A/N:- Ok, stop complaining. We will deal with Sin Seal now, It won't hinder Izuna in anyway. But some of you might not like the way I dealt with it. I am writing this story with Boruto in my mind. Isshiki Otsutsuki cream-pied Full power Naruto and Sasuke with only a kick while only using around a tiny bit of his power. I need to add some other elements to make Izuna more Op.

--------------------- ​​

A month passed by, Sasuke is finally born.

Fugaku threw a large party to celebrate the occasion. They invited nearly all clansmen and other clan heads to the party.

I attended the party together with my family. Even Minato and Kushina got an invitation. Well, Minato is Hokage and Kushina seemed to be a close friend of Mikoto.

Baby Sasuke looked way too cute. Itachi carried Sasuke in his arms and Sasuke giggles.

'Bro-con! Itachi is a bro-con.'

I remarked at their interactions. I have grown up from the stage of molestation by the frantic group of aunties and Grandmas. Itachi can avoid this because of Sasuke.

'I won't allow Sasuke to turn into an Emo again. Look at this cute child, some schemes of Danzo or Obito can 't ruin him.'

I tickle Sasuke slightly on his cheeks. Sasuke grabbed my finger and giggle.

"Nii-san, he likes you." Itachi and Shisui remarks.

Itachi seems to hesitate on something as he silently mutters to himself,

'But I am his real brother!'

I sweat-drop at Itachi.

'I can hear you, Itachi.'

We are interrupted by some disturbances; I turn around and get freaked out by creepy Hyugas. Hiashi and Hizashi appeared with a bunch of Hyuga elders.

I spot two pretty Hyuga women with them. One of them is holding a small kid in her arms.

'If my guess is correct, then they are the wives of Hiashi and Hizashi and that small kid is Neji. He is about to turn a year old.'

Mother, Aunt Mikoto, Aunt Fumiko, and Big Sister Kushina welcomes them as they form a lady union of their own.

'There are only two creepy things in the village which can freak me out. First is Hyuga with their Byakugan and second is Aburame's with their insect littered bodies. I still can't get used to them.'

Another commotion occurs and speaks of the Devil. Aburame clan members have arrived. Shibi walks near me and asks,

"How are you doing, kid?"

"You remembered me, Shibi-san," I question him.

"You were too outstanding to be forgotten. Also, everyone in the village is aware of 'Silent Shinigami'. You are quite famous kid." Shibi answers me as he moves on to greet Fugaku.

Similarly, Choza arrived with Akimichis and greeted me. With the arrival of Hiruzen, the party starts as it turns quite noisy.

Sasuke cries in agitation. I tickle his cheeks to cheer him. Itachi grudgingly looks at me. I ignore him as we walk to a quiet corner.

The party continues as the celebration lasts until midnight.

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

The next day,

I pay a visit to Big Sister Kushina. Kushina is surprised by my visit and she pretends to be upset at me.

"Big Sister Kushina, how are you? I really missed you."

Hmph…

Kushina snorted as she ignored me. She starts to mumble to herself.

"Izuna has been a bad boy recently. He has already forgotten about his Big Sister Kushina, if not he would visit her often. Sob…sob…I missed him so much."

I try to appease her,

"It wasn't my fault, Big Sister Kushina. It is all Minato-san's fault. He has given me lots of missions recently. I hardly have any vacation in between them." I sigh and puts all blame on Minato.

'I am sorry, Minato-san. Bite the bullet this time.'

"That Minato. Wait for him to return home. I will give him a piece of my mind. There is no dinner for him today."

Kushina angrily gnashes her teeth.

'A moment of silence for Minato-san.' I close my eyes to pay my respects to Minato's poor soul.

"Anyway, Izuna-kun, what brought you here? You aren't here to just meet me, right?" Kushina glares at me as she questions me threateningly.

���Have she figured out my lie? I have to act natural.'

"What are you talking about, Kushina Nee-san? I just came here to pay a visit to you, since I was free." I try to convince her.

She smiles at me and walks up to me. She grabs and twists my ear.

"Aww…aww…it hurts Kushina nee-san."

"Give me a hug and I will consider it even."

I grudgingly comply with her. She hugs me tightly and snuggles with me.

"You are the only person left after Obito and Rin's departure. Don't die too early." Kushina hugs me, a drop of tear falls from her eye.

I just allow her to embrace me for a while to calm her down. I console her for a while.

"Ok! Izuna-kun, now tell me the real issue."

"Big Sister Kushina, I want to investigate the remains of Hidden Eddy Village or Uzushiogakure. I have a hunch that it involves many suspicious things with the Uzumaki clans' extinction.

Also, I want to know more about Fuinjutsu as I have already reached the Grandmaster level in Fuinjutsu. I think there is much more to Fuinjutsu and I can still progress further."

Kushina immediately congratulates me,

"Congratulation! Izuna-kun. It seems that your talent in Fuinjutsu is even higher than many direct descendants of our Uzumaki Ancestor. It can be considered comparable to the Great Ancestor.

It took me around five years to reach the Master level and another seven years to reach the Grandmaster level. Minato surprised me a lot when he took the same amount of time as me. But you Izuna-kun, you reached Grandmaster level just in four years.

That is a monstrous rate of progress, even according to Uzumaki standards. You are such a little monster, Izuna-kun."

Kushina hugs me again as she snuggles with me. After snuggling for a while, she leaves me from her embrace as she continues,

"I had my own doubts, too. My Uzumaki clan got annihilated despite the protection of Konoha and Grandma Mito. I investigated this matter for many years, but I still couldn't figure out the identity of the Culprit.

If you can find something from your investigation, then sure I will help you."

I question many things regarding the Uzumaki clan from Kushina, and she answered all of them.

"I have one last question, Kushina nee-san. I would like to ask about the origin of the Uzumaki clan. From Uchiha's records, I came to know that Senju and Uzumaki were blood-related. At some point, they separated into these two clans.

I would like to know the exact details of the origin of the Uzumaki clan. If you are fine with it, then please answer my question."

I am really curious about the origin of the Uzumaki clan. There is no clear cut mention of their origin in the original story. I wonder what there origin story in this world.

Kushina nods and answers me,

"This is not much of a secret, as my clan is almost extinct now. There is no harm in telling you. Also, even I am not sure about the origin of my clan, but from various rumors which I heard as a child, I have some idea about our origin.

A few centuries ago, one of the direct descendants of the Senju clan left the clan as he had no talents for Ninjutsu or Genjutsu. The ancestor journeyed through the entire world and finally found his talent in Fuinjutsu.

There are various stories about his fortuitous encounter, one of the states that he found a certain artifact which granted him the knowledge of Fuinjutsu and was the reason for the long-lives and an extensive amount of Chakra of Uzumaki's.

Another story states that at some point during his journey, the ancestor made a summoning contract with Reaper which blessed him with large amounts of Chakra, a long-life span, and the knowledge of Fuinjutsu.

I am not entirely sure of the details, but these are the various stories and myths I heard during my short stay in the clan. If you want, I can give you the sealing formula to access the Uzumaki clan compounds present in Konoha. They were previously maintained by Grandma Mito, and I stayed there for a while before moving with Minato after our marriage.

There is also an Uzumaki shrine located on the outskirts of Konoha, which was built by Grandma Mito to honor our ancestors. You can also pay a visit to it. I will also give you a map to the location of Uzushiogakure as it is hidden in the Land of Whirlpools.

Without a proper map, you will get trapped in the whirling death pools of the Village. There is only one correct way to access the village."

After searching for a while, Big Sister Kushina hand over a scroll and a map to me.

"Use this scroll to access the Uzumaki compounds and the Shrine. Also, stay safe during your journey and inform Minato about your departure."

I walk out of her house as I start to inspect the key to the barrier formula of Uzumaki compounds.

'This is quite a complex formula, even more complex than the barrier of Village. It will take me a lot of time to decipher this formula. I guess Mito Uzumaki was at the pinnacle of Grandmaster level in Fuinjutsu.'

I stow away the seal and map as I return home. Tomorrow, I will start my journey to Land of Whirlpool and hopefully, I can find a solution to the 'Sin Seal'.
