Fuinjutsu And Uzumakis

Ryouma's POV:

After literally playing with fire for few hours, I returned home, only to come back with new stuff in two bags.

I opened the first bag and pulled out a file, inside which all the details of my experiments with explosion tags were recorded along with necessary seals to make them.

'Alright time to test out the modified explosion tags.'

The basic model of explosion tag contains a seal around the kanji 'explode'. As the tag is activated by chakra, the seal around the kanji unravels and the kanji is infused with chakra and explodes. The explosion is weak and made out of pure chakra.

So this explosion tag is a waste because of it has low efficiency, requires delicate handling and often malfunctions.

'But I guess the make perfect material for creating new and more innovative tags. Whoever came up with this idea is genius.'

I was saying that because the design of the seal left many places where more seals could be added. It was looking as if it is incomplete in the first place.

I began creating a pit to explode my creations in.

'No way I am testing any of them on the same ground as me.'

In the creation of these tags too, I have taken some of the ideas from my previous life. I was not very educated, but I had worked in military for years.

That aside I personally loved creating these tags, not because I am a wannabe-diedara or something, but because these fuinjutsu tested the limits of my creativity and imagination. I loved just how versatile they are. How you can do just about anything with seals.

'Obviously there are some frustrating and irritating parts as well but they are not enough to diminish my love for seals.'

Fuinjutsu is a very powerful and even more versatile art. It is so versatile that it is almost impossible for a normal person to learn the whole art in one lifetime. And above all it is not exactly easy.

Unlike ninjutsu, taijutsu or even genjutsu, where it is possible to improve the proficiency just by practicing, such things are not possible in fuinjutsu.

Fuinjutsu tested the creativity, imagination and talent for this art of the user to its absolute limit if they want to create new seals or improve existing ones. Even leaning the existing seals is not exactly easy.

Fuinjutsu revolves around the use of symbols, seals, and talismans to manipulate chakra for various purposes. These seals can be applied to objects, surfaces, or even living beings, imbuing them with specific properties or functions when activated.

Fuinjutsu is revered for its wide range of applications, from storing objects or information to trapping enemies or enhancing one's abilities.

Fuinjutsu encompasses different types of seals, each serving a unique function. Storage seals allow ninjas to store objects, weapons, or even people within them, while barrier seals create protective barriers or force fields. Enhancement seals can boost a ninja's abilities, while restriction seals are used to control or limit the movements and powers of targets.

Hence accomplished fuinjutsu users are always an invaluable resource to a village and are treated as such. Even more if they are fuinjutsu masters or grandmasters.

The Uzumakis are undoubtedly the greatest users of fuinjutsu. That combined with their kekkai genkai and high chakra reserves makes them so formidable of a shinobi that despite being a minor village, it took combined army of three major villages to take it down.

'Being on topic of Uzumaki, it is kind of wierd that they have so many kekkei genkai (or weird techniques?) and Senju have none despite both of them being descendents of Asura. Hashirama had a kekkei genkai, wood release but I believe it was more because he was an incarnation of asura and a Senju.

And above all their kekkei genkai are weird too, as they all make use of uzumaki's abundant chakra and vitality. Not to mention their kekkei genkais covered the parts they were weak at.

Iryo jutsu requires high chakra control which is not a strong point of uzumakis so they have Heal Bite.

Sensors are rare and also require high chakra control, though not as much as iryo jutsu, so they have Mind's Eye of Kagura.

And above all, Admanatine Sealing Chains which amplifies and takes their use of fuinjutsu to a next level. It can restrict a nine tails for god's sake. It is mentioned as a hidden technique but I don't think that it is, Karin was able to use it but I don't think she even knew about it considering her background.

It all makes me think if uzumakis used some type of kinjutsu or fuinjutsu to make some of the techniques that uses their abundant chakra and vitality as inheritable by birth. It will make it different from kekkei genkai but also kind of same. I mean if anyone is able to do it, it would be them or those weird jashinists that gave those power to Hidan.'

(A/N: What do you think? It make sense to me.)

'Giving someone weird powers is dangerous enough but making them inheritable is something far out of the world.

This fact alone makes the potential of fuinjutsu larger than fucking ten tails.

I wonder if this is the actual reason they were annihilated.

I won't be suprised if it was to be honest.'

Aside from that, fuinjutsu can be used with combination of various techniques like barrier ninjutsu to create sealing barrier or can be used to create traps.

'I believe the weird ball hiruzen uses to peep in the village is also a product of fuinjutsu.

But the fact I can't believe is that even the ball failed to convince Jiraiya to become hokage. I guess he likes to peep with his own eyes. So their must some issues with the video quality.'

...

Completing the pit, I made some more reassurances to remain completely safe then I sat down on a rock I placed besides the pit so both see what was going on in the pit and be sage too. After that I began my testings.

The very first test was just adding a symbol on original one that converts the stored chakra in to fire chakra.

I filled the tag with chakra and marked it then threw it into pit and made a snake hand sign.

(A/N: I will refer to as hand sign rather than hand seal. Also marking the tag means on only his command will the tag explode.)

The tag below went off and released hot air shock wave in every direction.

'Obviously the symbol can transform chakra nature so in the end it is just chakra but with some properties of fire. Like that time, when Naruto cut the leaf, it was just his chakra exhibiting wind nature that had cut the leaf.'

I noted the results and moved to next test.

This time it had wind converting seal, the explosion created some shockwaves.

Next time it was earth converting seal, the explosion created hardened air shockwaves that did the most damage till now.

'An explosion tag must be using all three of them in some ratios, I need to increase their individual efficiency and add them. Likewise stun tag would use a lightning and air combination while smoke would use fire, water and air combination.

I then tried out few combination I had already made.

'2:3:1 of fire, earth and air respectively gives the best results for explosion tags for now, explosion is compact, but distructive and hot.

While 3:1:2 of fire, earth and air gives a wide range explosion but it is less destructive more hot, suitable for under ground areas where there is a fear of the structures falling on our head.'

I tried some more things like creating a grenade by filling the up a bottle with glass shards and few tags with only earth chakra. Results were such that I definitely didn't want to be anywhere near it.

Next were the variants of stun grenades and smoke grenades but they didn't go as expected.

'Some more modifications are necessary here.'

After testing some more weird ideas that either failed or malfunctioned, I was finally finished with the testing.

'Looks like it's time to move to actual fuinjutsu, I can't wait. Well looks like I have spent noon here, let's go home or mom will be worried.'
