------------

Minato Namikaze was an orphan who became the most feared Ninja in Konoha during the Third Ninja War.

But he was not an orphan, as people thought.

Going back to when she was young, she had always longed for a younger sibling. When one day she found that her mother was pregnant, she was ecstatic.

Times were good and they had even come up with a name for the child upon knowing he was a boy.

They came up with the name Minato.

When the time came for her mother to give birth, tragedy struck; sadly her brother had died while her parents gave birth.

She and her parents were of course both devastated by the information.

For a long period of time, she and her family were extremely depressed. It was only later, when her mother was pregnant again, that her family started to lighten up again.

It was quickly after this time that she met Kato Dan. He had been perfect, and he lit up her world, and the two had quickly started dating.

It was the happiest time of her life, however, fate was cruel to her and her lover was killed during an ambush near the village.

Her life took a complete turn, and with the loss of her lover, she had once again lost her loved one.

From that point, everything ceased to matter to her.

Maybe because of immaturity or because of the trauma that Dan's death caused, she had later made a decision she would still regret.

When she was rummaging through some of Dan's stuff, she found a secret compartment with many data folders. When she scrolled through them, she was shocked to learn that they were all information about human experimentation. When she found that her lover was engaging in taboo research she was appalled but when she saw its goal she couldn't help but be enthralled.

It was an experiment to raise a fetus through genetic cloning artificially. Something that apparently was scarcely salvaged from the remains of Uzushio.

With this technology, the goal of the information was to eventually clone a body and then use a Kinjutsu to implant memories into it, achieving a sort of resurrection. Although Tsunade knew that it wasn't a true resurrection, but for her fragile state of mind, it was a saving grace.

She believed that she could clone Dan through this research and revive him as Dan had even attached a copy of his memories with a Yamanaka. Looking at the reports she found information on the previous lab where the experiments took place.

According to the research, a dead fetus was used as an experimental base due to its genetic composition. She knew she was wrong for it but avoiding the guilt with her goal she continued the research.

Following the report, she aimed to clone the fetus first as a proof of concept before she would clone Dan to perfect the operation.

Through months of testing she had finally succeeded but it was only when she finished had she realized the horror of what she had done.

Seeing the child that looked exactly the same as the child she had seen.

Looking at the perfectly cloned child, she realized that the fetus she had been cloning was her baby brother that had died during birth.

Knowing this she was horrified and immediately threw up. Only after coming to terms with this had she immediately begun to be enraged.

Trying to figure out why someone like Dan was researching the corpse of her dead brother.

It would only be later that she found out that all along Kato Dan had belonged to Shimura Danzo's root and contacting her had only been a mission. The goal was to try to seduce her so that she could be more controllable.

The research she had found was supposed to have been destroyed, but apparently, Dan had been continuing research on it in private.

At that moment, her heart died, leaving her on the brink of death. She had experimented with the corpse of her dead brother for a man who didn't even love her.

Looking at the perfectly cloned and alive baby, Tsunade was at a complete loss.

She thought about destroying it, but she couldn't bring herself to kill it.

Then, she decided to leave him in the Konoha orphanage anonymously with the name of Minato Namikaze in honor of her brother.

When the war ended, she abandoned herself, falling into alcoholism for years. Everything seemed to indicate that she would end extremely badly ...

However, Kato Dan's sister, Shizuka Kato, approached her to ask her practically on her knees to take care of her little daughter Shizuka, since she was terribly ill due to complications resulting from the numerous injuries she received during the war and her brother's death.

At first, Tsunade wanted to lash out for having the gall to ask her to do anything knowing that Kato Dan was the cause of everything.

However, she knew that his sister had no idea what Dan had done and at least she had treated her sincerely. As far as she knew, Shizuka thought she and Dan were a couple. This also fell in line with the Roots Operandi.

And that made Tsunade react since Shizune would eventually be the last blood family that Shizuka would have left since Dan and Shizuka at the time were a pair of refugee orphans from the Fire Nation that with the passage of time converted Konoha to home.

Thinking of this, she decided that although Dan had ruined her life, at least she had made one friend throughout it all.

Perhaps it was guilt for blaming Shizuka for a time, or maybe guilt towards Minato, who she gave away, she decided to comply with the last will of her friend.

Ironically, Shizune was the same age as Minato, whom she hadn't cared to see after leaving him. At that moment, she thought it would be best to take care of him too, so she decided to get him back from the orphanage.

But reality hit her head-on again.

Tsunade organized a test for the children of the orphanage under the pretext of conducting research for a secret project, and since she was a war hero, no one even tried to question her approach.

It really consisted of conducting an interview with a group of thirty children, among whom she made sure that Minato, a little blond 6-year-old who had his tousled hair the same color as her and had inherited his father's intense blue eyes, was the last. The reunion with the fruit of her experiment was perhaps one of the most painful moments of her life…

—--

Tsunade was with little Minato in a room that only had the two chairs on which they were both sitting and the table where the blonde leaned her elbows before the expectant gaze of the boy, who was extremely happy to have the famous Kunoichi so close in that test.

The boy was happy to be part of an investigation that would surely be for the good of the village.

"They tell me that your name is Minato Namikaze …" The woman began expectantly.

"Yes, it's the name Nonou-san gave me" the boy replied smiling.

"I see …" The Sannin adopted a thoughtful expression

"And how do they treat you here? Do you eat well? Are they taking care of you properly?"

Tsunade could barely keep hidden the anxiety she had to know how her son had lived.

"Yes!" Minato was happy "Nonou-san makes sure that we do not lack anything and is very affectionate with us ... That is why I would like to be a Ninja."

"Speaking of which, the reports say that you already attend the Ninja Academy." The woman reviewed the file with the boy's information.

"Yes, I have just started, and the truth is I am very happy because, on the first day of school, I met a very pretty girl named Kushina."

The blond pouted.

"Though I think she doesn't like me ... But I will earn her love someday!" He smiled decisively.

"You'll see that you will get it. You are a very handsome boy." The blonde encouraged her brother "And …" She got nervous.

"In the report, it also says that nothing is known about your parents …"

The woman groped with emotion, thinking naively that the boy wishes he could see his parents and she would confess her version of thought for days, in which she would lie to him saying that she was his brother and that he was stolen after birth and they only recently found him. He must not learn the truth, for her own sake.

However, little Minato's reaction was not what she expected ...

The blonde darkened his gaze and narrowed his eyes, revealing obvious dark feelings. Even Tsunade was slightly scared when she perceived the darkness that those sapphire orbs showed. It was evident that the boy did not like talking about the subject quite a bit.

With growing fear, the woman prepared to wait for the response of her brother when she noticed that there was no sign of longing or something that indicated that it would be a good time to confess the whole secret.

"I'm not interested in knowing, Tsunade-sama …" The boy made clear the resentment he felt for his parents with the severe tone he used.

"They left me here because they didn't want me." He gritted his teeth.

"And I know Nonou-san loves us all, but I can't help feeling like this." Treacherous tears began to leak from her face to the dismay of his sister who had left him here.

"When classes end and I see everyone leave with their parents, brothers, and sisters and I can't help but remember that my parents left me…" The boy closed his eyes with regret.

"That's why I want to be Hokage …" He sobbed before continuing.

"I will not abandon anyone as they did with me!" He clenched his fists.

"I hope I never meet them because I hate them for having abandoned me ...!"

Those last words broke the beautiful woman's heart ...

And without being able or wanting to avoid it, she started crying too. She hugged herself as she realized what her weakness had done to her brother. He was a model boy at school, kind to others, and had the conviction to serve his village, but at that moment it was evident that he had a dark side, which was evidently linked to his origin.

"T-Tsunade-sama… Are you okay?"

Minato regained his composure when he noticed that the powerful woman had burst into tears along with him.

At that moment, he admired her even more, since he believed that she had been empathetic with his pain and thanked her from the bottom of his heart, not knowing the actual reasons for the suffering of the Sannin.

"Y-Yes …" The woman replied still with a broken voice.

"I can't believe there are people who would leave a child as special as you, Minato-kun."

The woman smiled sadly.

"There is no point worrying about those unimportant people. Surely you will never have to deal with those cowards …" She reproached herself for her mistake.

"But always know that you can count on me, never hesitate to look for me if you need help."

"Tsunade-sama…"

To the little boy's surprise, the woman stood up. She approached him to hug him, trapping his head between her generous breasts, causing the boy to blush quite a bit as she rejoiced in the sensation of hugging her brother for the first time since she had left him to his fate at the gates of the orphanage.

"Whenever you need me, never doubt it. I'll be there for you."

The beautiful blonde intensified the hug

"Always …"

"Thanks…"

-----

Throughout her brother's life, she fully kept her word. She taught him a lot about Ninjutsu, Genjutsu, and Taijutsu, in addition to that when he graduated and became a Genin, she got to the point of seducing and surrendering to her friend, the Gama-Sennin Jiraiya, only for him to agree to be the blonde's Jonin Sensei.

That later, the renowned Ninja grew affectionate for the boy was a separate point.

She was close to him, taking due care to avoid being too obvious in her feelings, and for all who knew them, it was a relationship where the famous Ninja sheltered an orphan who she had sympathized with when she did a study in the orphanage of the village. That is why she herself trained Kushina when she learned that she was the object of Minato's affection, in order to help her brother conquer her.

"This will be your room, Tsunade-sensei" Kushina interrupted her teacher's thoughts.

"Thank you, Kushina…" The blonde smiled softly.

"I'll let you rest then. I imagine you're tired from the trip."

Kushina left the room after bowing respectfully.

Tsunade began to see the place with a bed, a dresser with a wide mirror, and a desk. She sat on the edge of the bed and smiled sadly, thinking that Menma was technically her nephew.

She remembered the moment she cared for her student after the incident with the Kyuubi and that baby that Kushina had in her arms.

Once she was barely sure that her daughter-in-law would survive that strange incident where the Kyuubi was released from inside her, she left Konoha without looking back. Knowing that she had once again lost somebody important struck her heart.

She certainly had returned to her home to give herself a break from the debt collectors who sought her out for all the money she owed on the loans she never repaid. But it was also true that she wanted to see her beloved student and above all, that child who was all the blood family that she had left ...

And unknowingly, that was her downfall.

—--

Tsunade was fast asleep, a soft smile on her face as she felt close to the son of her brother. She wanted to meet him and help his mothers care for him to somehow alleviate the guilt for leaving Minato that she had never overcome.

She woke up drowsy when she felt something cold on her neck.

"W-What is it?" She murmured, puzzled.

"Hello, Tsunade-sama…"

The woman's eyes snapped open to find the image of her nephew on her, with her knees on the bed and on either side of her belly. Bewildered, she met the boy's gaze, her beautiful almond eyes meeting the crimson orbs of the Uzumaki Prince.

The woman shuddered at that disturbing vision and her gaze soon revealed the bewilderment.

"W-What ...?" She whispered weakly, feeling herself fall under the influence of the Uzumaki Heir's Sharingan

"Don't worry, soon you'll remember this moment with glee…"

The Prince said with a sinister smile as he placed his hands on her head.

"H-How?" She could barely outline with a small voice.

"You will know soon ..."

Menma murmured close to her ear.

"N-No…" She could barely shake her head, invaded by bewilderment.

Then, before her willpower was completely sapped she felt the Uzumaki Prince slowly turning her head to the left.

She tilted her eyes slightly to notice the presence of Kushina and Konan behind the boy, stiffly erect and arms to their sides.

Their eyes reflected the same three-bladed Sharingan that was breaking down the defenses of her consciousness.

The women wore revealing white lingerie sets consisting of thin stockings held up with garters, slim panties, and revealing lace bras that revealed their new, athletic bodies.

She fought fiercely to maintain control of her brain with her willpower alone, feeling that she was not able to control her own Chakra and use it to overcome the assault.

She did everything she could, but soon her willpower diminished due to the great strength that her nephews' eyes had as well as the power exerted directly on her head by the Kinjutsu attacking her mind.

After a few minutes, her mind was invaded and subdued. Letting Menma see in her eyes the slowly rotating red orbs.

"Finally, Tsunade is within my grasp ..."

He muttered triumphantly when the beautiful female stopped resisting.

The face of the beautiful blonde was losing expressiveness little by little until all that remained was a neutral face and the Sharingan reflected in her eyes.

Menma sharpened his smile when he learned that his surprise attack against the powerful Kunoichi was successful, since in a head-on confrontation, he still did not have the ability to face her.

Certainly, Tsunade was too valuable a target because despite being in diluted form, she had both Uzumaki and Senju blood, and she also possessed very advanced medical knowledge. Her fame was not mere lip service, since through the memories of Kushina, he was able to see in detail several of the blonde's medical feats during her prime.

Now all that ability was now at his disposal.

Celebrating his triumph, he began to knead the enormous breasts of his future slave while he thought about the possibilities of the future ...
