The world of Naruto, once a thriving indigenous planet, could have evolved with a harmonious coexistence of extraordinary powers and advancing technology. However, the arrival of the alien Ōtsutsuki clan drastically altered the course of this planet's development. The first significant change came when Ōtsutsuki Kaguya planted a sacred tree on the planet. After betraying her fellow Ōtsutsuki, Isshiki, she performed a ritual to offer sacrifices to the sacred tree and eventually consumed the chakra fruit herself. Her ideals, however, clashed with those of her sons, Ōtsutsuki Hagoromo and Ōtsutsuki Hamura, leading to her eventual sealing.

Hagoromo, also known as the Sage of Six Paths, later spread chakra across the world. After his son Indra developed the art of ninjutsu, shinobi, or ninja, began to rise to prominence, shaping the history of the world with their battles and exploits.

Kain pondered over the images he had just seen from the system. "It looks like a war is going on. I'm not sure which one though. If it's the Fourth Shinobi World War, I should probably hold off for now. But it can't be—those ninjas were wearing different Forehead Protectors. Konoha, Iwa... This has to be a conflict between villages, not the unified force of the Fourth War."

He recalled that the Fourth Shinobi World War was a massive, cataclysmic event. If he misjudged the timing and got caught in it, he might not even make it out alive, especially with the looming threat of the Infinite Tsukuyomi.

"Since it's still wartime, I should reconsider my initial plan for trading food supplies. I'll adjust the inventory and include more medicines, leaving behind detailed instructions," he mused.

Kain's father had taken him to various private receptions over the years, and he had made some useful connections, including several individuals working in pharmaceutical companies. He could source a large batch of medicines from them, including antibiotics, anti-inflammatory drugs, painkillers, and vitamins, not to mention essential medical equipment.

While Kain could carry a significant amount of supplies into the shinobi world, he faced a critical question: what could he get in return? The currency in the ninja world would be useless once he returned to his own world, and the value of their money would be equivalent to toilet paper in the modern economy. Gold was a potential option, but gold wasn't widely used in the shinobi world, at least not in the anime he had watched.

"The only time gold was ever significant was with the Fourth Kazekage in the Sand Village, and I'm not exactly equipped to mine or trade for gold. Plus, it's too risky to deal with gold just for some returns. I might as well stick to business on Wall Street for that," Kain thought.

His real goal wasn't simply making money—he had plenty of that already. What Kain wanted was access to the extraordinary powers of the shinobi world. Chakra, the energy that fueled the ninjas' abilities, was the most mysterious and alluring power in that world. But chakra was native to that universe, and even if Kain could somehow learn how to extract it, his chakra reserves would likely be minuscule compared to the shinobi born and raised in that world.

"If I want to obtain true extraordinary power, I'll probably need something like Hashirama cells," Kain muttered. He knew that Hashirama Senju, the First Hokage, had cells that were famous for their regenerative and chakra-boosting properties. If he could get his hands on something like that, his chances of gaining real power would increase significantly.

But for now, all of that was still just wishful thinking. He couldn't even determine the exact time period in the shinobi world yet, so making detailed plans was premature. All he could do was focus on his preparations—stockpiling medicines, weapons, and gear.

"Good thing I already know Japanese!" Kain thought with a smirk. That would at least save him from the hassle of dealing with language barriers.

Kain grabbed his phone and called Carl. "Hey, Carl, how's the warehouse and supplier situation coming along?"

It took a moment for Carl, groggy from sleep, to respond. "Kain? Dude, do you know what time it is? The American Constitution protects my sacred right to sleep!"

"It's noon, Carl. Are you still half-asleep? Should I call your dad and tell him you've been gaming all night again?"

Carl woke up immediately, his tone shifting. "Kain! I was just joking, man. The warehouse and the people you asked for are all sorted. I can show you the place this afternoon."

"Perfect. I'll be there in half an hour."

Kain hung up and headed to his father's study. He found an old phone book that listed the contacts of various business associates. Scanning through it, he found the name and number of a pharmaceutical manager he remembered from a while back. He dialed the number.

"Jess? It's Kain Pent. I'd like to do some business with you."

Jess, the department manager, wasn't particularly high-ranking, but Kain held some sway as a major shareholder in a private hospital in New York. For someone like Jess, Kain was a valuable client, especially when the order involved half a million dollars' worth of medical supplies.

After making arrangements with Jess, Kain met Carl in the afternoon to check out the warehouse. It was secure, spacious, and located in a quiet area with few people around—perfect for what Kain needed in the early stages of his plan. Once he had more funds, he'd invest in a network of secure warehouses, but for now, this would do. Too many goods appearing and disappearing too frequently from one location would attract suspicion, so it was crucial to stay under the radar.

With the warehouse rented, Kain dropped Carl off and made his way to finalize the pharmaceutical order. After that, he planned to gather other essentials like food and clothing. In the shinobi world, it wasn't just medical supplies that would be in high demand—if the war he entered was the Second or Third Shinobi World War, food could become just as valuable.

Kain knew he had to establish a foothold in the shinobi world, much like Kado had. But unlike Kado, who died after relying on hired samurai and rogue ninjas, Kain planned to be smarter. He would use modern weapons, firearms, and ammunition to defend himself and expand his influence. Even a Chūnin-level ninja could fall to the sheer firepower of a well-coordinated firearms team.

"Guns may not be as flashy as jutsu, but they're just as deadly if used correctly," Kain thought. Rifles, with their rapid-fire capabilities, could easily match or surpass the lethality of the average shinobi's shuriken. Even a Chūnin without proper defensive jutsu would struggle against a barrage of bullets.

Kain requested a long-term leave from school, preparing to dive into the shinobi world fully. Before setting off, he gave Carl some extra funds to invest in the stock market. War was brewing on the global stage once more, and whether it was oil or gold, there was always profit to be made.

With his preparations almost complete, Kain's mind was already in the world of ninjas. Soon, he would take his first step into a new world filled with both danger and opportunity.
