Chapter 2 – Prologue Part 2
Pre-Third Great Ninja War
After Namikaze Minato graduated from the ninja academy, he rose through the ninja ranks at a record speed. That was something that didn't surprise anyone, especially not Hiruzen. He had also had his eyes on him for a long time, for different reasons than Kushina and other attractive girls, though. Hiruzen was honestly impressed by how fast he improved, and how strong he was, even before he had graduated. Minato was also someone who Hiruzen had gotten to know, and he had become something of a grandparent figure for him as well. That's why he wasn't surprised by how quickly Minato climbed the ranks. Especially since he was the one who promoted him to chuunin, directly after hearing about how he had saved Kushina.
Having saved her innocence would be enough reason for Hiruzen to promote him, since he wanted to be the one to take her virginity himself, but mainly it was due to the impressive feat of having taken down three jounins on his own. Minato had done so before they could even get out of the Fire Country, and before they could cause any real harm to Kushina. Minato's impressive feats continued as a chuunin. He often got assigned to work together with team consisting of experienced jounin, and they would then often be handed missions that are only intended for the very best. B, A and even S rank missions, were the kind of missions which Minato were mostly assigned to.
Hiruzen knew that Minato was someone out of the ordinary and wanted him to get as much experience and knowledge about how it really is to be a ninja, in this rotten world, as early as possible. Hiruzen would often ask Minato to stay behind in his office, after he and his team had returned to the village, in order to talk with him about his missions. He wanted to find out what Minato thought about the things he may have seen, or done, during his missions. It was during those talks that Hiruzen became certain that Minato would be his choice as their next hokage. He shared his dreams of bringing peace to this world, by ending the unnecessary wars and skirmishes, and all the cruelties that came along with them. Hiruzen would end up promoting Minato to jounin only a year after he had become a chuunin.
The world around them had not stopped, during the year before Minato got promoted to jounin. His crush, Kushina, had also been promoted, by dominating one of the chuunin exams held in Konoha. She was now a chuunin, who was seen as something of a kunoichi prodigy. Her prodigy status also came from the fact that she, along with Minato, was being trained by one of the legendary sannin, Jiraiya.
When Minato graduated from the academy, he first belonged to a genin team, which Jiraiya was the jounin teacher of. Jiraiya's two other students, weren't noteworthy at all, and they aren't even relevant anymore, since they had both given up on being a ninja, only a week after graduating. Jiraiya's training regimen had been too much for them. They just couldn't handle it. Jiraiya was trying to raise his students to become actual ninja, he didn't want to watch over brats who were just playing at being a ninja. Those were the types who would die first in wars. In the end it was probably for the best that they both quit.
Minato was then apprenticed to Jiraiya, who continued to train him. After the incident with those Kumo ninja, who attempted to kidnap Kushina, which happened only a month after they graduated, Jiraiya and Minato's usual daily routine of inhuman training courses, got interfered with. That was due to Minato's promotion to chuunin, which in turn meant that he would be assigned to all those missions, without Jiraiya. That was when Jiraiya started training Kushina instead, who he was already very fond of. Unlike other men, who Jiraiya often referred to as closet perverts, he didn't have any nefarious reasons to do so. It was the complete opposite instead, as the super pervert had started thinking of both Minato and Kushina as his two younger siblings. They had become his family, something he had never really had before. While Jiraiya saw them as two younger siblings, but also as two annoying brats, Minato, Kushina and most others, thought of Jiraiya as a parent figure for them.
Now, just because Jiraiya didn't have any ulterior motives to train Kushina, that didn't mean that he didn't check her out every now and then or didn't have a lot of inappropriate compliments for her. That is just how the super pervert functioned. Jiraiya's antics wasn't something that bothered Kushina though, since that was something he did to literally any attractive woman. It was the Jiraiya that both she and Minato loved, as their overprotective and very perverted, adopted father. She knew that Jiraiya would never ask her something so shameless, such as what Hiruzen had asked her that day, and continues to do on a daily basis, whenever she is not out on a mission. It got so bad that Kushina would have her katana ready, in order to give Hiruzen dangerous threats of castration, whenever he asked her to have sex with him. Obviously that didn't stop him. That was still just her playing hard to get, in the old pervert's mind.
Both Minato and Kushina had also become summoners of toads, thnaks to Jiraiya who had let them sign the toad summoning contract. That was something Jiraiya came to regret, almost immediately after they signed it. The toads took a liking to Minato and Kushina and were overjoyed with the fact that their new summoners weren't degenerate super perverts. In mount Myoboku, the toads started waving flags and signs, with words written on them such as "All hail Minato, down with the pervert!", "Protect princess Kushina, shame the pervert!". Unknowingly to Jiraiya, it was Gamabunta who had started that whole movement against him. (1).
All the toads knew that it was just a joke which they were playing on him, while in turn making Kushina and Minato feel welcomed and appreciated. The toads would always be loyal to Jiraiya, but they sure as hell didn't mind messing with him a little either. They are quite mischievous and as a result, aren't strangers to pulling pranks on people. As you could imagine, they and Kushina, had a blast pulling pranks on whoever they could in Konoha, who deserved it. Often Jiraiya would be the victim of one of those pranks. Even Minato wouldn't be safe from them, but he didn't really mind that.
Minato had made a few new friends while out missions, mostly consisting of chuunins who were a couple of years older than him. The Ino-Shika-Cho trio, consisting of Inoichi, Shikaku and Choza, were the ones he got along with the best. Out of those three, Inoichi were the one who he really hit it off with, as the two of them became very good friends. They were very similar and had similar goals and values. Inoichi also had a girl on his mind, just like Minato.
The girl who occupied Inoichi's thoughts, was a girl who happened to be one year younger than Minato and Kushina. Butao is her name. She was often teased for her name, which was a kind of word play of the word "buta", which means pig. Inoichi, whose name in turn, was a word play on the word "inoshishi", which means boar, could relate to her when it came to the teasing. Even though her name meant pig, she didn't look anything like a pig at all. Instead she was a very beautiful young woman, who had long blond hair, and light teal beautiful eyes. (2).
After Inoichi learned that she had been bullied and teased, due to her name, he started helping her with training, as a way to look out for her. The two of them has known each other for about a year now, and they had become great friends. Inoichi is also working up the courage to ask her out, as he is very interested in that young beauty. Butao in turn, is very much in love with him as well, and she is also struggling with finding the courage to confess to him.
Butao has also befriended another person, during her first year as a genin. She and Kushina had become great friends, after working together on a mission. They would later on befriend another girl, who is one year younger than Butao. Her name is Nara Yoshino, and she is a constant pain in the ass for Minato's other friend, Nara Shikaku.
Shikaku and Yoshino are both from the Nara clan, but they are not directly related to each other. Yoshino is obsessed with annoying Shikaku, as she is always following him around, whenever he is within the Nara clan compound. Yoshino is a very bossy young maiden, who has already declared that she is going to become Shikaku's wife in the future. Shikaku couldn't think of a more troublesome future than that.
Shikaku would much rather marry an older woman, who is a lot more experienced than her. That way he wouldn't have to put any effort into doing any research or learning about sex and such. That older woman could just teach him everything, or just handle it herself, while he just lays down and let the woman do her thing. But Shikaku had a feeling that he would wind up together with Yoshino anyway. Even though he finds her annoying, he can't help but think that she is the most wonderful girl in the village as well. If there is anything which he has learned from his father, then it's that his mom is troublesome and that is women are supposed to be troublesome. Shikaku might as well marry a troublesome woman of his own, he figures. It would also be a "drag" to find somebody else.
Shikaku is someone who Minato respects a lot for his intellect and strategic mind. The man has an insanely high IQ, and is capable of thinking up several strategies and plans, on the spot, when they are out on missions. He is also very chill and relaxed, which is sometimes annoying, but for the most part just means that he is very "chill" to hang out with. He is a good friend, in other words.
Choza is a bit different, however. At first Minato thought he was a rather shy, yet very kind young man. But he later on learned what Shikaku and Inoichi already knew about him, which is that he is just like Hiruzen, a sex addict. Choza would take any chance he could to participate in any out of the village sex activities with his female teammates. Since Choza is a man who is about as wide as he is tall, he is not exactly the most sought after young man.
There are a few women who are aware of certain a certain skill set, which the Akimichi clan are the users of. The Akimichi clan are able to extend and enlarge any part of their body, which is an ability they use to grow their body size in battle. These women, wants him for that exact reason, as they are interested him only because is able to enlarge his penis, to any size he wants. In other words, they are perverted women, who wants to get pounded by a gigantic Akimichi cock. Other than that, Choza has no faults really, other than eating too much. He is also a good friend, but Minato always got along the best with Inoichi and Shikaku.
While Kushina and Minato were training, going out missions and making new friends, Hiruzen and Mikoto took every chance they could to fulfill their evil plan of getting in the way of Minato and Kushina's relationship. They would end up failing horribly every time they tried, though. Hiruzen recalls one of those evenings, which occurred about a half a year after he promoted Minato to jounin. That evening Hiruzen had invited a lot of his friends, family and clan members to celebrate his own birthday. His birthday parties were parties which Hiruzen always hoped would turn into an orgy, with all the beautiful women participating. That never happened though, instead he would have to pretend to act like a decent human being, mingling with people, while making sure he didn't do or say anything that would piss off his wife.
Hiruzen also had two other reasons why he couldn't make too much of a fool of himself at home. During all his years of degeneracy, he had also managed to father two children. They are his daughter, Sarutobi Asuka and his son, Sarutobi Asuma. Asuka is ten years older than Asuma, and she is already a senior in the ninja academy, and is a classmate to Nara Yoshino. Asuma won't start attending the ninja academy for another six years though. Hiruzen didn't want them to learn of his degeneracy so soon, even though he knew it was only a matter of time until they found out about it. Asuka would most likely hear about it, as soon as she goes out on her first mission. (3)
Even though his friends and family were all present, he and Mikoto couldn't help but try their luck. They saw a chance when Minato went to the kitchen to get another serving of food, while Kushina waited for him in the hall way. Mikoto joined Minato in the kitchen, then proceeded to flirt with him immediately, asking him if he wanted to hang out after the party, and so on. Minato was just awkwardly trying to tell her as nicely as possible that he wasn't interested, while a jealous Kushina, glared daggers at Mikoto's back. Even though the two of them still weren't officially dating at this point, it still pissed Kushina off. She had fallen for the young Namikaze at this point, which made her really hate how Mikoto would always flirt with him. Had she seen Mikoto do something like this back during their academy days, then she most likely wouldn't have cared at all.
While Kushina stared into the kitchen in jealousy, as Mikoto got more and more forward with Minato, Hiruzen walked up next to her.
"Looks like they are getting along well" Hiruzen said chuckling.
"Mikoto-chan has always been like that. When will she ever learn that Minato-kun doesn't think of her in that way?" Kushina said, pouting.
"You like him, don't you?" Hiruzen said with a warm grandfatherly smile.
Kushina turned red "I-is it t-that obvious?" she stuttered in response.
Hiruzen nodded "You know, I could help you win him over. I could help you make him jealous of you instead".
Kushina stared suspiciously at Hiruzen, before glancing back at Mikoto, who was now hugging Minato's arm to herself, while Minato started sweating, since he knew Kushina was watching. He also felt extremely awkward about the whole situation.
"How would we do that?" Kushina asked, them immediately regretting asking that, knowing something perverted was going to be suggested by Hiruzen.
"Well, I was thinking I could take you to my dojo next door, then I would take you into my private room, where I could make sweet love to you, which will hopefully result in you screaming out in pleasure, which Minato would hopefully hear" Hiruzen said with a perverted giggle.
"I figured you would say something along those lines.." Kushina said with a sweat drop "You are lucky this is your birthday party, otherwise I would have broken your nose again. You disgusting old pervert!" she barked at him, just before Minato used the Hiraishin to teleport himself next to her. He then put his arm around her back, escorting her back to the others. Mikoto came out to the kitchen, facing Hiruzen with a sigh "I tried.." she dejectedly. (4).
"Yes, I know" Hiruzen said with a sigh of his own "Guess it's just you and me later, like always".
Mikoto stood on her tip toes, giving the third hokage a quick french kiss, before telling him "That doesn't sound too bad either, does it?".
Hiruzen watched Mikoto walk back to the others with an extra sway in her hips "No, it certainly doesn't" he said, while checking her out.
Later that night, Hiruzen made love to his wife, as soon as their guests had left. Biwako fell asleep around 1 AM, which was when Hiruzen headed into his dojo. There he found Mikoto waiting for him, laying completely naked on a bed, inside a room in the back of the dojo. The two of them went at it until 5 in the morning, during which Mikoto had been acting extra naughty and slutty all night, since it was his birthday. The room they had done it in, was a room that he had used for decades, as he would bring his lovers there to have sex with him, while Biwako is sleeping in the house next doors. After their four hours long sex session, the two of them were cuddling, with Mikoto resting her head on his chest.
"Hiruzen, I don't think I want to do this any more" Mikoto said, causing Hiruzen to stare at her in shock "You don't? I thought we had a great thing going..".
Mikoto giggled "I'm not talking about us, I'm talking about what we are doing to Kushina-chan and Minato-kun.".
"Oh" Hiruzen said with a chuckle "You scared me for a second there..".
"Baka, you have made me addicted to you. You're not going to get rid of me any time soon" Mikoto said, while she stared up at Hiruzen lovingly "I just don't want to interfere with Minato-kun and Kushina-chan any more. Those two are meant to be together, and I miss hanging out with my friend. I have been such a bitch towards her lately".
Hiruzen nodded, he had no complaints about that. He knew that they were never going to succeed anyway. He had only made this deal with Mikoto as an attempt to get her in bed. He knew that she would remain his lover after that, since he was so confident in his skills in bed. As for Kushina, he is certain that she is never going to take him up on one of his invitations to have sex with him. There are some women, especially strong beautiful feisty women, like Tsunade and Kushina, who would always refuse him. He respects that about them. Even so, he is never going to stop asking them, because he wants them the most, just for that very reason.
"I agree, even though I'll probably never stop asking that beautiful Uzumaki princess to have sex with me" Hiruzen said with a chuckle.
"Do you like her that much?" Mikoto asked.
"Yes, I would do anything for a night together with her, even if it's just to confirm something" Hiruzen said, remembering his theory about Uzumaki women, and strong kunoichi with a bad temper. He thought those would be the most likely ones to resemble Mito in bed. He was certain they would all be extremely wild and fun in bed as well. He wasn't complaining about his current situation though. Mikoto wasn't a bad lover at all, and he still had plenty of other lovers as well.
"She is beautiful" Mikoto said shaking her head "But as her best friend, I'll do anything in my power to keep you away from her" Mikoto then got up, to straddle him "You will not touch her, you can use any fantasizes that you have about her, on me instead" she said, before she started riding him again. Mikoto had decided that she was gonna stay with Hiruzen, and let go of Minato. She also wished to apologize to Kushina, so that they could hopefully return to being best friends again.
A year and a half more passed like that, with Hiruzen doing his thing with Mikoto and his other lovers, while Kushina and Minato were glued to each other, like a couple, but not yet a couple. That changed when the third great ninja war broke out, as Minato and Kushina finally started dating officially. Hiruzen had dreaded this day, when yet another war would begin, which would bring so many more atrocities to this world. He had done anything in his power to prevent it, but didn't manage to anything more than to delay it
The Third Great Ninja War
The war started as a result of smaller ninja villages, such as the Kusa, Ame, Hoshi and Taki (Grass, Rain, Star and Waterfall) villages, trying to take advantage of the fact that the five great ninja villages was still suffering from all the losses of past wars. It was after Iwa (Stone) entered the war, and started marching towards the Land of Fire, when Hiruzen could no longer allow Konoha to sit on the sidelines. Before he officially declared war against Iwa, Hiruzen headed out to scout the army himself, only taking Minato with him. Minato was his ticket out of there, in case they were spotted or things went wrong. He could use the Hiraishin to get them out of there.
When they got to the borders of the Fire Country and Rain Country, they found the Iwa army of over five hundred men. They had taken over a peaceful village, using it as a temporary camp site or base, while doing whatever they want with the village population. There was a large pile of corpses, consisting of mostly adult men, outside the village. Hiruzen knew exactly who does deceased men had been, as he watched the Iwa army rape women and girls all over the village. They were the husbands, fathers and brothers of the women and girls currently being abused.
"This always happens during war.. Every single time" Hiruzen said in a disgusted tone, as he and Minato was standing on top of a hill, staring down at the village.
"Sometimes outside of war as well, I have seen it before" Minato said with a disgusted expression of his own.
Hiruzen nodded, closing his eyes "Minato-kun, I am going to give you a lesson about what it means to be a ninja of Konoha. Even though I have my shortcomings, as you are very well aware of, since I keep bothering your beautiful girlfriend, there are just some things I can't forgive and never accept. What you see in front of you is one of them" Hiruzen said before his face hardened "Minato, listen carefully!"
"Yes sir" Minato said, listening intently.
"Do you hear it?" Hiruzen asked, as a gust of wind blew past them.
"Only the awful sounds of what is happening before our eyes, sir" Minato responded.
"No listen, more carefully" Hiruzen said, as he finally opened his eyes, grinning "The leaves that are being carried away by the winds, are calling out for us"
Minato tried to concentrate his hearing, but couldn't hear anything. He ended up staring at Hiruzen in confusion instead.
"There are some things a man can never walk away from. It doesn't matter how many warriors you are up against, or how bad the odds are of you surviving. That's what the the leaves are telling me, it's the voice of Hashirama-sensei, calling out to me" Hiruzen then bit his thumb, drawing some blood, before using the summoning technique to summon an old monkey summon, by the name of "Enma".
"War?" Enma asked with a sigh "Here we go again" he added, before transforming into a black battle staff, which Hiruzen grabbed.
Hiruzen then threw the hokage hat at Minato, who caught it, while staring at Hiruzen in confusion "Hold on to that Minato, you might just be the one who inherits it from me. Help me lead our armies, as I command them for another war, then I will let your surpass me as the hokage. Minato!"
"Yes!" Minato saluted, while he hid tears that had started falling from his eyes, due to how happy he was after hearing that Hiruzen wanted him to be next hokage.
"Let's go, let's show these whipper snappers what real Konoha men are made of. It's time I show you who I really am, and that I will never turn my back the on people residing in the country that I have promised to protect" Hiruzen announced, before leaping down the hill.
Minato grabbed a three-pronged kunai in each hand, before jumping after him "Yes, sir!" he said with a wide grin.
Hiruzen and Minato then proceeded to slaughter every single Iwa man in that army, saving the village women and children. After that skirmish, Konoha had of course entered themselves into the war. Soon thereafter, Kumo, Kiri and Suna, would enter the war as well. Suna would end up becoming Konoha's ally, which was something new, since they had been bitter enemies in the past two wars.
Minato would continue to make a name for himself through the war, sometimes by defeating whole armies by himself. The war would end up lasting almost six years, during which time Minato had the time to teach and lose a genin team, get married and become the new hokage. The war was the kind where it could take months between each major battle, meaning that they weren't constantly fighting with the other nations. Although, if you did run into an enemy ninja while out on a mission, you knew that you wouldn't get out of there without a fight.
Two years into the third great ninja war, was when Minato got assigned to become the jounin teacher for a team consisting of three freshly graduated genin. All three of them had graduated early, due to the war. It wasn't unusual at all for academy students to graduate early during war times. His three students were Hatake Kakashi, Nohara Rin and Uchiha Obito.
Kakashi back then, was a very serious and professional individual, who didn't joke around or mess about, while working as a ninja. He was, and still is, a ninja genius who made his teammates and his former classmates, look weak in comparison to him. Kakashi had a good reason to be the way he is, he had seen his father suffer from ridicule at a young age. His father, Hatake Sakumo, who was famous throughout the world as "Konoha's White Fang", had broken the shinobi rules, by going against the objectives of the missions, in order to save a teammate. Kakashi wouldn't let himself end up becoming ridiculed like he had been, that's why does everything by the book. He didn't know that their hokage respected his father very much for his actions. His father was the type of ninja who Hiruzen loved to have working for him, in his ninja force.
Rin was also very professional, but she was a lot kinder and gentle than Kakashi. She was a medical ninja in training, who looked up to Tsunade. Rin was also something of a mediator between her two teammates Kakashi and Obito, who couldn't go five minutes without fighting or arguing. She kept them in line, in other words. Out of all three of Minato's students, Rin were the one who Kushina liked the most. She had started caring for her almost as a little sister.
Minato's third student, Obito, was a very happy go lucky young man, with big goals and dreams of becoming hokage. Even though he had big dreams, he didn't necessary have the skills or potential to reach those dreams. He was the weaker one of the team, while Kakashi was the genius. That's another reason why the two of them couldn't see eye to eye, as their difference in skill often resulted in Kakashi mocking Obito, or Obito insulting Kakashi any chance he got, since he saw him as a rival. The biggest reason for their one sided rivalry stemmed from the fact that Obito had a crush on Rin, who in turn had a crush on Kakashi.
Obito was a very kind and heard working young man, and that was something Minato liked about him. He may very well have been Minato's favorite student. Obito is the grandson to the Uchiha woman, Temari, who Hiruzen had saved all those decades ago. The tragedy that their family has had to suffer, would sadly not end with just that incident. Obito would be the first of Minato's students to get killed during the war, a year after their team had been formed. It was when his students were out on a mission, when they ran into a squad of Iwa ninja. During a skirmish with those Iwa ninja, Obito had sacrificed himself to save Rin, by throwing her out of the way of an incoming huge stone bolder. Sadly, he wasn't able to get himself out of the way in time, and that stone bolder would end up crushing his body.
Before he passed away, he offered Kakashi one of his sharingan eyes, which he wanted Kakashi to use in order to protect Rin. Kakashi had the eye transplanted, with the help of his medical ninja teammate Rin, soon after that. With the help of his new sharingan eye, he helped Konoha win many victories, earning himself nicknames such as Konoha's copy cat ninja, and Kakashi of the sharingan.
As far as Minato and his students were aware, Obito had passed away that day. That had actually not been the case, since Obito had been saved by a very old Uchiha Madara. It was due to Madara saving Obito, that something awful would happen to Minato's female student. A year later, while Obito's body was still being treated, Madara had come up with a way to make sure that Obito would start to hate this world, and Konoha, as much as he did. It involved him seeing his crush, Rin, getting killed and abused, right before his eyes.
During that year before Madara was able to put his plans in motions, by targeting Rin, Rin and Kakashi had also started climbing the ninja ranks, while fighting in the war. Rin had become a chuunin, while Kakashi had been promoted to jounin already.
Kushina had been a jounin for over a year, and she was one of Konoha's most powerful fighters at this point. She was famous for her ruthless killings of enemy men, who all had told her what they would do to her and her teammates if they were to lose to them. On the other hand, she was also famous for how forgiving and soft, she could be towards her enemies that does not scream how they are going to rape her and her friends during battle. She would often let the respectable enemy ninja, along with the younger ones who had been forced to partake into the war, escape her with their lives still intact. Because during that war, Kushina did not lose a single battle. Considering how much damage she had caused to the Kumo ninja force especially, she considered her revenge on that village, over and done with. Kushina's accomplishments in the war, has renewed her rivalry with Tsunade, as Kushina is often compared to the female sannin, and some even said she had surpassed her.
Tsunade in turn, had returned to the village temporary during this year, to participate in the war. It wasn't that she was hungry for war like some kind of warmonger, instead she felt that she had an obligation to participate in the war. She didn't want to abandon her two former teammates and let them fight in the war alone. She also wanted to make sure she could save as many lives as possible this time around, and make sure she wouldn't lose Kushina as well. She is the only family she has got left, after all.
Tsunade had heard people spreading rumors about Kushina having surpassed her, or the two of them being compared with each other. That only served to motivate her, as she would brutally destroy any enemy that dared cross her path. And if she ever had any trouble with an enemy, then she could always count on Jiraiya to have her back. The sannin were completely unstoppable during the war, which made them even more feared by their enemies, and more respected by their allies.
Minato was also unstoppable. The only really tough fight he has fought so far, was against a man called "A" from Kumo and his brother Killer Bee. Minato came out of that battle winning, but he wasn't able to kill those two. Neither did he want to kill them either, because they seemed a lot different from a lot of other Kumo ninja he had run into. He secretly hoped that those two would be the ones who would lead Kumo in the future, since that could help end these wars. Minato had recently invented a new technique, which he used a lot during the war. It was a technique that he named the "Rasengan". (5).
During this year, all of Minato's friends had asked out the girls they were interested in, and was now dating them. Shikaku was dating Yoshino, Inoichi was dating Butao and even Choza had gotten himself a girlfriend. His girlfriend was about as wide as he was, and they both sure did love to eat. Somewhat surprisngly, Uchiha Mikoto, had gotten herself engaged with a young man from the Uchiha clan, Fugaku.
That was the result of an arranged marriage between Mikoto and Fugaku's parents. Since Fugaku is very likely to become the next clan head of the Uchiha clan, due to his father being the current clan head, that was not such a bad deal for Mikoto. Especially since that was exactly what she and Hiruzen wanted to happen. They both knew that their marriage would be a loveless marriage. All Mikoto would have to do was to make sure to give that man a few children, and act like a good housewife during the days. As long as she and Hiruzen uses pregnancy seals, there is no reason why their affair can't continue while it has been, as long as they make sure Fugaku doesn't find about it, and Mikoto keeps him happy.
