cover the back.

"Well hello to a familiar face from 100 years ago." Aizen causally remarked as he met Yoruichi hate filled eyes with a calm face.

Several swishes were heard as nearly every Taicho and fukutaichō of the Gotei 13 had arrived on the hill.

"Everyone!" Ichigo said in shock and glee as the barrier around him and his friends has dissolved.

Fukutaichō Shuhei Hisagi had his blade pointed at his former Taicho Kaname who was still face planted into the ground. While several Shinigami had their blades at Gin who stood shakily still holding his stomach.

"Sorry Aizen-Taicho it looks like I got caught." Gin said with a grimace as his ribs were still busted.

"Its alright. No need to worry Gin. Hello Soutaicho Yamato." Aizen greeted politely not the least concerned with the angry glare of the powerful Taicho.

Naruto had deactivated his own barrier once the Gotei 13 had arrived but as soon as he landed, he felt a hand grab his wrist and a sword against his throat. He distinctly smelt the scent of female perfume.

"Sorry handsome but you are not going anywhere." A feminine voce said both playfully and seriously at the same time. Naruto tilted his head so he could look at his captor and he admitted to being a bit awestruck. The woman was fairly tall although not quite as tall as him only reaching his shoulders but in sheer beauty and good looks may have easily been one of if not most beautiful Shinigami he had met. She had had wavy strawberry blonde hair that reached all the way to her lower back along with light blue eyes that sparkled with amusement and seriousness. She had a very pretty face with a beauty mark just below the right part of her lower lip. She wore the typical Shinigami black uniform with pink over her shoulders. Easily the most notable part about this woman was her very large breasts that were easily one of the largest pairs he had seen with her more than ample bosom shown with her robes loosened.

"May I at least know the name of my pretty captor?" Naruto asked with a charming smile as he looked back at the smirking woman.

"I suppose I can share my name with a cutie like you." The woman said with a wink. "I am Rangiku Matsumoto, Fukutaichō of squad 10." Rangiku told him as she looked curiously at the very handsome man.

"Well Rangiku-chan." Naruto said as Rangiku smiled widely at the familiar honorific. "I am Naruto Uzumaki." Naruto told her as she got an idea.

"Well Naruto-kun." Rangiku said putting great emphasis on the honorific as Naruto grinned. "Mind telling me what you are doing here in the Soul Society?" Rangiku asked batting her eyelashes as Naruto rolled his eyes playfully.

While this interrogation was going on everyone looked flatly at the busty Fukutaichō and unknown blonde which appeared to be more flirting than anything else.

"That is enough! Intruder tell me your name and purpose!" Yamato demanded as he unsheathed his sword making all the other Shinigami a little on edge.

"Aw! Did you forget me already? I mean it has only been about 2000 years or so since I have stopped visiting." Naruto whined as Yamato eyes widened.

"It can't be! You?! You just up and left without a word all this time!" Yamato said angrily with Shunsui and Ukitake hearing some heartache as well.

Naruto actually looked away abit ashamed before Yamato sighed and ordered "Fukutaichō Matsumato. Release him at once."

Rangiku blinked before she let Naruto go but not before leaning over so he could get a nice look at her girls with Naruto showing his appreciation with a wide smirk.

"Well this has certainly interesting but we must be going now." Aizen announced calmly as every Shinigami glared at the traitors.

"It doesn't look like you are in any position to make idle claims Aizen." Yoruichi said with a growl before Aizen smirked.

"This sensation…." Naruto said as he widened his eyes. "Get them out of there! Its Negación!" Naruto yelled to Yamato who widened his eyes as well.

Without a moment of hesitation, he yelled "Get away from the traitors!". The Shinigami around Gin scrambled, Shuhei leapt back and Yoruichi, and Soifon leapt back just as a yellow beam of light enveloped each traitor. The light caused the traitor and a small piece of ground they were standing on to levitate into the crack in the sky.

Several Taichos and Fukutaichōs were prepared to released their Zanpaktous in an attempt to stop the former Shinigami Captains from leaving.

"Stop! It is too late." Yamato said gravelly.

"Soutaicho why?" Shuhei asked in despair seeing his captain leave as a traitor,

"That light is called Negación and it is used by hollows to rescue their own. Once the light hits a target the target and outside world are in completely different worlds. It was over once that light hit them." Yamato said gravelly having re sheathed his sword.

Sure, enough in the crack in the sky were several Gillian class Menos Grande Hollows all screaming.

"Look at all those Gillians." Rukia said in shock.

"Wait there is something else there too!" Orihime shouted as she pointed at a very large purple eye behind the Gillians as the Negación carried the traitor captains closer and closer to the sky every second.

"Tosen!" Komamura shouted standing up despite his injuries. "Get back here!" He demanded as Tosen had stood up with notable trouble.

"…." Tosen had refused to say anything to his former friend.

"Where is your sense of Justice?! Was it not to avenge your dead friend?!" Komamura asked outraged to Tosen as he hovered away.

"I seek the path of least bloodshed. That is the path of justice and I walk the path of Justice." Tosen explained coolly.

Jushiro Ukitake stared up at the ascending Aizen and said in disbelief "So you joined with the Menos and Hallows. Why are you doing this?"

"I need to continue to climb higher and higher." Aizen claimed with notable disdain.

"Have you become that corrupt?" Ukitake said with a glare.

"How arrogant. Neither you or I or even the Gods have sat on the top before. I however shall stand above all the rest." Aizen revealed as he pulled off his glasses and sleeked his hair up. This showed a much less kind Aizen as he neared the opening in the sky.

"Ryoka boy." Aizen said addressing Ichigo who struggled to get off the ground. "It has been interesting." Aizen remarked before staring at Naruto with curiosity. "I believe you are something different I have not seen before." Aizen remarked calmly.

"Like I would let you get away that easily." Naruto growled back as he lifted his hand up.

"Idiot boy! The Soutaicho was clear that they are in another dimension now!" Soifon yelled in frustration.

Naruto stayed quiet before a golden ball appeared in his hand. In a next instant it transformed to become something like a shuriken with the ball in the center. It gave off a screeching bell like sound.

"What is this?!" Ukitake asked in shock and amazement.

"Amazing! Whatever that ball of energy is it feels different from Reishi but somehow even more powerful." Rukia said to Renji who nodded dumbly.

Naruto threw it and it went in the middle of where the 3 beams are.

"Fool. No matter what do it cannot reach us now." Aizen said confidently before his eyes widened as the Shuriken expanded hitting all 3 lights at the same time.

"Impossible! He is breaching the Negación?!" Aizen shouted with some fear as cracks appeared on the barrier.

Just as the barrier was about to shatter Aizen and his co conspirators managed to reach into the sky and disappear from the Soul Society.

The leftover enegery from the Shuriken exploded as everyone shielded their faces from the explosion despite it being high above their heads. The explosion of wind and dust seemed to eclipse the sky itself before finally disappearing.

"So powerful. Not even a Bankai can damage the Negación yet that one attack nearly destroyed them." Byakuya commented as he held Rukia shielding her with his own body despite his injuries.

As the Gotei 13 settled and looked at Naruto with shock and fear Naruto only sighed. "It seems I was just too late. Oh well it just means that war is coming." Naruto said in disappointment.

The only one not shocked at his display of action was Yamato himself who to the shock of everyone there actually chuckled. "Any doubts I had it was really you just vanished. Naruto-sensei." Yamato revealed as everyone at the hill took a moment of silence.

"SENSEI?!" Everyone yelled at the same time as Naruto who had landed looked up.

"Oh yeah." Naruto said simply as eh shrugged his shoulders.

"That guy over there is the Soutaicho sensei?" Rukia stuttered as she explained how the Soutaicho was over 2000 years old to her shocked human friends.

"Sheesh you leave for a few thousand years and suddenly nobody knows who you are." Naruto complained with a whine as Yamato demanded everyone prepare for healing.

AN2: Hiya! Another story! Like my other stories this is essentially a 'pilot' chapter to test the water. I don't know fi I will use the Japanese for all consistency or use English versions of terms.
