"Yamamoto-sama, a large group of shinigami were attacked by several A to S-class hollows that somehow managed to breach Rukongai," yelled a shinigami in a panic.

"Send the Eleventh division to deal with the hollows and alert the Fourth division to gather the wounded," ordered Yamamoto with a heavy frown on his face.

"Hai Yamamoto-sama," bowed the shinigami before using shunpo to do as he was told as quickly as possible.

Twelfth Division

"Taicho, all of Soul Society has been put on emergency alert. Several high class hollows have somehow breached Rukongai," said Naruto as he entered his captain's lab.

"Hmm, is that why you came to visit me?" asked Kisuke with a knowing look in his eyes.

"No," replied Naruto as he stood across from his Captain. The two shinigami stared into each other's eyes without even flinching or blinking. Kisuke knew why Naruto had really come to visit him and Naruto knew his captain knew why he was here as well.

"So, will you be turning me in then?" said Kisuke with a raised eyebrow.

"There is no point in me doing that as they will eventually trace it back to you or Mayuri will turn you in as he will no doubt figure out what you did and gladly take this opportunity to clear his way to become captain. I did try to warn you that the gigai was not ready to be used yet, but you ignored my warning," responded Naruto calmly.

"Yes, I suppose you are right and you did warn me," conceded Kisuke with a small smile.

"You will have a few years before they learn of what you did. I would use that time wisely taicho," said Naruto as he turned to leave the room.

"Oh, congratulations on the little invention you created. I look forward to when it starts becoming mass produced for all shinigami," smiled Kisuke as Naruto used shunpo to disappear. The boy was definitely a prodigy and would do great things for the Twelfth division once he left and took it over as captain that is if Mayuri didn't kill him to get that position for himself.

Rukongai: District 70

Fourth division members ran all over the place as they treated not only the wounded shinigami, but also the wounded souls of district 70. Many of the homes and buildings were destroyed during the battle to get rid of the hollows that had somehow managed to get into Rukongai. No one found out how they did it, but they would worry about that later once everyone had been treated.

"Taicho, there are just too many people wounded and our units are running low on spiritual energy," panted Isane as she too was running low. Unohana quickly got up from her kneeled position as she had just finished healing a couple shinigami and there was a grim look in her eyes.

"I know, but we have to try our best and save as many people as we can. Just make sure that our forces don't push themselves to hard otherwise, they will be one of the wounded as well," sighed Unohana.

"Perhaps, I can be of assistance," said a familiar voice and both women turned around to see Naruto walking towards them.

"Naruto-san, what are you doing here?" asked Isane, before flushing as she realized she had addressed him so informally in front of her captain.

"I am curious as well," said Unohana with a raised eyebrow. Naruto stood in front of the women before reaching into his cloak and pulling out a small bag. They watched as he reached into the bag and pulled out a small spherical object that looked remarkably like a gigai.

"Eat this," said Naruto as he held it out for Isane to take.

"Why are you giving me a gigai?" asked Isane confused, as she took the item.

"Eat," repeated Naruto. Isane looked at her captain, received a nod so slowly put the object in her mouth, and ate it. A few moments after she finished swallowing it, her eyes widened in shock as she felt her spiritual power refilling rapidly.

"Incredible, my power is returning to me," gasped Isane in disbelief.

"They are called soldier pills, and will help restore the spiritual energy of any shinigami that eats it. There are side-effects though if it is taken continuously so don't give out more then two to each of your units," sad Naruto as he handed two bags to Unohana and started to take his leave.

"Wait, you are just going to leave?" yelled Isane, causing Naruto to paused and look back at both women.

"I have completed my mission to design something to increase the efficiency of the Fourth Division and decrease the amount of deaths. Should you need more then I will start working on more as they can be used for other divisions as well," replied Naruto.

"Thank you Naruto-kun, this new invention of yours will help more then you can imagine," smiled Unohana before surprising Isane by bowing respectfully to him. Naruto just nodded his head then used shunpo to return to his lab.

"Isane, I want you to distribute these soldier pills to all of our units right away. Make sure to warn them of overdosing," ordered Unohana with a hard look in her eyes.

"Hai," replied Isane then disappearing in a flash step.

'Naruto-kun, can you really feel nothing after creating something that can do so much good?' thought Unohana with a worried look in her eyes.

Gotei 13 Gathering: Two Days after Hollow Invasion

Naruto was standing before all thirteen Captains of the Gotei 13 with an emotionless look on his face. He had been called in here after Yamamoto had found out it was due to his new invention that many lives were saved. The council 46 had ordered he be brought in since he had allowed the release of an experimental new item without the proper authority.

The truth was that the Council 46 didn't like when something happened outside their control. They went through great lengths to put as many limitations on the Shinigami as they could so that nothing happened without their approval. Naruto had disrupted that balance when he delivered his new invention without any proper authority, which undermined their authority.

"Uzumaki Naruto, you have been called here today because you handed out an experimental invention without the proper authority. How do you plead?" said Yamamoto as he looked down at the man. Naruto was about to respond, but was interrupted when Unohana stood up and started to speak.

"Yamamoto-taicho, it was I who gave the order to distribute the items after seeing how helpful they could be in the current situation," interrupted Unohana, causing Yamamoto to face her.

"Are you taking responsibility for this action then?" asked Yamamoto sternly.

"Yes," replied Unohana without a shred of hesitation. All the other captains looked at her curiously, except for Zaraki who hadn't bothered to show up since he found the whole thing boring.

"Very well then," started Yamamoto, but stopped when Naruto interrupted him.

"Yamamoto-taicho, I take responsibility since I invented the soldier pills and taking any action against Unohana-taicho would severely hurt Soul Society," interrupted Naruto. He didn't really care what happened to Soul Society, but he did not wish to see Unohana get in trouble because the Council 46 felt threatened of his growing power.

Unohana looked down at him in slight surprise because she didn't expect him to come to her defense like he did. She knew they were close, but it was still surprising as he had never acted so protective of her before.

"Explain," replied Yamamoto.

"Since she became captain of the Fourth division, the efficiency and strength of its units have increased by 60 and has saved countless lives, shinigami and pulse souls alike. Those that are in the Fourth Division hold great respect for her and if she was to be demoted or any other type of action it would cause moral to go down in that division possibly leading to more deaths," explained Naruto, not in the least bit intimidated by all the eyes on him.

'He seems to really do care for Unohana-san, but I am sure I can break him of that by the time it comes to taking over Soul Society,' thought Aizen as he kept his face neutral.

"How do you know all this?" asked Ukitake curiously.

"I have done extensive research on the history of Soul Society and its divisions. Everything I have told you is the truth and if need me to, I can prove it," replied Naruto as he glanced at the division thirteenth's captain.

Yamamoto frowned at this because he didn't like what the boy was implying. Naruto was essentially saying that Unohana was untouchable unless he wanted the Fourth Division to go on riot because of their loyalty to their captain. The old man didn't doubt that they would do it either because Unohana was loved by those in her division and she was one of the few that actually had a zanpakuto that could heal. It seems he would have to let the boy off with a light reprimand or Unohana would insist she take the blame and that would be bad for Soul Society if he punished her.

"I agree with him Yamamoto-taicho. Punishing Unohana-san or Uzumaki-san for saving many lives seems to be a little extreme," said Aizen as he flashed a friendly smile at Naruto.

"If it makes you feel better, I tested his soldier pills, and they are perfectly safe so long as you don't constantly use them, otherwise you will gain an addiction that will limit your functions without them," smiled Kisuke as he offered his two cents.

"Hell, those damn pills could put an average shinigami on par with a high class hollow since it replenishes their reserves and allows a shinigami to fight for a longer amount of time," grinned Yoruichi.

"Very well, I will speak with the Council 46, but next time you will not get off so easy," said Yamamoto before dismissing everyone.

Naruto was making his way back to the Twelfth division quarters when a familiar presence appeared besides him. He turned his head to see Unohana giving him a beautiful smile.

"Thank you," smiled Unohana as she walked next to him.

"Why are you thanking me?" asked Naruto confused.

"I am thanking you for those kind words you said about me. I am happy to know that you care about me," smiled Unohana.

"I was merely stating a fact," replied Naruto, but Unohana could see it in his eyes that it was something more.

"Was that all or was it something else?" asked Unohana as she stopped walking, which caused Naruto to stop and turn to face her. Naruto didn't say anything, but he didn't have to because the look in his eyes told Unohana everything.

"Either way, I am grateful for what you did," smiled Unohana before taking a few steps towards him. Naruto didn't move an inch as Unohana came within his personal space then stood up on her toes and gave him a light kiss on the cheek.

"Have a good Naruto-kun," said Unohana with a beautiful smile before walking away. She didn't know when or how it happened, but she had developed deep feelings for the younger shinigami.

Naruto watched her go with a contemplative look in his eyes as he touched the spot she had kissed lightly. He just watched her disappear before using shunpo to take him back to his lab.

Break

"What are you still doing here? You should be long gone by now," frowned Yoruichi as she jumped down into the large under cavern and landed lightly on her feet.

This place was built by Kisuke so that they would have a place to train without anyone knowing what they were doing. In fact, Kisuke had even used this place to obtain his Bankai using that weird invention of his. Right now, he was sitting on a medium size rock with a smile on his face and a bottle of sake next to him.

"Hmm, just thinking about a few things," shrugged Kisuke, causing Yoruichi to scowl at him before swiping the bottle of sake and taking a swig.

"Still the same lazy bastard as always," grinned Yoruichi.

"Hehe, what can I say, it would be incredible tiresome to be on the run all the time if I chose to leave without warning," smiled Kisuke. He wasn't worried because he still had a year or two before they found out the truth behind his gigai and he wasn't going to worry about it until then.

"Yeah, well it is better then being executed," countered Yoruichi.

"Maybe, but I was hoping for something more along the terms of exile. I am sure if I tried I could convince them to merely banish me and avoid execution," smiled Kisuke with a knowing look in his eyes.

"Meh, getting away from this place wouldn't be so bad as it is becoming boring as hell. I bet there are a ton of things I could do in the Human world," laughed Yoruichi.

"Oh? What about that cute little Fuku-taicho of yours?" asked Kisuke with a raised eyebrow.

"She'll never grow strong if she continues to stay in my shadow and follow my every action. It'll best for her when I leave because she will finally be able to grow on her own," replied Yoruichi.

"Hmm, well in that case, we best enjoy the time we have left here while we can," smiled Kisuke as he pulled out another bottle of sake much to Yoruichi's amusement.

Human World

"Damn it, is he still pursuing me?" growled Hiyori as she leapt from building to building with incredible ease. She was a tiny girl with blond hair that were tied in pigtails and wore a red jogging suit that was decorated with the kanji of her first name.

Not too long ago she was the fuku-taicho of the 12th division, but ever since Urahara had become captain, she hadn't much to do with the division. She held a great deal respect for the last captain and thus refused to accept Urahara as her superior. It wasn't until recently that she decided to leave Soul Society when she started to exhibit some hollow like symptoms and knew what would happened if that was to get leaked to Yamamoto-taicho. Therefore, she had decided to run away when given the opportunity.

What she didn't expect was to be followed by the third seat of her division who had somehow found out about her new behavior. She normally would have taken great pleasure in fighting him, but with no control over her new power, knew she would be easily overpowered. Of course, she would never admit to it being the fact that the third seat who was following her really creeped her out and could probably easily take her out even if she wasn't bothered by her new powers. Nope, she would never admit to that. Too bad, she didn't get to think further on the matter a dark portal opened up in front of her and out walked the man who had been following her for the past ten minutes.

"Bastard, don't you got anything better to do then follow me?" growled Hiyori as she gripped the handle of her sword. She hid her fear well as she was really wondering how he was able to create a portal that quickly and get in front of her. From the power coming off the portal she could easily tell it wasn't the same that all shinigami used to open with their zanpakuto. No, it was something completely different and that worried her because she wondered what else he could.

"Hmm, your power is different then before Hiyori-fuku-taicho," said Naruto as he stood in front of the older girl, though she looked to be much younger then him.

"Cut that fuku-taicho crap as I have cut my ties with Soul Society," demanded Hiyori as she drew her zanpakuto.

"If that is what you wish, but I can not let you escape. I have many questions about your newfound powers and I will get the answers to them even if I have to kill you," replied Naruto as his zanpakuto disappeared and he formed to red beams in each hand to show he had released his shikai.

"Hmph, as if I will let some third seat punk take me out," scowled Hiyori, but before she could release her own zanpakuto she felt a shift in the air behind her and screamed in pain as a blade cut through her back. She managed to move enough away to avoid it going too deep, but was still bleeding profusely as she turned to glare at Naruto.

"My skills are far greater then yours. Surrender," stated Naruto calmly while he discreetly started to gather his spiritual power unnoticed by his former lieutenant.

"We will see who is stronger you bastard," yelled Hiyori in anger as she released her zanpakuto, but her eyes widened in horror as four black walls surrounded her.

"Destructive Art #90: Black Coffin," said Naruto before a loud screamed erupted from inside. It was a kido spell that had been taught to him by Aizen-taicho and its power was incredible, but Naruto hadn't used it at full power, which could be seen as the wall disappeared and Hiyori stood there with a glazed look in her eyes. A second later, numerous cuts appeared all over her body and blood spewed everywhere as she fell face first to the ground lifelessly. She wasn't dead, but she wouldn't be moving for quite some time.

"Hn, I expected more," mumbled Naruto as he walked towards his fallen lieutenant, but stopped when a man with short blond hair appeared in front of him.

"Sorry, but she is coming with me," said the man as he gazed into Naruto's eyes without flinching.

'His power, it is similar to Hiyori's, but more potent and refined,' thought Naruto as his eyes narrowed. He was about to capture this new threat as well, but felt several more people heading towards this area that all carried similar signatures to this man's own. This caused him to dispel his shikai and take a step backwards as he knew he couldn't take them all on, not yet at least.

"I have a feeling we will meet again," smiled the man before picking up Hiyori and using shunpo to disappear.

Naruto waited until he couldn't sense any more signatures before reaching into his uniform and tossing a few pills on the ground. The pills exploded causing hundreds of tiny bugs appear and they then started to ingest all the blood that was spilt on the roof of the building. These bugs were specially designed to ingest chemicals along with other liquid materials and keep them perfectly preserved until Naruto was ready to extract them. He may not have captured the girl, but he could still learn many things from her blood and perhaps design a way to alert him when others like her appeared in certain areas.

'Perhaps Aizen-taicho knows something about this beings,' thought Naruto before raising his hand and a portal of darkness appeared, which closed behind him as he headed back to Soul Society.
