BECOME MADARA'S GRANDLE IN NARUTO WORLD
FUINJUTSU TRAINING

Right after the infusion of the chakras, the kanji seal begins to fade as it disappears completely within the next few seconds. Minato hurriedly checked the scroll in his hand. There was a kanji seal on the previously empty paper. 

Minato gaped at seeing this as he looked surprised to see the seal on the paper.

'Eh! Is there something wrong with the seal? Why did Minato seem so surprised? I have a Space affinity, so why is the reaction so exaggerated?'

I started displaying the scroll in front of the stunned Minato as I spoke,

“Minato-san, look I have an interest in the extraterrestrial element. You must train me in the Space element now.”

Minato gathered his wits as he replied,

“Yes, you have an interest in Space. But what surprised me was how high your affinity for space was. It took five minutes of continuous Chakra Supply to transfer the seal completely from one scroll to another. Five minutes is considered excellent for Space affinity, but you just did it in a matter of a few seconds. This implies that your affinity for space is too high. I'm surprised because we from the Namikaze bloodline specialize in Space elements but you are an Uchiha and still have such a strong Space affinity. I wonder what other secrets are you holding?”

Minato looked at me curiously as she joked. I started sweating because I wasn't sure how to reply to this.

"okay! I'll train you in the space element but for Fuinjutsu you have to ask Kushina. Kushina is a Uzumaki and she specializes in Fuinjutsu. Her fuinjuts skills are better than mine.”

I nodded my head at Minato as I walked towards Kushina hoping to convince her to teach me Fuinjutsu. I am not sure how powerful Fuinjutsu techniques are, as there is no Uzumaki who specializes in Fuinjutsu in Anime. But Uzumaki was feared for their sealing techniques to the point that many other countries joined hands with each other to deal with the Uzumaki Clan who spoke for themselves. Kira, I will find out more about the potential of the sealing technique when I learn it myself.

Kushina was chatting with Rin as I approached her. He sensed my arrival as he asked from me,

“Izuna-kun, do you need anything from Brother?”

I hesitated for a while before I started talking,

“Kakak Kushina! I. I have a very high affinity towards the Space Elements. Minato-san just checked it with the Uzumaki scroll. So, I want to learn the 'Flying Lightning God' technique from Minato-san. He agreed to train me in the Space element but asked me to convince you to my training in Fuinjutsu. So, I want to ask you to train me in Fuinjutsu, Brother Kushina.”

"No! I will not teach Fuinjutsu to you Izuna-kun.” Kushina answered directly.

“Eh…! Why won't you teach me Kushina's sister?” I asked while playing my fingers.

Kushina looked at Izuna while thinking,

'Imut! But I won't teach you just because of that.'

“Because Izuna-kun is a bad boy. She won't even let Brother Kushina hug her.”

"What's? Sister Kushina, you would teach me Fuinjutsu if I allowed you to hug me right? ”

I hesitated for a moment before continuing,

“Uhun... Then Brother Kushina... Can you hug me all you want?”

I bit my lower lip as I finished these words.

“Yes! Well, that's Izuna-kun Lucuku for you.”

He hugged me in his arms as I struggled to breathe. His huge mound stuck to my face as I had a conflicted expression on my face,

'Somehow, this is happy but at the same time torturous. I was still a child and my younger brother did not stand out.'

I can't put my hand on it. I shook my head to dispose of such thoughts, as I began to struggle in his arms as I choked. Kushina freed me from her embrace as she spoke,

"okay! Izuna-kun I will teach you Fuinjutsu. But I will hug you every day as my payment.”

I lowered my head when I heard him say these words, but I still nodded weakly at him.

"okay! Izuna-kun let's go shopping first for a start.”

I tilted my head in confusion as I asked him,

“Kakak Kushina, why should we go shopping to learn Fuinjutsu?”

Kushina chuckled as she stretched out her hand and started to pull my cheek as she replied,

She puffed her cheeks as she showed her biceps,

“Kakmu Kushina will soon reach the Grandmaster in Fuinjutsu. Look, am I not amazing, praise me.”

Rin began clapping as I joined her to please Kushina. Kushina nodded to us as she spoke,

"okay! Rin and Izuna go to the Ninja weapon shop to get Fuinjutsu's blank scroll and ink. Later we can also buy some other items when we do. ”

He turned towards Minato as he shouted out loudly,

"Minato!... Minato, I'll borrow Rin and Izuna for a moment."

Minato nodded at him as he took me and Rin in his arms and blinked away to the Village.

After five minutes, we arrived at the village. I started inserting some Chakras as I made some signatures,

'Light Style: Optical Camouflage'

My body faded away as I became invisible. Kushina was surprised when she saw me becoming invisible as she asked, Kushina said,

"Why did you turn yourself into Invisible Izuna Kun?"

I returned it, though,

“Kakak Kushina, I skipped class from the academy. I don't want any instructors from the academy to notice me in this market and report it to Hokage-sama about it.”

"Oh! I almost forgot about it. You are still an Academy student. Now that I realize it, you are so amazing Izuna-kun for your age. Even Kakashi isn't this great at your age.”

Rin was surprised by this statement as she asked, 

“True older sister Kushina, Izuna this is amazing.”

Kushina nodded at Rin as an agreement. Rin muttered something,

'For me, Kakashi is still the coolest ninja with that mask.'

I could hear it as I sweated in his imagination,

'Why do girls prefer the Bad-boy style?'

Kushina goes to the Ninja gun shop when she buys some Fuinjutsu ink sticks and ink stones to grind ink sticks. He also bought many empty scrolls for the practice. After Kushina was done with the Ninja gun shop, she and Rin went to a nearby Kain store when Kushina bought a bunch of new clothes for the next hour. 

I spent the next hour meditating. Fortunately, I was spared the torture that every man had to endure with a sister, girlfriend, or wife. Torture carries a lot of shopping bags. Kushina took out a scroll from her pocket and made some signatures.

Breezy

All the clothes and bags were lost and stored inside the scroll. I wonder if he has such a thing with her, why in the anime did he torture Minato by asking her to carry all those shopping bags?

'I also wanted one of these scrolls, too convenient to use. Guess, I will ask older sister Kushina later for one of these scrolls. In the future, I will be able to design it myself.'

After we returned to the training ground, Kushina took out her Ink Stick and Ink Stone and handed it to me.

“Izuna-kun you have to prepare your own tins while putting them into your Chakramu to control the Fuinjutsu seal smoothly later. I'll tell you the correct proportions of ink and chakra to use in ink preparation. Now, watch and learn.

Kushina started grinding the ink stick on the ink stone while inserting her chakra as she prepared Fuinjutsu ink.

'Right now, I want to graduate from the academy as soon as possible. I had to keep my Sharingan hidden from others. One time, I graduated from the academy and became a genin. I can freely use the Sharingan because I can make nonsense excuses for the awakening of my Sharingan. But, it would be very easy to observe the Chakra with the Sharingan while Kushina was preparing the ink.'

Kushina finished preparing the ink. He took out an empty scroll and started making calligraphy on the scroll.

“Izuna-kun! In addition to ink preparation, your calligraphy skills should also be excellent. When your calligraphy skills are good enough, then you will only be able to write Fuinjutsu seals smoothly. Now, for next week you should focus on preparing the ink and improving your calligraphy.”

To be honest, I had never done Calligraphy before, and being a medical student made my writing worse. My writing looks like the Stampede of some insects and has risen to an almost unreadable level in this life. Difficult days are coming for me, I shouldn't have missed a handwriting repair class in my past life.
