The Gate to the Extraordinary World

"Ultimately, you only wanted to covet my power."

Kaguya knew exactly what Gato was thinking. To her, those thoughts were not even worth noticing.

What Gato wanted was nothing more than a way to obtain extraordinary power. For her, that was effortless.

What she had to admit was that everything Gato said was true. Helping each other was the best choice.

"Hmph. The wishes of insects truly are insignificant."

Gato listened to Kaguya's mockery with a smile. Didn't that mean Kaguya had agreed? A lofty goddess had fallen on hard times and had no choice but to compromise with him—wasn't she allowed to act a little tsundere about it?

"I will teach you how to extract chakra. The power of the God Tree cannot be revealed in the slightest for now, so you can only start from scratch. This body has been influenced by it to some extent, so the process should go smoothly."

"I see. You're so certain I can extract chakra? This world is different from the ninja world, after all."

"Fool. Did the ninja world originally have chakra?" Kaguya spared no effort in mocking Gato. "Chakra is potential inherently contained within every person. It is energy extracted through special means after the spirit and body have been trained, and it can be combined with techniques to release ninjutsu."

"I see, I see. I was worried that chakra might not be extractable in this world, or that it would be rejected. But since chakra is power that comes from oneself, there's nothing to worry about."

Gato was in an exceptionally good mood. Not only had he escaped a life-or-death crisis, but he had also gained an opportunity that came only once in a lifetime. Still, being mocked so much was frustrating. He knew he would only get snapped at if he kept talking, so he quickly gestured for Kaguya to begin.

Even ordinary people could easily come into contact with methods for extracting chakra, but Gato had never placed any hope in it and had not bothered to learn about it.

Others began training when they were only a few years old, yet most could only become Chunin in the end. Only those somewhat more capable could scrape by as Special Jonin. Gato had been nearly forty when he crossed over, and he did not have the slightest foundation as a ninja. What could he possibly accomplish?

Expanding his business into the Hidden Leaf and preparing to befriend the protagonist group was the proper path.

Besides, in the ninja world, even slightly advanced ninjutsu was tightly restricted. Even within ninja villages, only a limited number of low-level ninjutsu could be freely passed around.

Even if ordinary people had chakra, they could probably only use a few Clone Techniques.

But things were different now. This body of his looked quite young, and the progenitor of chakra, the Rabbit Goddess Kaguya, was right inside him. With the help of such a bug-level figure, if he still could not become stronger, then he really would be utterly useless.

With Kaguya's help, Gato successfully extracted his first portion of chakra.

This chakra was still extremely weak. Compared to the explosive power after consuming the God Tree's fruit, it was like a firefly before the blazing sun. Yet this was power that truly belonged to him.

"Thank you." Gato said it with genuine sincerity. Though this was more like a transaction, no matter what, Kaguya had helped him realize his dream.

"...Human, has this made you so full of yourself?"

"No, I'm sincerely grateful to you, Lady Rabbit Goddess."

Rabbit Goddess. It had been a long time since Kaguya had heard that title. Ever since she stopped being benevolent and began slaughtering all those who dared resist her, the title had gradually become the Rabbit Demon.

"Enough chatter. Are we continuing or not?"

"Of course, of course. I'll be in your care."

Kaguya was somewhat speechless. The man who had just been arguing with her so reasonably had suddenly become so strange. There was a Chinese term that perfectly described Gato's current state—bootlicker.

Having been taught a power he could not have obtained even if he had spent his entire fortune, what did a little flattery matter to Gato?

His merchant mindset had long since taken root: if you benefited him, then you were God. He had as much free gratitude as anyone could want.

Kaguya continued sensing the attributes of the newly generated chakra within Gato's body, and the result sent Gato into wild delight.

"Three attributes from the very start? Hahaha, I really am a genius." Kaguya told Gato that his chakra naturally possessed the attributes of wind, fire, and lightning.

There were actually two systems for classifying chakra attributes. One was the basic Five Elements classification: wind, water, earth, fire, and lightning. The other system was more mysterious, divided into yin and yang.

Kaguya Ōtsutsuki's Bloodline Snare was the supreme divine art obtained by perfectly mastering all seven chakra natures from both systems and fusing them into one.

But that was far too distant for Gato. It was not something he needed to consider right now.

Kaguya's disdainful voice rang out. "Despite being influenced to some extent by the God Tree's power, you still haven't even mastered all five basic elemental attributes. Mortals truly are limited to this extent."

"Hehe, whatever works. Please continue, continue."

Kaguya no longer wanted to say another word to this bastard. She desperately wanted to cut off all contact with Gato.

"I will tell you the ninjutsu for the three chakra natures of wind, fire, and lightning. Do not call upon me again."

As if she wanted to punish him, Kaguya directly stuffed an enormous amount of information into Gato's mind. Having abruptly received so much information, Gato immediately fainted.

During this process, Kaguya inevitably leaked a trace of her aura. But it lasted only an instant before vanishing again, so the tribulation clouds gathered as if they had been played for fools. After failing to find another target to attack for a long time, they dispersed once more.

It was dangerous to do this, but Kaguya inexplicably found it satisfying. Although Gato acted flattering toward her, no matter how she looked at him, she felt there was an unrestrained hint of mockery beneath it.

Kaguya was a woman, after all. When women were in a bad mood, everything looked strange to them.

Gato felt deeply wronged. He had been sincerely trying to curry favor with her, all right? But having fainted, he no longer had the strength to defend himself.

After waking up, Gato had no time to complain. He completely immersed himself in an ocean of knowledge.

"I remember someone once saying that learning makes me happy. Bullshit. Learning effortlessly is what makes me happy."

This kind of forced learning was painful at the very beginning, but compared to what he had gained, it was insignificant.

At that moment, Gato's mind had gained, out of nowhere, information on hundreds of wind-, fire-, and lightning-style ninjutsu of varying difficulty. This information included detailed descriptions of the ninjutsu, their uses, precautions, and training methods.

It was a terrifying number. Even taking Gato's capabilities into account, the difficulty of the ninjutsu Kaguya gave him would not be below C-rank. In terms of power, these were all advanced ninjutsu of B-rank or higher.

Ninjutsu ranks, from lowest to highest, were E, D, C, B, A, and S.

What did B-rank ninjutsu mean? B-rank ninjutsu was generally used by Jonin-level figures. Even an S-rank rogue ninja like Kakuzu mainly relied on B-rank ninjutsu for attack.

And Kakashi, the Copy Ninja said to have copied over a thousand ninjutsu, only had around a dozen commonly used high-level ninjutsu.
