I'm in Naruto, but the system says I'm in One Piece.

The future Kushina declares, "Minato developed the Rasengan for me! He developed it for me! And I even named it!"

That's indeed the case. In the Minato Chronicles, the Rasengan's initial name was something like...

"The Hikari Ice Cream Inspires Jiraiya's Double-Style Pill." It's both tedious and long-winded.

It was only because of Kushina that the Rasengan got its name.

But Hoshino Yu definitely didn't teach him the Rasengan.

Minato's chakra nature now includes Lightning Release in addition to Wind Release.

So why didn't Minato, with his superb reflexes and dynamic vision, develop Chidori or even Raikiri?

They absolutely had to go and make those meatballs.

Of course, I'll keep doing it in the future, but not now.

Therefore, with Hoshino Yu's guidance, Minato at this time naturally mastered the Chidori, a lightning release ninjutsu without a hand seal.

Aside from being a bit noisy, it is extremely powerful in both speed and strength, even Orochimaru praised it.

As for Hoshino Yu, for the past two months, besides training and doing missions, he has been waiting for the One Piece system missions to arrive.

Since obtaining the Navy Type 6 Finger Pistol, the mission system has not been refreshed.

Hoshino Yu wasn't surprised by this, since there had been a period of time before when no new missions were refreshed, so this time it wasn't unexpected.

As for other matters, he would often visit Sakumo Hatake's house to ask him for advice on swordsmanship, which greatly improved his swordsmanship, no longer limiting him to slashing or hacking.

However, he does lack talent in swordsmanship. Although he has made great progress, this progress is limited to a certain range.

In addition, I also met Sakumo Hatake's wife, who was indeed very beautiful.

However, they were not members of the Senju clan as rumored, but rather members of other minor clans.

There's also the so-called Lightning Release Ninjutsu: Lightning Bird that I mentioned to Orochimaru earlier.

Orochimaru, realizing he hadn't mastered it, simply tossed it into the Scroll of Seals, setting it to S-rank difficulty, placing it alongside other ninjutsu he couldn't learn, such as the Flying Thunder God Technique.

Hoshino Yu said there was no way to solve it, since it wasn't a ninjutsu to begin with, unless you could eat another Rumble-Rumble Fruit, but that was practically impossible.

The two spent half a day at Orochimaru's house, listening to his teachings, before heading together towards the mission hall.

During this period, news about the war became extremely scarce, almost disappearing altogether.

But most people knew that this was the prelude to an impending war.

On the surface, all is calm, but beneath the surface, undercurrents are surging.

They had no idea when war would break out.

Hoshino Yu and Minato arrived at the mission hall, and after looking around, finally chose a mission involving patrolling the border of the Land of Fire and eliminating rogue ninja.

Looking at the mission token in his hand, Minato felt somewhat troubled.

After all, B-rank missions usually involve fighting Chunin or even Jonin, which is generally not something a Genin like him can handle.

Most importantly, he wasn't afraid of his own abilities, but rather that he was afraid of holding Hoshino Yu back and affecting the mission's progress.

"Minato, what's wrong?" Hoshino Yu asked, somewhat puzzled by Minato's current state. "This isn't the first time you've gone on a mission with me, are you scared?"

"No, it's just..."

"I'll hold you back later," Minato said with a helpless smile.

"You can still say that, kid," Hoshino Yu said, putting his arm around his shoulder. "If anything happens, Daddy will take care of it. You just need to come with me and do some quests."

Minato smiled but said nothing more.

Previously, when they teamed up, the tasks they did were mostly C-level missions, and they were all completed relatively easily.

The mission wasn't too difficult; it involved heading to the border of the Land of Fire to eliminate a small number of rogue ninjas and bandits operating in that area, as well as conducting patrols.

There's a high probability that nothing will go wrong.

Furthermore, even if problems arise, Hoshino Yu can cover for them.

If he can't safely take his comrades away, then he'll eliminate all the enemies—that's his ninja way.

The indomitable ninja way.

After getting home and packing his things, Minato was thinking of saying goodbye to Kushina.

Previous missions were usually short, with him going and returning on the same day. This mission was his first time going on a long trip.

Hoshino Yu gave him half a day off, and at the same time, he went to prepare the things he needed to bring.

He no longer wanted to eat military rations or anything like that, and later discovered that the system inventory could even hold any inanimate object.

If you put snacks, barbecue, or other similar items inside, it can also help keep them warm.

Therefore, in order to make himself more comfortable outside, most of the items in his inventory were food.

"Explosive tags, shuriken, kunai, and all the necessary clothing..."

After gathering all his belongings, Hoshino Yu got up and walked towards the gates of Konoha.

He waited for half a day at the end of the month before he finally saw Minato arrive.

"Oh, so you've finished explaining things to your new wife?"

Upon hearing this, Minato blushed slightly. After greeting the gatekeeper ninja, he sped off towards the edge of the village.

Seeing this, Hoshino Yu shook his head helplessly.

This shows how someone forgets their brothers after getting a wife, and is blinded by lust.

......

The location they went to was at the border between the Land of Grass and the Land of Waterfalls, and was also close to the Land of Earth.

There weren't many ninjas who actually defected from Konoha; in fact, only a handful were known by name.

Those who dare to defect at this stage are mostly Chunin who went to the border or even other countries with their teammates to do missions, and were lured by large sums of money before defecting.

The danger itself isn't high; the difficulty lies in the vastness of the area, making it hard to monitor the other side's movements.

Hoshino Yu happens to be a sensory-type ninja, so having him accompany Minato on missions is undoubtedly the best choice.

Geniuses are forged through experience.

Hoshino Yu felt that, given the changes in the world's timeline, doing her best to push things forward was undoubtedly the best option.

So, Minato, who was in fourth grade in the original story, was pulled out early on to do those high-difficulty tasks.

He could accept his friend Minato getting injured during a mission, but he absolutely did not want to see him die on the battlefield.

The two sped through the forest, taking several days to reach the mission location.

The main reason was to wait for Minato; otherwise, given Hoshino Yu's speed, he would have arrived at the mission location much earlier.

At this moment, Hoshino Yu and Minato were hiding in a bush, taking out a map of the Land of Fire and studying it carefully.

"The target of the mission is a rogue ninja named 'Black,' who is a Chunin. He has several bandit henchmen under his command and is based in this area in front of us."

Looking at the vast, dense forest before him, Hoshino Yu spoke again to Namikaze Minato.

"We can't rule out the possibility that the mission intelligence is wrong, so we'll have to rely on our own ingenuity. I'll deal with that chunin, and you take care of the bandits. Any problems?"

"I understand, I get it," Minato said in a low voice.

"Stay close to me."
