Manhattan, New York.
Hell’s Kitchen.
Konoha Detective Agency.
After personally witnessing Tony announce the closure of Stark Industries’ weapons division, Roy left Los Angeles and returned to his detective agency in New York.
Although he’d accepted Tony’s commission, he had no intention of staying in Los Angeles and providing twenty-four-hour personal protection.
Likewise, Tony didn’t want another grown man following him around twenty-four hours a day.
Forget Roy—even Happy wasn’t assigned to protect Tony around the clock.
So the two of them had reached an understanding.
As long as Tony wasn’t in danger, they would each go about their own business.
If an emergency arose, Tony would contact Roy immediately.
When that happened, Roy would use his “teleportation superpower” to instantly appear beside him.
Roy didn’t actually possess a superpower.
But he really could reach Tony in an instant.
Because he knew the Flying Raijin Jutsu.
After accepting Tony’s commission, Roy had discreetly placed a Flying Raijin formula on him.
It was also thanks to the Flying Raijin Jutsu that Roy could cross the entire continental United States in an instant, traveling from Los Angeles on the West Coast back to New York on the East Coast.
After returning to the agency, Roy sat down behind his desk and opened his status panel.
[Host: Roy] [Ninja Rank: Genin] [Kekkei Genkai: Byakugan] [Jinchūriki: One-Tail] [Ninjutsu: Rasengan, Big Ball Rasengan, Ultra-Big Ball Rasengan, Flying Raijin Jutsu, Shadow Clone Jutsu, Substitution Jutsu, Transformation Jutsu, Body Flicker Jutsu, Body Pathway Derangement, Chakra Sensing, Shield of Sand, Sand Coffin, Sand Burial, Quicksand Waterfall Flow, Prison Sand Burial, Temporary Paralysis Jutsu, Fire Style: Majestic Destroyer Flame, Magnet Release Sealing Jutsu, Tailed Beast Ball, Wind Style: Drilling Air Bullet] [Genjutsu: Demonic Illusion: Hell Viewing Technique, Demonic Illusion: Tree Binding Death] [Taijutsu: Chakra Enhanced Strength, Gentle Fist, Gentle Fist Art: Eight Trigrams Sixty-Four Palms, Eight Trigrams Palms Revolving Heaven] [Talents: Seven Chakra Natures, Hand-Seal-Free Casting] [Chakra Reserves: 12 Kakashi Units — excluding Tailed Beast chakra] [System Storage: Unlocked] Aside from the Rasengan, Big Ball Rasengan, and Ultra-Big Ball Rasengan, all of Roy’s other ninjutsu, genjutsu, and taijutsu had been obtained as commission rewards.
As for the talents Seven Chakra Natures and Hand-Seal-Free Casting, those had come with the Ninja System when it first awakened.
Just as Roy had expected, after becoming the One-Tail Jinchūriki, three additional techniques had appeared in the ninjutsu section: Magnet Release Sealing Jutsu.
Tailed Beast Ball.
Wind Style: Drilling Air Bullet.
Magnet Release sealing techniques were an innate ability of Shukaku, the One-Tail.
The Tailed Beast Ball, meanwhile, was an S-rank ninjutsu possessed by every Tailed Beast.
As for Wind Style: Drilling Air Bullet, it was a ninjutsu that Shukaku had learned himself.
Roy closed the status panel, rose from his chair, and walked to the open area of the living room.
Taking a deep breath, he connected his consciousness to the Tailed Beast chakra and began drawing upon it.
Shukaku, which had no independent consciousness, naturally couldn’t refuse to lend him chakra.
The next second— A tail grew from behind Roy.
It was nearly two meters long, as thick as his waist, yellow in color, and covered in curse-mark patterns.
It looked exactly like Shukaku’s tail.
Gaara had also been a Jinchūriki.
But Gaara was different from other Jinchūriki.
Or, more accurately, during the period when Gaara was Shukaku’s Jinchūriki, the relationship between the two had always been terrible.
As a result, Gaara had never borrowed Tailed Beast chakra the way other Jinchūriki did.
Much less performed a complete Tailed Beast transformation.
However, Gaara had another way of using Shukaku’s power.
Feigning Sleep Technique!
After using the Feigning Sleep Technique on himself, Gaara would enter a deep sleep, allowing the Shukaku sealed within him to fully awaken.
In addition, whenever Gaara lost control of his emotions, the Tailed Beast chakra inside him could leak out, causing portions of his body to transform into something resembling Shukaku.
Back to borrowing Tailed Beast chakra.
There were two distinct forms.
The first caused a physical tail identical to that of the Tailed Beast to materialize behind the Jinchūriki.
The second released red Tailed Beast chakra around the entire body, forming a Tailed Beast Cloak.
When the Jinchūriki of the Two-Tails, Three-Tails, Four-Tails, and others borrowed their Tailed Beasts’ chakra, they tended to favor the first form.
Naruto and Killer B, meanwhile, preferred the second.
From a purely aesthetic standpoint, Roy also preferred the second form.
But for now, instead of covering his body in red Tailed Beast chakra, he had chosen to manifest a tail identical to Shukaku’s.
As everyone knew, Shukaku’s body was formed from sand.
Whenever necessary, that body could directly transform back into sand.
For example, when using the Desert Layered Imperial Funeral Seal.
In other words, if Roy wanted, he could transform the tail behind him into sand at any moment and then use techniques that required sand, such as Shield of Sand, Sand Coffin, and Sand Burial.
Roy first spent some time experiencing what it felt like to have a tail.
Then he transformed the tail, which had been materialized from Tailed Beast chakra, into sand and experimented with controlling it.
Compared to ordinary natural sand, the sand transformed from Shukaku’s tail was not only easier to manipulate, but also moved faster.
Roy wasn’t surprised by the result.
After all, this sand was created through the materialization of chakra.
He dismissed Shukaku’s tail and began testing the second method of borrowing Tailed Beast chakra.
Under his control, red Tailed Beast chakra surged out from within his body and completely enveloped him.
Tailed Beast Cloak!
As soon as the Tailed Beast Cloak covered his body, Roy could clearly feel every aspect of his physical capabilities increase significantly.
This form really is stronger!
After marveling at the difference, Roy stopped drawing upon the Tailed Beast chakra.
The red chakra surrounding his body vanished with it.
Now that he’d experienced both forms of borrowing Tailed Beast chakra, another thought immediately entered his mind.
Full Tailed Beast transformation!
He wanted to experience what it felt like to transform completely into the One-Tail itself!
Without the slightest hesitation, Roy used the Flying Raijin Jutsu again and locked onto a Flying Raijin formula located in a forest outside the city.
After mastering the Flying Raijin Jutsu, he’d secretly left formulas in many different places to serve as teleportation points.
One of them was located in an uninhabited forest more than a hundred kilometers from New York City.
In the blink of an eye, Roy disappeared from his agency in Hell’s Kitchen and arrived in the deserted forest he’d previously used to test the power of his ninjutsu.
After reaching the forest, he didn’t immediately begin transforming into the One-Tail.
Instead, he activated Chakra Sensing.
The Chakra Sensing technique Roy currently possessed originated from the Second Hokage, Tobirama Senju.
It required no hand seals and allowed for precise sensing across a range exceeding five hundred kilometers.
Because Roy had transmigrated into the Marvel Universe, however, the system had made certain adjustments to Tobirama’s Chakra Sensing to better accommodate this world’s power systems.
Originally, it sensed a target’s life intensity and chakra intensity.
Now, it detected life intensity and energy intensity instead.
After confirming that there was no one else within ten kilometers, Roy took a deep breath.
Then he began his full Tailed Beast transformation.
The One-Tail’s chakra erupted from within his body.
At the same time, vast quantities of yellow sand materialized from thin air and completely enveloped him.
The chakra-materialized sand rapidly expanded to a height of dozens of meters.
In the blink of an eye, it took on the form of— Shukaku, the One-Tail!
So this is what a complete Tailed Beast transformation feels like?
Roy marveled inwardly.
Unlike Gaara when he used the Feigning Sleep Technique, Roy’s upper body wasn’t protruding from the top of Shukaku’s head.
Instead, he had completely merged with the enormous body formed from sand.
Or rather— At this moment…
Roy was Shukaku, the One-Tail!
