AN: An inspirational fanfiction writer once told me that fanfiction is for the author. There's no money, no glory, having thousands of reviews is hardly different than a handful. I hope you enjoy my story :)

Warning: This chapter definitely deserves its MA rating. Direct reference to breasts and Orochimaru's techniques in maintaining hers, as well as an implied lemon at the end, with questionable consent. I don't actually write out the lemon, but it's definitely implied. Also cursing.

The device that saved the world was a video camera.

When Momoshiki Otsutsuki appeared in Konoha and cast the infinite illusion upon the moon, I had been caught by surprise. For all the amazingness of the technique, it didn't have an infinite range, but it did work fast. He lay waste to Konoha within hours, absorbing the entire cities chakra within himself and moving on to other locations to continue his absorption of the world's chakra.

It was only by the virtue of a video camera feed that I had been saved from the technique myself. I had been communicating with a scientist from Konoha's hospital about the possibility of using genetic screening to identify disease risk factors when suddenly his eyes glossed over and the rinnengan glowed in them. The technique was confirmed when a white spear had shot up into my associates back and begun absorbing him.

After that, I only had a few minutes to mentally prepare myself. Sasuke had informed me prior that he and Naruto were going to confront an Otsutsuki clan member who was headed for the world, apparently a relative of the late Kaguya. The destruction of Konoha was a sign they had failed, and with their failure I knew the world was probably doomed. Escaping it had been the right decision, and it was only the forewarning from the video camera that had given me the opportunity to rewind time.

I was holed up in the darkest deepest chamber of my laboratory, the first time I had made it back to Oto since my return in time. Not bothering to deal with the headache of revealing my newfound sex change to my shinobi, I slid past them wearing a deep robe that made my body seem amorphous, informing them to prepare a cursed seal victim, one of the unfortunate souls who I had branded with variations of the cursed seal in hopes of improving it, and bring him to my private laboratory. After that, I was not to be disturbed.

I knew I had to act quickly on restoring Kimimaro to health, placing him on a immune-suppressant medication regiment to counteract the effects of MPA. I resolved to begin working on preparing the medication the moment I was done with my next task.

I hadn't prepare per-se for a trek through time, but I had prepared for an unforeseen event of war. I had been quite worried Naruto or Sasuke would seek to end me for some slight or another, and I would be forced to flee very rapidly and be prepared to defend myself. As a result, I had prepared a "getaway bag", a bag full of storage seals containing tools I'd find useful if I was forced to defend myself on the run. In addition to money and vials of Karin's blood, it contained a large reservoir of DNA samples I or Kabuto had collected over the years.

Part of my peace treaty with Konoha was that I wouldn't cast the Edo Tensei, and it was part of the reason that the wood user Yamato had always been my "minder" after the war, he had developed a sensory technique that would allow him to detect if I cast it.

The plan had been if Konoha had ever turned on me, I no longer had any reason to avoid the Edo tensei, and I'd use the technique liberally to try and preserve my life. Although Konoha hadn't directly turned on me, it had failed me, and I was free to use the technique again. I'd read Kabuto's notes on the jutsu and was certain I could cast it in the perfect form that he had during the 4th Shinobi war, augmented with my sage chakra and Senju wood release.

A test was in order however. I was sure that it would fail, but I simply didn't know anything about how the pure world worked.

I pulled out the DNA reservoir I had stored, and found a small sample of blonde hair labeled cleanly with the words "Senju Tsunade".

I pulled the sleeping man who was bound by the door onto a table, and I began the process of using the technique. Eventually he was screaming in pain as the seals pushed into his skin, eroding his body into ash and reshaping it into the shape of Tsunade, the aged women who had spent time as the Godaime Hokage.

I was shocked. And fucking delighted.

All sorts of calculations flew through my head, the knowledge that I could revive people from the future. An alternate timeline. The implications also swamped me, my mind flittering through the implications. Was I in an alternate dimension? Was there an unlimited number of pure worlds? How could I have revived Tsunade Senju, the implication being that her soul was in the pure world, when I knew she was still alive at this time in the past? I had been hopeful that my DNA reservoir could be used to resurrect people as they died, not that it would allow me to revive the souls of those from a different dimension, my original timeline.

Another implication struck me, the possibility of duplicate revivals, and I immediately flew through to the other side of my laboratory, pulling into a drawer of DNA that I knew I already had. Labeled cleanly was a supply of the Nidaime Hokage's blood from this timeline, a copy I had not brought into the past with me. An identical sample I knew would be in the DNA catalog I had brought with me.

I stormed upstairs, leaving the revived Tsunade inactive, and quickly found one of the bumbling chuunin who I couldn't remember. Probably had died in original Konoha invasion. A lot of the Oto shinobi had.

I instructed him to follow me, and I led him terrified into the prison in which I had kept the inmates who had survived experimentation with my cursed seal. They were a worthless bunch, the majority of them dying when I had either held a tournament to find a replacement body, or when I had sent Sasuke to kill those who had participated in a prison break.

Their lives had already been forfeit in the original timeline, and I felt no qualms about killing them again. I subdued a dozen of them with snakes that I quickly summoned, paralytic poisons and the snakes forming restraints within themselves. Nothing that would stop a real ninja, but enough to subdue the mindless brutes.

I told the terrified chuunin to transport the other 10 to a hallway outside of my chambers in case I needed them, and I grabbed the two closest to me and dragged them behind me as I made my way back to my private laboratory, dragging the soon to be corpses behind me.

I performed the technique again, this time the screaming more quaint as the sacrifices were both paralyzed and thus unable to scream out as their entire bodies morphed against their will, foreign chakra bleeding through them and remaking them entirely. I was in sage mode to ensure the technique went smoothly, and I could feel the intense pain and terror their auras went through as they were remade, their pain, desperation, terror and hate. This was why I didn't like sage mode, feeling the emotions of victims was a buzzkill.

Ultimately though it subsided as the technique finished, and I had standing before me the corpses of two Nidaime Hokages. I activated both of them at once, and both of them opened their eyes.

They stared at me for a few seconds before they turned and looked at each other, confusion radiating off of them. One of the Nidaime's, the one who had been revived from the sample I had brought from the future, showed recognition as he looked at me, and had far more anger and tension in his aura than the Nidaime who had never experienced resurrection.

I immediately deactivated both of them, my suspicions confirmed for the moment. They really had separate souls, and with the blood from the future, I could summon souls from what I know could only assume was an alternate dimension that my future resided in.

I created coffins made out of wood to hold the two nidaimes, and I sent their deactivated corpses underground to await any use I might have of them.

The reincarnation jutsu was ridiculously powerful. A shame I only had use of the technique briefly before Sensei had sealed my arms away, and only briefly again after regaining my arms before Konoha and the Shinobi Alliance had banned the technique. They should've seen the use it had during the 4th shinobi war. The ability to resurrect nearly any shinobi, complete with almost all of their power and knowledge, in a form that was easily controlled, could be used in-mass, and each resurrected minion with infinite chakra and unable to die from normal injury? It was incredible. The shinobi alliance feared the technique, they feared the power it had been shown to have during the fourth shinobi war.

Why they would take the ultimate shinobi technique, a technique powerful enough to allow one shinobi (kabuto) to resurrect men who had been known as gods and use them as his pawns, to wage war on the entire shinobi world at once, was idiotic. They could've used the technique to conquer the world. Hell, they could've used the technique to save lives. Rather than sending their own ninja on missions where they risked death, they could've sent reincarnated shinobi to fight instead. Sure you had to make a sacrifice to perform the technique, but what was the death of a random criminal, a rapist, a murderer who was already convicted to life in prison, against saving the lives of a soldier?

They had been bloody idiots, and it had cost them. I wouldn't make their mistake, and I certainly wouldn't let myself fall into a situation where I was unable to perform the technique.

I had 20 years before Momoshiki Otsutsuki finally arrived in the world, and I'd make sure it was much better prepared.

! ) ! ! (

Staring at Tsunade's corpse, I marveled at her appearance. She was free of the genjutsu she usually wore to conceal her advanced age, but one of the remarkable aspects of the Edo Tensei was that it could revive ninja to their physical prime.

While Tsunade hadn't lived up to her potential, she had been the brightest medical ninja in the history of the world. Perhaps with a few extra decades experience Saukra Haruno may have surpassed her, but the girl had the benefit of inheriting a half-century of medical achivements and scientific knowledge that Tsunade and her generation had already accomplished.

I had never really gotten close to the girl Sakura, she had generally avoided communicating with me, and when she needed my genetic expertise she either delegated a more practical shinobi to communicate with me, or she reached out to Karin.

Tsunade though… She had taken to basic communication with me after the war, we had traded short letters about once a month. We discussed pleasant things, made references to books we had read, commented on world news. She had never forgiven me enough to embrace me again as a friend, but after all she had lost in the world, I suppose she was wiling to at least maintain dialogue with one of the few people left she had ever gotten close to.

I'd attended her funeral, the first time I'd actually visited Konoha after the war. Kakashi, Hokage at the time, had what seemed like a legion of Anbu tailing me throughout my visit. It had been a first step however, and I had begun visiting Konoha with more frequency afterwards.

~ # ~

I activated the edo tensei technique, allowing Tsunade to animate and assume consciousness. Light filtered into her eyes, and I saw her slowly gain the recognition of consciousness.

She stared at me for a few moments, a seemingly calculated glare. I simply stood across from her, waiting for her to make the first statement. I had posed my body leaning against a table, accenting my serpentine curves as I looked upon her with my best predatory grin.

I barely had time to react as she dashed forward, a pinpoint bead of chakra forming in her fist as she barreled it towards my skull. I tried to dodge to the left but she still managed to hit me in the neck, shattering it and sending me flying across my laboratory, the table and machinery in the way barely breaking me as I slammed into the stone wall at the back of the laboratory.

I had barely enough time to heal the broken neck before she was at me again, fist uppercutting directly into my chest as she concaved my body and shattered the stone behind me, sending a deep quake throughout the base.

This time, I took the half-second I had before her next fist came at me to deactivate the technique, the vengeful she-beast had been about to strike my skull with one of her punches. Although I could probably survive having my skull crushed, I'd have to abandon my body and revert into my white snake form, and I did NOT want to do that.

I stared at the first that was a centimeter from my face, as I slowly restored my heart and chest to function. The punch had literally ripped through my breast, shattered my chest bone, and squashed my heart.

This was the kind of shit I had gone into immortality for.

The regeneration ability I had from my Hashirama Senju cells kicked in, restoring my body to a healthy condition, but I noticed that it hadn't repaired my chest. Fuck.

I quickly moved to the mirror and tried sculpting my breasts back into the pleasant shape I had designed for them. As I worked, I cursed the demented she-demon bitch. I had been hoping to fucking talk to her, and her first move was to try and kill me?

I had even been nice, giving her control of herself. Shows how Konoha fucking repays me for what I do for them. Invent the field of genetics? Snore. Serve through a world war, spending decades as one of their best shinobi? Meh. Revive the Hashirama bloodline from extinction, promising to help bring about Konoha's glory? Oh, let's skill the snake traitor. Gosh dang hypocritical pieces of shit, I remembered why I'd been so set on revenge against the power-hating transphobic city that had only hated me for what I was willing to do for its own benefit.

I finished restoring my breasts, the smooth and plump pale skin returned to a pleasant roundness. It sucked like hell that most of my rejuvenation techniques didn't consider my breasts apart of me, and didn't heal them properly.

Before I let my rage at my own body, Tsunade, and Konoha convince me to raise an army of the dead kage to burn the village to the ground, I left the lab with the unconscious Tsunade standing in it. I needed to vent some steam if I was going to have a conversation with my old teammate.

~ ! ~

None of them were a good enough challenge. I had stormed into cursed-seal prison, gone up to the largest and strongest looking one, ripped his cage door off, and gave him a burst of my KI.

He was too far gone into the mindless rage to truly understand the terror he should have felt, and had immediately tried to crush me with monstrous appendages that had been formed out of sage chakra.

He had taken only a second to defeat, a backhanded sage-powered smack crushing his head as it propelled him against the stone wall. They weren't strong enough to be any fun, strong enough to be any fun. I didn't want to simply kill the weak shinobi in my care and I had enough control over my rage to stop me from hunting down the Shinobi I knew could handle a beating like Kabuto and giving him one. He cosmically deserved it for his total abandonment of science in the future, but I knew it'd hardly engender his loyalty this time around if I used him as a regenerating punching bag.

I summoned the Nidaime Hokage, the one from my original timeline, the future, into the large chamber. I gave him primary control of himself, and I dashed forward, summoning the Kusunagi into my hand as I closed in.

To his credit, the Nidaime adjusted quickly to the surprising situation I had thrust in him, quickly dashing aside and dodging a bisecting slice from the Kusunagi. I had my sage mode activated to the fullest extreme and I had swung the sword with enough force it had pierced through the stone ground and gone into the hilt. As I begun to pull the sword out of the ground, I felt a surge of chakra behind me as the Nidaime formed a water dragon out of thin air and sent it barreling towards me. I dodged to the side and brought up wooden pillars from in the ground to pierce through and dissipate the dragon, and I saw Tobirama rush forward and pull my Kusunagi from the ground, turning on me.

This was more like it.

I summoned my second Kusunagi sword, and rushed forward in a dive like a viper, the second Hokage meeting my blade with his own, the clash of the two all-cutting swords sending a sharp and horrifying screech through the chamber. We traded sword blows for a moment, his speed slightly better than mine but my sage-enhanced strength superior, each clash of the swords a sharp ring. It was exhilarating to have an actual sword fight, usually the Kusunagi couldn't be used like this as it would slice through any normal steel sword.

During our sword fight, I noticed Tobirama subtly form an explosive seal I recognized as his endlessy-replicating explosive seal kamikaze technique. That wouldn't do.

If he was going to cheat in the sword fight, so would I, and as I slashed at him with an exceptionally forceful stroke, both his legs bracing to stop the blow, I summoned a massive pillar of wood from the ground to slam into him, sending him careening upwards and smashing through the ceiling.

I dashed upwards, and into the dusky light of the moonlight outside, to be met with a giant wave of water slicing through my wooden pillar and crashing into me, filling the outside with a giant reserve of water. I couldn't see in the darkness of the water but with Sage mode I could detect the location of Tobirama, moving through the water towards me with a grace of a shark.

I flashed through handseals and giant earthen spears begun to pierce through the water, Tobirama expertly dodging but being kept at bay. I allowed my body to take on a serpentine grace as I swam through the water to dry ground and I looked up to see a giant ball of water where Tobirama stood. Amazing, the amount of power to summon that much water was incredible. Already I could see other Oto shinobi approaching the Nidaime and firing techniques against him, trying to subdue him. He turned his attention away from me briefly, and I watched as he ripped through the Chuunin Oto shinobi. He had never fought with the blade of Kusunagi, but he already used it with grace, slicing through the shinobi who came up to him.

I probably should've been bothered that he was killing my ninja, but it was an amazing, almost erotic dance he performed, the merciless slaughter, the raw power.

Erotic? I looked at the Nidaime as he executed more of my Shinobi and I realized that yes, he was a startlingly attractive man. Too bad I couldn't have him.

A thought formed in my head, a dirty and horrifying thought. I could have him.

I quickly ran through a handseal and deactivated Tobirama Senju, a coffin rising up and his body fell slack, the coffin transporting him back to my personal laboratory.

I moved there myself, and summoned Tobirama Senju, his body soaking wet and his abs glistening. I was wet myself, and at that moment I realized I was still half-naked from when Tsuande had crushed through my chest. I usually left my breasts rigid with chakra to avoid having to wear a bra, but I loosened them and allowed them to take on a natural texture. One of the few benefits of making one's own breasts, that they were easily alterable.

I stared at him, and pondered what I was contemplating doing. Would it even work? Could reanimated corpses have sex? I would presume so, given they regained complex kekkai genkai that resolved on biological structure, but I had never tested it. My eyes twinkled with a mixture of scientific curiosity and lust. I had only had sex once since I had transitioned, a common man who hadn't really known what I represented. He hadn't been my type, powerful men were my type, but I had never gotten around to pursuing anyone. Not like anyone would have wanted me, the evil snake-sannin, the transgender freak, let alone trusted me enough.

I eyed Tobirama contemplatively, before another thought struck me. I had two of him. A sinister grin broke across my features as I cleared the examination table and summoned the second Tobirama.

This was an experiment. A totally justified experiment. Right?

Hope you enjoyed the chapter! \\ I know canonically Tsunade is actually still alive during the Boruto era, but that seemed mainly to have fanservice of the old kage meeting. Plot wise she should've been nearly 80 and had sacrificed parts of her lifespan to her regeneration technique.

And hopefully this chapter reminded everyone that Orochimaru is NOT what we would traditionally consider a good character. She may be bent on saving the world, but that's only cause she's in it. The Orochimaru of this story is still the same sociopathic asshole from canon who killed hundreds for science, tried to destroy an entire village out of revenge, and went about kidnapping children to steal their bodies for herself.
