Asauchi

Item: Katana

CLASSIFICATION: Zanpakuto

He had his Zanpakuto. 

His nameless blade symbolized that he was a Shinigami. How that would play out in this world was yet to be seen, but having a cold weapon again in his hands gave him a sense of security.

He stretched his hand out, and the sheathed blade materialized in his soft hands. His face contorted as the hilt felt unfamiliar in the child's grip.

He pulled it out of its ordinary sheath and stared at his reflection on the blade. Innocent blue eyes, if you looked close, like real close, you could see the man he once was, Narrow, The faceless assassin.

He re-sheathed the blade and stared at the remainder of his salvation.

Shipwright

Rank: E

A shipwright is a carpenter who works specifically on ships. They are responsible for the building and the repair of the boat, meaning most pirates need them around for the general maintenance of their vessels. Other ships often have them as well.

…..

Shipwright? That had surprised him, but if his memories were wrong, the shinobi world was at least ten times larger than it had been supposed to be, which was the appropriate body of water.

The tuxedo man did warn him.

He gulped.

He inspected the package, noting all the stuff that was obtained. He didn't receive devil fruit or Haki techniques. Didn't the system state those would be bloodlines?

He balled his fists up in preparation, ignoring the pain of shifting his bones. He quickly performed the Kaido Hand seals.

It ended in failure, but he had time, and he continued meticulously reworking and hyper-focusing, a trait that had seen him through his last life. He could do anything if he put his mind to it.

His old self resonated with his efforts.

What were the mistakes? Training.

What was exhaustion? Effort.

What was Pain? Life.

An hour later, his efforts burnt his remaining time, but his harsh training bore fruit that he hoped would help him.

With a strong body and focused mind, he could do more.

He made the seals again, beads of sweat smearing his dirty features, but all that exhaustion vanished when his arms began to glow green. She stared at his raised arms in fascination but lost before a startling rationalization came over him.

Introspectively, this Kaido Incantation seems to activate his Uzumaki cells, reinforcing them, thus allowing his vast life force to overflow with discernible green chakra.

"In for a pound, in for a penny." He thought aloud as he bit into his arm.

His teeth parted flesh directly over the green glow of the healing Kaido technique.

He continued until most of his injuries were manageable. He stopped once he felt woozy and leaned back against the wall.

He panted as he allowed himself time to recover, time that he didn't have, but what choice did he have? To remain here would be foolish. Danzo hoped to remove his ace and empower himself.

He smirked. The customary Naruto snicker emanated from his mouth, his whiskers glistening into a sweat as his mischievous eyes sparkled.

"Bastards," he growled. "They didn't expect me to be able to mold chakra." He knew the original didn't know how to without putting too much into it and causing it to fail. He didn't have that problem. He had a fundamental grasp on his deep chakra reserve.

He righted himself, inhaled, and exhaled, righting his mental state and rapidly beginning to perform the Clone Technique.

Terrible. He thought to himself as the sickly clones exploded in white smoke.

He fell on his bottom and cursed as the filthy water soaked his unmentionable.

Clone Technique

Classification: Ninjutsu, Clone Techniques, General skill

Rank: E-rank

Class: Supplementary

Hand seals: Ram → Snake → Tiger

Efficiency: 30%—> 43%

Thirteen percent increase in a few minutes, he snickered, his mood soaring at his prospects. Unfortunately, the failures took vast amounts of chakra, and he had failed a lot.

He mentally thumbed over his shadow clone technique but shook his head at performing it now. He needed to master the basics and have them high enough that he was an Academy Student passable.

He had an idea.

"System, I need Chakra Pills."

The host has access to the system store; it has everything you need or can purchase, be found, and/or create at any of the villages. This was perceived in your wish and upgraded for efficiency. 

Hadn't this not been his life, he would have been in a wish-fulfillment fan fiction.

The former assassin spent twenty minutes allowing his natural regeneration to start working since he had been static for a while.

The Chakra Increasing Pill

The Chakra Increasing Pill is a pill used by ninjas to speed up the formation and increase of chakra in the body; it can also restore lost chakra. After losing a significant amount of chakra in battle, a ninja can use this pill to replenish the chakra so they can keep fighting.

Even after losing the last drop of chakra from the body, the user can restore it by simply gulping two pills. Notice: Uzumaki requires at least eight pills to replenish their chakra due to the tremendous amount of chakra.

Class: Supplementary

Efficacy 100%

He wanted to laugh as he read the description of the pill.

Efficacy one-hundred percent, his mind had already calculated the implications, A pill that lacked detrimental effects, at least he got the assumption that was the case, there might be a hard limit, but as a Uzumaki, he could consume eight easily, which made it seem like that was abnormal and potentially disastrous for anyone else to do so.

He poured eight pills into his mouth and swallowed with a canteen of system fresh water. His moment of respite lasted a few more minutes before he went right back to the hand seals.

A copy of him appeared. It had slightly discolored hair, but he expelled it and continued not worrying about his mistakes. His mantra was the only thing resonating in his head.

An hour later, he had semi-perfect copies of himself.

He swapped between the other three basic Jutsu, allowing fluidity to build as he trained this infantile body.

Kidō techniques came easier to him, and he had no idea why. However, it also opened up a large variety, as the incantations could be sub-vocalized and held before being released. That's not even taking into consideration the countless stages, but that was for later; he only needed to familiarize himself.
