3rd Person Pov-

Before Tatsuya could understand why Mikasa was looking at him like she saw a ghost, Mikoto ran towards her and hugged her while saying, "It's alright, you'll be able to beat him next time when you're used to your Sharingan." After saying that she realised something and shouted "You awakened the Sharingan".

Mikoto's shout snapped everyone out of their dreams and Yama ran towards them. He looked surprised seeing a five-year-old kid awaken her Sharingan, but what he was more surprised about was that another five-year-old kid awakened a Dojutsu he didn't know about.

Tatsuya looked at Mikasa with a face saying 'What the hell is going on?' She struggled to get out of Mikoto's hug who then started sulking while mumbling something about being a good big sister.

Mikasa said," Just look at your eyes."

Tatsuya didn't understand why but did what she asked, 'System, open the front camera.'

Tatsuya looked at the hologram which showed his face with eyes that aren't his.

'The Ketsuryūgan. Why me? How troublesome. I'll just think about it when those old guys question me later' and this matter was pushed to the back of his head.

While Yama and Mikoto were looking at the Ketsuryūgan with curiosity, Tatsuya turned to Mikasa and asked "How do I deactivate this?"

Mikoto thought 'Just cut off the chakra supply, what's so hard about it?' Although she didn't awaken her Sharingan yet, she was taught everything about it by her family.

Mikasa understood that this is because of his chakra manipulation talent that he doesn't even need to maintain his Dojutsu on his own.

"Focus on stopping the flow of chakra towards your eyes. You probably don't feel it because you are maintaining it without even realising" she said with a smile.

As Tatsuya did just that, he understood that this was done as naturally as breathing that's why he didn't notice, as he stopped this flow of chakra his eyes turned normal. He thanked Mikasa for her help but she waved it off.

Yama then announced that classes will end here and all of the students can go home. He had a lot to report to the Hokage.

While the kids ran towards the gate, Mikasa approached Mikoto and said, " I'll come back later."

"Where are you going?" Mikoto asked as she thought Mikasa must be tired from all the fighting.

"I promised to hang out with Tatsuya before the match." She said to Mikoto while giving a death glare to the girls who tried to approach Tatsuya.

Mikoto looked at Tatsuya, who in return smiled at her. She thought it'll be good for Mikasa to have a friend her age so she asked Tatsuya to look after Mikasa and left.

Tatsuya and Mikasa looked at each other before using the body flicker technique to disappear, leaving the remaining kids dumb folded.

Meanwhile, in the Hokage office, all the clan heads were having a meeting about the unrest happening between the shinobi villages, from the looks of it, another war is inevitable.

In between the serious discussion, the door opened and a Chunin entered. It was the academy teacher, Konishi Yama.

Everyone in the room frowned, needless to say, it's very rude to interrupt a meeting like this, but they also understood that if someone has the guts to barge in like this, something must've happened.

The Hokage, Hiruzen Sarutobi said, "Yama, what happened?"

"Hokage-sama, it's about Uchiha Mikasa and Shiba Tatsuya."

The Hokage and the current jonin commander, Nara Shikado frowned after hearing those names.

"What about Mikasa?"

"What about Tatsuya?"

Two people said at the same time, the first one was the current head of the Uchiha Clan, Uchiha Fukame, and the other was Hatake Sakumo.

Yama understood what they were asking and hurriedly replied, "Nothing bad happened, they both are perfectly fine."

The two sighed in relief after hearing that. Yama then narrated what happened today, and needless to say, everyone in the room was dumbfounded.

Everyone here had different reactions to the news of two five years old kids reaching the level where they surpass most of the Genins.

Fukame and Sakumo were all smiles. A five-year-old unlocking the Sharingan is definitely something that'll make Fukame happy. As for Sakumo, he was just happy that his disciple is doing well. While the current head of the Hyuga clan, Hyuga Hiyashi, almost facepalmed himself after hearing about both of his kids losing to five-year-olds.

But Yama then dropped an even bigger bomb on them, telling them about the unknown Dojutsu that Tatsuya awakened. Everyone frowned hearing about this, while it is good for the village to have a talent like this, having an unknown Kekkei Genkai raises the possibility of them being a spy from another shinobi village. It's very unlikely that any village will waste this kind of talent for something like spying, but it's better to be careful.

Danzo was already making plans on how to deal with Tatsuya in case he turned into a threat to the village. He was very cautious because he knew about the power of the Sharingan, so he won't let someone so dangerous be inside the village if he wasn't sure of who it was, and if he ends up threatening Danzo’s position in the future. Although the Hokage and Nara Shikado are sure that isn't the case, they still need to make it appear that they are serious about it.

After discussing for five minutes, the Hokage said, "Call both Tatsuya Shiba and Mikasa Uchiha in my office right now." to which Yama nodded and left.

While this was happening, the whole village and the Uchiha clan were in an uproar about the new geniuses. All kinds of talk about Mikasa and Tatsuya were going on.

The Hyuga clan, however, was depressed at how the next clan head and the next head of the branch family lost.

Ignorant of what a huge mess they caused, Mikasa and Tatsuya were enjoying their time together.

Mikasa sat on Tatsuya's lap while she leaned back on his chest, Tatsuya had his hands wrapped around her waist. They have been sitting like this ever since they arrived here.

"I really wanna do it," Mikasa said with a voice of longing.

"Not until we are teens," Tatsuya said as he kissed her lips.

"That wasn't very convincing" Mikasa complained for a while but agreed to what he was saying.

While they were having a nice time, Yama came running toward them and was petrified when he saw Mikasa sitting on Tatsuya's lap, looking like she won't get up even if he forced her.

'These two were fighting like maniacs just a while ago, now they look like they've been with each other for decades.' Yama could feel his common sense leaving him, so he decided to get straight to the point and told them about the Hokage summoning them.

'Should we kill this ill omen.' Thought both Tatsuya and Mikasa as a shiver ran down Yama's spine.

"Lead the way," Tatsuya said, one last time squeezing Mikasa in a hug, before kissing the back of her neck. Yama didn't see this as he was already on the way.

After a couple of minutes, they arrived at the Hokage's office. Opening the door, both of them stepped in.

Everyone in the room got their interest piqued as Tatsuya and Mikasa were holding hands. As far as they know, they met today for the first time. How come they're so close already?

Fukame was even more shocked, as he thought 'Mikasa didn't even let a boy near her ever since she was born, she even shooed Fugaku away, her future brother in law, but now she's acting so friendly with someone she met today?'

"I see you two are getting along well," The Hokage said with a smile.

"Indeed, thank you for asking," Tatsuya said with a harmless smile.

"You guys should know why you were called," Sakumo said while looking at Tatsuya.

"What do you mean, Sakumo-sensei?" Tatsuya tilted his head, feigning ignorance.

'He is Sakumo's disciple?' That was what everyone present thought. Sakumo never taught anyone, he didn't even take a team of three Genins, so having a disciple out of nowhere was a surprise for everyone. After all, being picked as a disciple by a Kage tier ninja means that Tatsuya's talent is good.

'Using my name to raise your value?' Sakumo thought. This kid is too clever for his age.

"Mikasa, I heard you awakened your Sharingan?" Fukame asked, even tho Yama told him but he still wished to see for himself. A five-year-old awakening Sharingan was unheard of. Everyone looked at Mikasa as they all wanted to see.

She didn't bother answering, turning towards Fukame, her eyes changed as she opened her Sharingan.

When they saw this, they finally believed what Yama said was true.

"What about your Dojutsu, Tatsuya?" Sakumo said. The Hokage just watched as he already knew the kid was innocent but couldn't do anything.

{A/N- That's what Hiruzen did his whole life, he just ignored this kind of thing.}

Tatsuya looked at Sakumo as his eyes changed to Ketsuryūgan.

Everyone present was surprised at this unrecognisable Dojutsu. Especially Fukame and Hiyashi were shocked when they noticed that this unknown Dojutsu was strong enough to rival the Sharingan and Byakugan, even if they didn't know about its abilities, they were able to sense the power coming from Tatsuya's eyes.

"I have seen this Dojutsu somewhere," Fukame said, gaining everyone's attention.

"You must have. This Dojutsu has a history with the Uchiha clan." Tatsuya replied with his usual carefree attitude. He didn't plan anything for this meeting but his goal was to spout nonsense. Xianxia level nonsense.

"What do you-" Before Fukame could complete what he was saying, the door opened and a man in an Anbu uniform with a fox mask walked in. Shikado was resisting the urge to go and sleep somewhere.

"Anbu Commander, why are you here?" Hyuga Hiyashi asked.

Everyone looked at the Anbu commander as they missed the looks on the faces of The Hokage, Shikado, Fukame and Sakumo. Fukame now understood why the Hokage didn't say anything about Tatsuya being a spy.

The Anbu commander ignored Hiyashi, looking toward Shikado "Why wasn't I informed of this matter, Shikado-senpai?"

Shikado, while trying his hardest not to leave said, "It was just to satisfy those who had doubts about Tatsuya. But now that you're here, it doesn't matter" And the smartest mind in Konoha, the Jonin commander gave up.

"What do you mean that it doesn't matter? That boy is under the suspicion of being a spy from other villages." Koharu said.

"Say something like that about my son again and you're dead." The Anbu commander, or Hayate Shiba to be precise, said while removing his mask.

"Your son?" Not only Koharu, but everyone except the four who already knew were surprised.

Hayate was appointed in the Anbu by the second Hokage when he was 15. The one he swore loyalty to was the village, now that his son was suspected of being a spy, he was naturally angry.

While this was going on, Tatsuya was busy with the reevaluation of his naive looking father. Who knew the ordinary Special Jonin was the Anbu commander. He smiled, thinking of the funny development.

After discussing everything, the only question that remained was what is that unknown Dojutsu?

Tatsuya then explained the history of the Chinoike clan and how they were framed for something they didn't do and the Uchiha clan coming after them.

While this was going on, Fukame was having a headache as he can already see the kid trying to get revenge against the Uchiha. And with the potential of this kid, he doubted the Hokage will let them do anything since the only thing keeping the Uchiha clan suppress was him and the great elder. This was also the reason why they were dealt with by Danzo, by the sudden death of the great elder and the clan head, Fugaku's position wasn't all that stable when he became the clan head.

Tatsuya finished his storytelling session when Hayate asked "How do you know about it?" He didn't stop Tatsuya when he started to explain but was curious about how the kid knew it.

"Mother sealed some memories and her last words inside my brain, the trigger being my Ketsuryūgan," Tatsuya said as Hayate had a sad face, missing his wife who died not long after Tatsuya's birth.

"So kid, do you hate the Uchiha clan?" Fukame decided to get straight to the point without beating around the bush.

"I am not from the Chinoike clan, and they are already down to a few survivors. As you can see, I am close to the Uchiha clan if I say so myself." Tatsuya said while lifting his right hand which was holding Mikasa's left hand.

"How close are you?" Fukame asked.

"She's mine"

"He's mine"

Tatsyta and Mikasa replied while Fukame wanted nothing more than a good drink.

"You do know the Uchiha clan forbid relationships with outsiders," Fukame asked.

"While incest is fun, we have already decided," Tatsuya said like it was natural, thinking about something very inappropriate for this situation.

"Do whatever the hell you please, just pay a visit to the great elder sometime soon" Fukame decided to give up, thinking the kids will get over this game soon enough. And this is Great elder's problem now.

While everyone was enjoying Fukame getting a headache, Tatsuya said something that they didn't expect, "We would like to apply for early graduation."

Graduation straight after getting into the Academy? That's gotta be the most ridiculous thing they ever heard.

Shikado then said, "Very well. Just show the three basic Jutsu that are required for graduation and your knowledge about ninjutsu."

Shikado can see that if he didn't shoo these kids away now, he'll have to do a hell lot of work because of them. Alas, only if he knew he was digging his own grave.

Tatsuya and Mikasa did just that and were given Konoha Headband, signifying their status as Genins.

And so, the graduation record which will never be broken was created.

"What do you want to learn?" Shikado asked so that he can give these troublemakers to someone else.

"Kenjutsu and fuinjutsu for me. Medical Jutsu for her." Tatsuya said while Mikasa nodded.

Fukame sighed again at the sight of the unruly girl who'll beat kids up standing hand in hand with Tatsuya like a loyal wife.

"You already have Sakumo to teach you Kenjutsu but you want to learn fuinjutsu as well?" Shikado thought as to why Tatsuya wanted to learn fuinjutsu.

"Interest," Tatsuya said.

Shikado thought about it for a while before saying, " Hokage-sama, how about Mito-sama train Tatsuya and Tsunade-sama train Mikasa? We can recommend them, whether they take them or not is up to them"

The Hokage thought that this might be able to help Tsunade with her depression after losing her brother and Mito Uzumaki was mostly alone so she might try teaching him as well. "Very well, I'll recommend you two but taking you as disciples depends on them"

Shikado hurriedly said, " It's decided then, you'll be informed about your schedule soon. Until that happens, you'll be under Sakumo. The meeting ends here."

Without any time to complain, Sakumo resigned to his fate and looked at the two kids in front of him.

While this was happening, Tatsuya and Mikasa were looking at the hologram in front of them.

[Get accepted as a disciple of Mito Uzumaki]

[Reward: Fuinjutsu Talent ]

[Additional rewards will be given depending on how the quest is completed]

[Failure: Your Kenjutsu skills will regress from rank C to rank F]

[Accept quest- Y/N]

'You can regress my skills just like that?' Tatsuya thought as he looked at the hologram in front of him.

[The thing that'll regress won't be the Host's actual skill. It'll be the skill that's registered in the Host's Status. The skill registered in the System won't decrease even if left unused. So the Host's Kenjutsu skills will drop to F if the Host doesn't use it for a long time.]

'Oh. Well, accept the quest then.' said Tatsuya in his mind.

While Misaka looked at the hologram in front of her.

[Get accepted as a disciple of Tsunade Senju]

[Reward: Medical Jutsu Talent ]

[Additional rewards will be given depending on how the quest is completed]

[Failure: Your Shurikenjutsu skill will be deleted]

[Accept quest- Y/N]

'What do you mean my Shurikenjutsu skills will be deleted? Unlike other things, I've trained them myself. They aren't even related to my talent.' Mikasa frowned a little. It'll be uncomfortable to lose the skill that she practised herself for some quest.

[The removal means that the skill won't show in the Host's Status. Unlike normal skills, the skills shown in Status won't decrease over time even if the Host doesn't use them. The failure of this quest will remove that privilege from the 'Shurikenjutsu' skill.]

'I see. That's acceptable.' Mikasa concluded before accepting the quest.
