Flying Thunder God Technique (Please Bookmark)

New York, Manhattan.

Hell's Kitchen.

"Konoha" Detective Agency.

After personally witnessing Tony's press conference announcing the closure of Stark Industries' weapons division, Roy left Los Angeles and returned to the detective agency in New York.

Although he had accepted Tony's commission, he had no intention of staying in Los Angeles and providing Tony with round-the-clock personal protection.

Likewise, Tony did not want a grown man following him around twenty-four hours a day.

Even Happy was not assigned to protect Tony around the clock, let alone Roy.

To that end, they reached a mutual understanding.

As long as there was no danger, they would each go about their own business.

If an emergency arose, Tony would contact him immediately.

Then, he would use his "teleportation" superpower to arrive at Tony's side in an instant.

Roy did not have superpowers.

But he really could arrive at Tony's side in an instant.

Because he knew the Flying Thunder God Technique.

After accepting Tony's commission, he had discreetly left a Flying Thunder God Formula on Tony.

It was also because he had mastered the Flying Thunder God Technique that he could cross the entire continental United States in an instant, returning from Los Angeles on the West Coast to New York on the East Coast.

After returning to the agency, Roy sat down in the chair behind his desk and opened his status panel.

Aside from the Rasengan, Big Ball Rasengan, and Ultra-Big Ball Rasengan, all the other ninjutsu, genjutsu, and taijutsu had been rewards for completing commissions.

As for the two talents, Seven-Nature Chakra and Hand-Seal-less Techniques, they had come with the System's awakening.

Just as he had guessed, after becoming the One-Tail Jinchuriki, three new ninjutsu had appeared in the ninjutsu category: Magnet Release: Sealing Technique, Tailed Beast Ball, and Air Bullet.

Magnet Release: Sealing Technique was an innate ability of One-Tail Shukaku.

Tailed Beast Ball was an S-rank ninjutsu that all Tailed Beasts could use.

As for Wind Release: Drilling Air Bullet, it was a ninjutsu Shukaku had learned on his own.

After closing the status panel, Roy got up and walked to an open area in the living room.

Taking a deep breath, he connected his consciousness to the Tailed Beast Chakra and began borrowing it.

Shukaku, who had no self-awareness, naturally could not refuse to lend him chakra.

The next second, a tail grew from behind him.

It was a solid yellow tail identical to Shukaku's, nearly two meters long, as thick as his waist, and covered in curse-mark patterns.

Gaara was also a Jinchuriki.

But Gaara was different from other Jinchuriki.

Or rather, during his time as a Jinchuriki, Gaara had always had a terrible relationship with Shukaku.

This meant that Gaara had never borrowed Tailed Beast Chakra like other Jinchuriki had, let alone performed Complete Tailed Beast Transformation.

However, Gaara had his own way of using Shukaku's power.

Feign Sleep Technique!

After using Feign Sleep Technique on himself, he would fall into a deep slumber, allowing the Shukaku sealed within him to awaken completely.

In addition, when his emotions spiraled out of control, the Tailed Beast Chakra inside him would leak out, transforming parts of his body into something resembling Shukaku.

Back to borrowing Tailed Beast Chakra.

There were two different forms for borrowing Tailed Beast Chakra.

One was growing a physical tail behind oneself identical to the Tailed Beast's.

The other was releasing red Tailed Beast Chakra to envelop the entire body, forming a Tailed Beast Cloak.

When Jinchuriki such as Two-Tails, Three-Tails, and Four-Tails borrowed Tailed Beast Chakra, they preferred the first form.

Naruto and Killer B, on the other hand, preferred the second form.

Personally, Roy also preferred the second form.

But now, instead of covering his entire body in red Tailed Beast Chakra, he had grown a tail identical to Shukaku's.

As everyone knew, Shukaku's body was made of sand, which could be directly transformed into sand whenever necessary.

For example, when using Desert Layered Great Sealing Burial.

In other words, if he wanted to, he could turn this tail into sand at any time and use ninjutsu that required sand, such as Sand Shield, Sand Binding Coffin, and Sand Burial.

He first experienced what it felt like to have a tail.

Then, he transformed the tail formed from solidified Tailed Beast Chakra into sand and tested his control over it.

Compared with ordinary sand, the sand transformed from Shukaku's tail was not only easier to control, but also faster.

He was not surprised by this result.

After all, this sand was the product of chakra taking physical form.

After dismissing the Shukaku tail behind him, he began borrowing chakra in the second form.

Under his control, red Tailed Beast Chakra surged from within him and completely wrapped around his body.

Tailed Beast Cloak!

As the Tailed Beast Cloak enveloped his body, he could clearly feel a significant increase in all his physical attributes.

This form really is stronger!

With that thought, Roy stopped borrowing Tailed Beast Chakra, and the chakra enveloping his body disappeared.

After experiencing the two forms of borrowing Tailed Beast Chakra, a thought immediately sprang into his mind.

Complete Tailed Beast Transformation!

I want to experience what it feels like to transform into One-Tail's true body!

Without any hesitation, he used the Flying Thunder God Technique once again, locking onto a Flying Thunder God Formula located in a forest outside the city.

After mastering the Flying Thunder God Technique, he had secretly left Flying Thunder God Formulas in many places to serve as teleportation points.

For example, an uninhabited forest more than a hundred kilometers from New York City.

In the blink of an eye, he traveled from the agency in Hell's Kitchen to the uninhabited forest where he had previously tested the power of his ninjutsu.

After arriving in the forest, he did not immediately begin transforming into One-Tail's true body. Instead, he used Chakra Sensing.

The Chakra Sensing he currently possessed came from the Second Hokage, Senju Tobirama.

Without needing hand seals, it allowed precise sensing across a range of more than a thousand miles.

Because he had crossed into the Marvel Universe, the System had made adjustments to the Second Hokage's Chakra Sensing to suit the Marvel Universe, changing the ability to sense targets' life force and chakra strength into the ability to sense life force and energy strength.

After confirming that there was no one else within a ten-kilometer radius, Roy took a deep breath and began Complete Tailed Beast Transformation.

As One-Tail's chakra erupted from his body, vast amounts of yellow sand appeared out of thin air and completely enveloped him.

The sand formed from solidified chakra rose dozens of meters into the air in the blink of an eye, condensing into the form of One-Tail Shukaku.

So this was what Complete Tailed Beast Transformation felt like?

Roy marveled inwardly.

Unlike Gaara when he used Feign Sleep Technique, Roy did not emerge halfway from Shukaku's head. Instead, he fused with Shukaku's body formed from sand.

Or rather, at this moment, he was One-Tail Shukaku!
