Disclaimer: I don't own Naruto

Chapter 1

As the days passed after the end of the Fourth Shinobi War, Hinata Hyuuga seemed to have gotten a new drive and purpose. She was already approaching her thirties while looking as regal and fresh as a teen in their twenties. Whatever had happened during the last moments with Naruto Uzumaki, her crush and love interest from an age of six years old had made the previous shy and timid Hinata into a fearsome and dangerous person. The betrayal of Sasuke Uchiha, again, had managed to claim the life of her crush and she had brutally slaughtered him in front of the entire shinobi forces. His pleas for mercy had made even the most battle hardy and ruthless people flinch as she used the training under the Godaime Hokage and World's Greatest Female Medic to personally shatter every bone and tear apart most of his muscles as she destroyed his Sharingan, while keeping him alive and allowing him to die only after she destroyed his genitals with a chakra enhanced strike that caused them to blow like an explosive tag.

Sasuke had entered the camp under the pretence of surrendering. When he was alone he had managed to attack Naruto from behind and used Reverse Summoning to send Tsunade Senju and Naruto to Madara. Hinata had managed to disable two of the arrays but Naruto had been already taken and his Bijju extracted. The Toads had managed to once again Reverse Summon him but the damage had been done. Naruto had died the next day using the same jutsu both the Sandaime and Yondaime had used, the Shiki Fuiin while sealing the incomplete Ten Tails. He had died with a smile on his face while lamenting to Hinata that he was unable to marry her and keep his promise to her. Naruto had managed to transfer his entire chakra into her giving her nearly three tails of chakra due to his vast reserves making her an Uzumaki in terms of Chakra. For Hinata that was as good as marriage.

That day the second Aka No Shi (Crimson Death) was born where she had bathed in the blood of her enemies including traitors and Zetsu Clones. Her entire youthful frame was crimson red with the blood she shed and even though she had not gotten to kill Madara or fight him, she had gotten both Kabuto and Orochimaru in a two on one fight where she had secretly managed to knock them out and sealed them using Fuinjutsu she had learned from her beloved Naruto and his customised fuin tags on making a person or a corpse to be kept in suspended animation in a separate dimension. To prevent people getting suspicious she had used their blood to create Blood Clones to simulate their dead bodies to the people.

Hinata now had only a single purpose, that was to go back in time and take what was denied to Naruto and in turn her. That was why she had taken both Orochimaru and Kabuto. She needed their knowledge and medical expertise. And for this purpose she was living. Her moniker from the war had scared the old coots on the Hyuuga Council, who remembered the dangerous Kushina Uzumaki and her prowess and they had decided in all their wisdom to challenge her authority over the clan and insult her devotion to Naruto's memory. She had simply slaughtered them all leaving only the moderate factions alive and her actions had caused her to gain notoriety in the entire Konoha as the Ice Maiden. No one had since that day questioned her devotion to Naruto's memory and even the Godaime Tsunade Senju had given her the title of Honourable Uzumaki, as she was one of the last relatives of Naruto but never told him that.

Hinata had over the period of last several years had commanded the use of Root Tunnels and Hideouts that were located deep underneath Konoha and even few of the labs of Orochimaru that had not been discovered till this day. She had broken both missing nin using torture and Fuinjutsu and then disposed them by drowning them into an Acid Bath. From Tsunade and Orochimaru she had learned about medical knowledge and poisons and their antidotes, while from Kabuto she had learned his self healing technique and his vast experiments including the improved Edo Tensei. Naruto had left her several scrolls that he had gotten from Sandaime and Jiraya on Fuuinjutsu and she had learned all of them and using them, removed the Caged Bird Seal and abolished it. She also managed to learn the Hirashin but the Yondaime had cleverly tied the formula activation to Uzumaki blood. He himself had been injected with both Senju and Uzumaki blood and hence able to use the much feared technique. She also crafted a new taijutsu style using Jyuuken and Chakra Scalpels and her chakra control was finer than Tsunade and Sakura Haruno, both renowned as best female medics which included Shizune Kato and herself.

Hinata had also tried to recreate the Chakra Chains that Kushina Uzumaki was famous for but she had failed to form more than three chains which were deadly when she was using Taijutsu. She had from raiding the Root Hideouts managed to learn several secrets about Konoha and about plans crafted by Danzo-Orochimaru Alliance which had resulted in the death of Saindaime Hokage and several other horrifying things that had been done by Root.

She knew that the jutsu she would use would only send back her memories and half of her chakra back to her younger self. She had to time it correctly so that no one would get suspicious and in a clan that could see chakra coils and tenketsu that was next to impossible. She then created several plans and backups in order to prevent herself from failing to save Naruto. She had vowed to make things right for her beloved and even though she had to raze Konoha to the ground she would do it. Her plans and preparations were complete including her affairs which were all sorted and now she had only to wait to visit him last time.

The Next Day

Hinata Hyuuga woke up at five, a habit she had ingrained in herself since the day she had been saved by Nauto from the bullies during her academy days so that she could go out early and stalk err.. observe her hero before coming back to her clan compound for breakfast. Her father had never questioned her about this habit of hers and she had learned many things about her crush. She had got up while looking the same beautiful deadly woman that Naruto had admitted her to be while dying and posed in front of the full length mirror in just her lacy undergarments and imagining Naruto being with her while he did several naughty things to her. She had gotten a clothing set from Naruto during the war that was lined with seals which was a marvel for several shinobi and kunoichi and even blocked Byakugan and Sharingan. Those clothes had saved her life many times in battles and she had after the War decoded those seals and applied on her most clothes.

She dressed herself while looking over her room leaving no traces of her experiments and presence. She hid her will under several Genjutsu and locking seals that would disperse when her experiment would end and she would no longer be in this world. She thanked Kurenai Yuhi for teaching her subterfuge and patience to deal with others.

Casting a single glance she wrapped herself in the cloak that Naruto gave her and she decided to go face the music. As she left her room and compound, she found several of her clansmen waiting for her at the gates. She sighed to herself softly while cursing mentally for forgetting that today most would come to visit the place where Naruto was buried on Konoha Grounds in the Hokage Crypts as a honour for saving the world from destruction. The procession moved and after half a day Hinata came back while muttering to herself about people wasting her time. She knew that both Tsunade and Shikamaru suspected her due her unexamined disappearances from the village and she took all the precautions she could take. That was why she knew that Shikamaru and her old team mate Kiba had to be neutralized for her experiment to work without interruption. Shino had already been out of the country with his wife on her insistence as a wedding gift to them after the war. Also the act had gotten her scrutiny to lessen from Tsunade but not Shikamaru. He was as clever as Danzo and more paranoid than him. He was known as the advisor to Hokage but in reality, he was the head of the ANBU Black Ops Division.

Walking to the gates of Training Ground 44, she found Shikamaru waiting for her as she had instructed him to meet her at the ceremony for Naruto's Memorial. She flared her Byakugan before coming into his view and found his hidden guard that included 4 ANBU. Sighing to herself, she released her Shadow Clones to dispatch them and focussed on what was going to be her biggest hurdle.

"Why have you called me here Hinata on such a troublesome day?" came his lazy voice where he was leaning against the locked gates.

"You don't have to act now Shikamaru, I know what have you been planning for me." spoke the cold voice of Hinata Hyuuga.

"So you admit to it huh... . Why confront me then? What are you doing Hinata and how would this end? I hope you have not been doing what is wrong." spoke Shikamaru while going alert and signalling his guards to get ready. His mind flashed through several scenarios but for once what Hinata had been doing had been eluded him completely. She was doing something dangerous and reckless that he knew from her obsession in Fuuinjutsu and Kinjutsus. Hinata had been known after the War ended as a scholar who craved for the knowledge just like Orochimaru. Wait a minute.. Orochimaru. She didn't.

Hinata chuckled a cold mirthless laugh that sent shivers up his spine and chilled him to the bone. She smirked at him like she knew what conclusion he had arrived at and he gathered Chakra for his techniques. If she truly was that serious then he knew he was not going to survive the day, no matter who helped him or came in her way. She was known as the Aka No Shi for a reason and he wished again that Naruto had not died by the traitorous fool Sasuke's hand that day. He swallowed at the look she levelled him with her Byakugan enhanced eyes and swallowed the fear that appeared due her monstrous Killing Intent (KI) washing over him. His guards had still not arrived and he grew worried.

"You know Shikamaru, your guards won't come here. They have been indisposed for a small period of time. Now we talk and let us fulfil your curiosity about what I have been doing." she spoke making him tremble at the pain he knew was coming.

The reason was simple. Hinata was a gorgeous woman but a deadly ninja with a frozen heart that had been encased in ice due to the loss of Naruto. No one had been more affected than her and everyone knew it. Now he managed to fit the puzzle that had been plaguing him since last seven years. It was Time for the truth to be released. Hinata made a single hand seal and Shikamaru froze in his place at the unexpected use of fuuinjutsu and cursing to himself at being caught so easily. Two shadow clones of Hinata appeared behind him and bound him up using ninja wire and then delivered a series of jabs making it impossible for him to move and mould chakra.

She nodded to them and then walked up to him and whispered sweetly in his ear making him tremble at her tone, "I have been making research to travel back in time and save my Naruto from his death. Now then goodbye Shikamaru and I hope to see you again when we are children. "

Shikamaru's eyes had widened at the end of sentence and he only had time to grunt in pain before Hinata struck him twice in his head and chest knocking him out. She nodded to her clones who took him to secluded place before she activated her last phase of plan.

Entering the underground lab of Orochimaru in the forest of death, she formed clones which went to destroy all traces of her experiments and the records of her final seal. As she stood in the middle of the massive sealing array she looked heavenwards and spoke, "I am coming Naruto kun. Just wait for me." Flashing through the seals at a pace that even a Sharingan would find insane, she intoned softly when she completed her last hand seal, "Uzumaki Kinjutsu: Gyaku taimuwāpu" (Kinjutsu Reverse Time Warp ) and in a flash of light she vanished to her past.
