After the mission was over, Ryo and Takeru decided to retire as a Ninja. They were too afraid to continue. Both of them lost their best friend in a previous C-Rank mission and in the next C-Rank mission one of them lost his arm. Ryo decided to help his father with his shop and Takeru joined him in the shop as a helper.

Tendo and I had no opinion about their decision. Thus, like this within four months my team disbanded. Hiruzen didn't pair me with any team again for a while. I stopped doing missions frequently as I focused solely on my Fuinjutsu training. Once in a while, I will go on some C-rank missions with other teams and even chunnins to gather some experience. ​​

One year passed in the blink of any eye as I turned seven. I have finally reached the Master level in Fuinjutsu and Minato and Kushina were shocked to see this. Minato had progressed a lot too. He had successfully created the Rasengan ahead of time. Both Minato and Kushina have reached the Grandmaster level In Fuinjutsu.

My Sharingan evolved into three tomoe-Sharingan. I was really happy about this development. I exposed my Sharingan to my family and they were shocked to see my fully developed Sharingan. I just made an excuse that I have seen too many lives and deaths in my missions which acted as a trigger to awaken my Sharingan.

What shocked them more was my unusual Sharingan and father just called it off as a mutation. Such cases were rare in clans as hardly any mutation occurs and the person with mutated Sharingan usually goes blind shortly and in some worst-case scenarios, death may occur. I convinced them that I am fine and there is no harm to my body but they still insisted me on not using Sharingan regularly. I could only agree to their request but I don't need to comply with them.

Now I can start to train my other skills. I started practicing in Taijutsu under Uncle Sakumo. He isn't a very skilled Taijutsu user but his training still benefits me a lot.

'Maybe, I should find Might Duy now. He is the best Taijutsu user of the Shinobi world. Training with him will help me a lot as my body will be able to keep up with his training because of Hashirama's healing factor. I hope…'

To find Might Duy, I sneakily followed Might Guy. Might Guy went to his house which looked more like a hut than a proper house. I guess being a genin didn't earn Might Duy enough money to afford a proper house and also Might Duy practices in Eight Gates which burns him too much that he rests the entire next day.

I saw Might Duy practicing some kicking and punching techniques as Might Guy cheered him from sidelines. Might Duy turns in my direction as he immediately noticed me and instantly appeared in front of me.

'Fast! So, fast! He moved so fast without using any Chakra. I could only see his movements with my Sharingan. Without it, I doubt I could have tracked his movements.'

"Who are you, boy? I can see a vigorous youth in you. But it isn't good to peek on someone."

I scratched my head as I walk out of my hiding place. I have already thought of an excuse to convince him in case I got caught.

"Hello, I am Izuna Uchiha. I am a friend of Kakashi as I train with him. I want to learn Taijutsu and Kakashi told me that someone called Might Guy is the best Taijutsu user he ever met. So, I asked him more about you. I just followed Might Guy to see him train."

I lie with a straight-face as I point in Might Guy's direction.

"So, my eternal rival finally acknowledged him. I am so happy and fired up. I will train ten times more than my usual training."

Might guy start to shed a stream of tear as he hugs Might Duy.

"Youth! This is youth! I will cheer for you Guy. You are still in your youth!"

"Yes, father!"

Both father and son hug each other as they start to shed buckets of tears. I feel embarrassed by seeing their interaction as the atmosphere turned weird.

Cough…cough

I cough slightly to gather their attention as they look in my direction.

"Izuna boy, your youth is blooming. You have entered the spring of your youth. Seeing Guy fired up by your words, you can train in taijutsu with us. Your passion, determination, hard work, and youth will shine brighter in the entire Village. This is youth. But before that, I have to see that you are youthful enough."

I sweat-drop at his remark as weird thoughts enter my brain. I hug my body tightly as I retreat a step back.

"Let me see your youthfulness."

Might Duy walks towards me. I close my eyes to bear the assault, but nothing happened.

Might Duy just walks in front of me as he starts to inspect my body.

"Hum! Good body-fat ratio. Your muscles are compact enough and your body is in your first growth spurt."

He gives me a thumbs up and flashes a wide smile as his teeth gleam.

"Your youth is ready to shine but before that, you need to wear something better to train yourself."

He pulls green spandex from his belt as he thrusts it in my hand. I look at him awkwardly and I instantly reply,

"No, I won't wear this. I already have my training outfit, there is no need to wear anything else."

Might Duy slumps on his shoulder as he depressingly starts to mutter the benefits of this optimal Taijutsu training garment. I ignore him as I approach Might Guy.

"Guy, You are so cool to be able to enter and graduate from academy just by using Taijutsu."

Guy sheepishly scratches his head as he flashes a bright smile,

"It is all because of my youth. I train with my father and he motivated me to move further."

"Ok! Izuna boy, if you want to train with us. Come early tomorrow morning as we will start with a complete round around Konoha on our hands and then we will do the muscle training exercise. I will also make a diet and nutrition plan for you, follow that plan strictly. Now we will meet tomorrow morning."

With this, my hellish training with Might Duo started. When I got used to the normal training without sweating, Duy added weights to my legs and I start to pant again as I started the training in difficult mode.

Looking at the hell mode training of Might Duo, I could only shake my head as I started again.

Three more months passed by as I rapidly improved in Taijutsu. Duy taught me all of his techniques without holding back. Although he never mentioned anything about the Eight Gates. I can understand his sentiment but I am curious to see the technique and if I possible I would like to master it as my healing factor can compensate for the loss of vitality and other harms to the body.

But I doubt that Might Duy will teach me this technique. Well, he spent twenty years of his life creating, mastering and perfecting the technique. How can he pass such a powerful technique to an unknown person? For now, even Might Guy isn't aware of this Technique.

Guess, I have to see the technique for myself and perhaps try to copy it with Sharingan. Normal Sharingan can't copy the technique as Kakashi was able to learn only one gate release. Maybe, it was his body unable to bear the pressure of further gates or his inability to further copy the technique.

Duy practices this technique late at night. I can sneak out from my house and spy on Duy when he uses the Technique and records it with Sharingan. This idea came to my mind and I unanimously thought of putting it in the act.

Later at night, In Uchiha Clan compounds,

Inside his room, Izuna dressed completely in black clothes as he sneaks out from his room,

"Light Style: Camouflage Cloak"

Izuna's clothes start to cover in Light Chakra as his body starts to fade away and he turns invisible.

'I have further perfected my Light Style Techniques and created a few new ones in these past years. Now not even Byakugan and Sharingan can detect me as I am a part of light itself.'

I sneaked out of the Uchiha clan under the watchful eyes of Police Guards as I exited the clan. I walked along the streets as they were empty and jumping on rooftops may create unnecessary noise.

I reach the hut of Might Duy as I see him sneak out. Duy cautiously looks around as his gaze passed by me without any reaction. When he made sure no one is around, he starts to travel deeper into the forest.

I closely followed him without making any noise. Soon he reaches near a small waterfall on the Naka River. Duy stops for a while and starts to look around again.

After awhile Duy starts to do some warm-up exercise to condition his body. Duy clenches his fist as he crosses his hands in front of his chest.

"Haaah….Gate of Opening…..Gate of Healing….. Gate of Life….Gate of Pain…Gate of Limit…Open!"

Might Duy immediately opened five gates out of Eight as he starts to jump and kick for a while. After a few seconds, he concentrated again as his skin turned red and veins appeared on his entire body. His body was releasing a dense blue Chakra as his eyes and body glowed green.

"Haaah….Gate of View….Open!"

A shockwave is released from his body as nearby water starts to displace.

"Aaaah…Gate of Wonder…Open!"

His body starts to secrete blue sweat which evaporates immediately creating a blue Aura that blew nearby trees. I am blown back by the shockwave and almost exposed myself.

Might Duy clenched his fist as he punched slightly in the air. A large crater formed beneath his feet as the compressed air start to take shape of a White Tiger. Before it could form completely Duy ran out of gas as he slumped on the ground and start to pant heavily.

"Not yet, this technique has almost reached completion. I still need a little bit of time to complete the technique."

Duy laid on the ground motionlessly. After a while, snoring sounds could be heard as Duy fell asleep. I return to clan compounds as I start to contemplate,

"The technique is too fast, he opened the first five gates simultaneously. I could only record the opening of three gates. I need to pay him continuous visits for a while to completely understand the technique."

I made this plan as I continued to peek on Duy for the next few weeks.
