The next morning, Natsu Yuu finished an entire night of chakra training.
He had made some progress, but not much.
He had only managed to refine a small amount of chakra, less than the average Genin.
It was probably enough to use the Transformation Jutsu a few times, and no more.
The main problem was that his physical and mental strength were both weak—he was even weaker than an ordinary person in the Ninja World.
After all, people in the Ninja World had an average of 130 trillion cells, three times as many as people in the real world. Naturally, they could produce far more bodily energy.
But those were all minor problems.
With the system backing him, raising his chakra capacity shouldn't be difficult.
Even if he couldn't raise it, though,
it wouldn't stop him from completing his main mission: unifying the Ninja World.
Every world had plenty of fighters, anyway. He could just let them handle the battles. Unless absolutely necessary, Natsu Yuu wasn't about to risk his life.
Next,
Natsu Yuu washed up quickly and climbed out of the camper van.
Several Konoha ninjas stationed nearby to guard the area were startled and immediately went on alert.
A strange-looking Iron Box had suddenly appeared on Hokage Rock, so it was only natural that Konoha would take notice. But Hashirama had immediately guessed that it was probably connected to Immortal Natsu Yuu, so he had strictly ordered the watching ninjas not to disturb him and to simply keep their distance while guarding the area.
After getting out of the camper van, Natsu Yuu couldn't be bothered to greet the Konoha ninjas.
He simply took out his ninja tool, the Qiankun Cloth Bag, and, before their astonished eyes, stored the entire camper van inside it.
To the Konoha ninjas, this was undoubtedly some kind of advanced Fuinjutsu or barrier technique.
Then,
Natsu Yuu immediately used World Teleportation and left Naruto World 1, ready to find somewhere else to mooch breakfast.
Naruto World 4
At seven in the morning, in front of the home of Minato Namikaze, the Fourth Hokage of Konoha.
Whoosh—
Natsu Yuu appeared in an instant.
"Knock, knock." He rapped on the door.
Natsu Yuu had basic manners. He could have teleported straight inside, but what if Kushina was breastfeeding?
He wasn't some lecherous creep. That wasn't his thing.
A moment later, the door opened.
The one who answered it was Kushina Uzumaki.
"Ah! It's you, Immortal Natsu Yuu?"
Kushina exclaimed, surprised that Natsu Yuu had come to visit.
"Madam Kushina, you've recovered quite well!"
Natsu Yuu remarked with a faint smile. As expected of a pure-blooded member of the Uzumaki Clan.
Her recovery was incredible.
After giving birth last night, she had been so weak she was near death. Yet in just one night, she had recovered most of her strength!
Of course, Kushina had only regained the ability to move around. She would still need a long time to recover her vitality completely.
Even so, it was astonishing.
"That's all thanks to your help last night, sir. Otherwise, Minato and I might not be here now."
Kushina said gratefully from the bottom of her heart. Whenever she thought back to the terrifying events of the night before, she still felt a lingering fear.
"Oh, right. Please, come in."
Kushina promptly ushered Natsu Yuu inside, eager to properly thank the person who had saved her life.
"Where's the Fourth Hokage?"
"Minato? He should still be dealing with the aftermath. He hasn't come home all night..."
The Night of the Nine-Tails was over, but the destruction the Nine-Tails had wrought across Konoha was still immense.
Countless houses had been destroyed, many elite ninjas had died, and a great number of ninjas were injured...
Just dealing with the aftermath was enough to leave Konoha in a complete frenzy.
What's more,
they had to reassure the Land of the Daimyo, suppress the news, guard against enemy attacks, strengthen security, and so on.
Nearly every available ninja in Konoha had been mobilized.
At a time like this, how could Minato, the Fourth Hokage, possibly have time to rest at home?
After returning last night, he had spent a little time with Kushina and Naruto before heading to the Hokage Building to handle the aftermath without sleep.
"Is Naruto all right?"
"Mm. Naruto's fine. He's asleep right now."
At the mention of Naruto, Kushina was overcome with affection, and her eyes filled with tenderness.
At the same time, she felt even more grateful to Natsu Yuu.
Otherwise, after last night,
Naruto would have become an orphan, and he might even have been shunned and targeted by the entire village for becoming the Nine-Tails Jinchuriki.
She didn't care about Natsu Yuu's identity at all. She was simply grateful that he had saved her family!
"That smells good!"
After stepping inside, Natsu Yuu soon caught a delicious aroma.
"I'm making pork bone broth to go with Salt Ramen. It's one of Minato's favorite meals."
Of course, Salt Ramen was actually Kushina's favorite. Minato liked all the dishes she made.
"Have you had breakfast, sir? Why don't you join me?"
"Two servings, please."
Natsu Yuu was more than happy to mooch a meal. He could finally try the food of the Naruto world, and Kushina seemed like a good cook, too.
"Of course!"
Kushina was delighted and immediately set about preparing the meal.
"Sir, did you come to see Minato?"
Kushina asked as she prepared the food.
"More or less."
"Would you like me to contact him?"
"No need. He should be back soon."
Minato had stationed several ninjas in hiding outside to guard the house. They had noticed Natsu Yuu not long after he appeared and had already reported it to Minato.
Minato would probably be flying back before long.
"Oh, all right."
"Um, may I ask you something, sir? Last night, I heard Minato say that the Masked Man who attacked us was Obito. Is that true?"
Kushina hesitated, uncertain.
In the end, she couldn't help asking. She was an impatient person who had never been good at keeping a secret, and this was far too important to hold inside.
"It was him."
"But how could that be? He doesn't look anything like Obito, and..."
Kushina grew more and more agitated.
She had met Obito, and she had liked Minato's student very much.
She thought she knew Uchiha Obito's personality: an optimistic, lively, kind-hearted boy who could even be a little silly.
How could he have become that evil, cruel Masked Man?
It made no sense!
"Let's explain it together once the Fourth Hokage gets back. The reasons are a little complicated."
"All right. Sorry for the trouble, sir!"
Kushina felt a little reassured and stopped pressing him for answers.
Soon, she had prepared four servings of Pork Bone Broth Ramen and brought them to the table.
"Please, sir. Try my cooking."
Natsu Yuu didn't hold back and immediately dug in.
Meanwhile,
elsewhere, inside a conference room in the Hokage Building,
Konoha's High Council was actively discussing how to handle the aftermath of the war.
