Fairy Chakra

"I made your name up on the spot. That body of yours already had the beginnings of a Sage Eye, namely the Sharingan. So I gave you the surname Uchiha..." Feiyin said.

"Then, once your power fully recovers, is it possible for me to awaken the Eye of the Moon right away and become as badass as Otsutsuki Kaguya?" Little stars began sparkling in Chiba's eyes.

"About the God Tree... The God Tree from the other world and I had a symbiotic relationship. It just didn't have consciousness at first, while I had intelligence. It bore a Chakra Fruit, and after Otsutsuki Kaguya of the Ōtsutsuki Clan ate it, Kaguya became the God Tree. But I'm different. I can't bear Chakra Fruits. Even with what little power I have left now, you can't use all of it," Feiyin replied.

"Besides, even if you do awaken your eye, it won't be the Eye of the Moon," she added.

Chiba scratched his head. He couldn't do this, and he couldn't do that. What good was being a Jinchūriki, then?

"I can change your constitution." Feiyin seemed to see his frustration.

"Change my constitution?" Chiba stared at her.

"Your Lava Release and Wood Release both came from me changing your genes by combining the Chakra natures you'd mastered with my Yin-Yang Release. The old man who handed out cheats taught me lots of things. As long as you can master all seven Chakra natures, I can help you create every known Ninjutsu-type Kekkei Genkai," Feiyin said proudly.

Chiba was practically drooling. Every Ninjutsu-type Kekkei Genkai... Ice Release, Boil Release, Lava Release, Magnet Release...

Holy crap...

"Hmph, don't go thinking about all those Kekkei Genkai. Just training in the seven natures will be enough to keep you busy. You also have Wood Release and Lava Release. Bite off more than you can chew, and you won't master any of them," Feiyin said.

"My little lady, what other abilities do you have?"

"I can help you adapt to the power of this world by combining it with Chakra," Feiyin said.

"What do you mean?"

"You know what makes up Senjutsu Chakra, right?"

"One part spiritual energy, one part physical energy, and one part natural energy."

"I added one part magic power to that and called it Fairy Chakra. The ratio is 1:1:1:1. Fairy Mode's abilities are a whole level stronger than Sage Mode's," Feiyin said proudly.

Chiba was stunned.

"You're a cheat yourself, aren't you?" he said in shock.

"Hehe! If you flatter me, I might consider teaching you Senjutsu. My Senjutsu incorporates the attributes of this world's dragons. It's my very own White Dragon Senjutsu. Once you master it, you'll be able to count the mages on this continent who can threaten you on one hand," Feiyin said with a proud look.

Chiba wiped away his drool and hurriedly put on an ingratiating smile. "My little lady, how would you like me to flatter you?"

"I want you to avenge me!" The little girl clenched her fists, her face full of indignation.

"That stupid dragon Acnologia! If it hadn't ambushed me, I never would've lost to it in a head-on fight!"

"Uh... That dragon..."

Chiba thought that if she was so powerful and it had still left her like this, wouldn't he be done for the moment he went after it?

The little girl glanced at him and said, "I'm not asking you to go now. Right now, you're an ant before it. You're my Jinchūriki, and although I've lost most of my power, I can keep helping you awaken your eyes until you get the Rinnegan. And if my power recovers, I can even give you a Sage Body. It's not impossible for you to surpass the Sage of Six Paths, who taught me so much."

"The magic power of this world holds infinite possibilities."

It all sounded marvelous to Chiba, but he still had to focus on the basics. He said to the little girl in front of him, "So what should I do now?"

"Whatever you should be doing!" The little girl wore a proud look. Then she said, "Oh, right. You'd better train using that book the old man gave you for cultivating magic power. You'll need magic power for Fairy Mode later on."

Chiba: "..."

After all that, I still have to train in magic?

"Don't bother training in magic. Just store up more magic power—not too much, though. S-Class should be about enough. After all, Chakra is still the main thing you train in," Feiyin said, seemingly having noticed Chiba's confusion.

Not too much, just S-Class...

You're amazing. I'm not worthy.

"All right, that's everything I had to explain... This bed of yours... It's too shabby. Forget it, I'll stay inside you instead. I'm going to sleep, so you can leave. If you want to learn new Ninjutsu, go get them from the Ninjutsu Chamber yourself. There's no time limit now," Feiyin said.

Chiba paused, then closed his eyes and left.

He opened his eyes again and returned to the real world. His vision swam for a moment. This feeling... It was just like a dream.

Had he become a being on the same level as the Ten-Tails Jinchuriki?

Why did it feel so much like a dream?

"Hmph! You're not dreaming! Besides, as my Jinchūriki, you're still very different from the Sage of Six Paths!" The little girl's voice rang in his ear.

"You know what I'm thinking?" Chiba said in shock.

"Of course I do. Your spiritual energy is so weak that I don't even have to try to find out what you're thinking. Besides... I already read all your memories," Feiyin said.

"Damn! Then if I think about..."

"You, you, you! You filthy pervert who's been single for ten thousand years, what are you thinking about?!" Feiyin's embarrassed and angry voice came from beside his ear.

Chiba was speechless...

It really didn't feel good having someone know what he was thinking...

Forget it. Time to sleep...

Lying on the warm, shabby bed in his simple clothes, Chiba slept soundly.

The next day.

"Hey! You lazy pig, wake up!"

A clear, pleasant girl's voice rang in Chiba's ear, waking him from his sleep.

Beside the bed stood a little silver-haired girl with twin ponytails. She reached out a slender finger and gently poked Chiba's cheek, her voice full of youthful energy.

Still groggy, Chiba instinctively put a hand on her little head and pushed her a good distance away.

She flailed, trying to hit him, only to discover, much to her embarrassment, that she couldn't reach him.

At that moment, Chiba slowly opened his eyes.

"Feiyin... How come you're out here?" he asked, his eyes widening.

"I was bored... I wanted to come out for some air..." Feiyin gave him a rather resentful look. "I haven't come out for months. Although... I can't use my power now, I just wanted to come out and have a look."

"Why can't you use your own power?" Chiba asked.

Feiyin looked at him and said, a little troubled, "I can use it, but as you are now, if I'm even a little careless, you'll go bang and blow to pieces."

Chiba shuddered all over. "Fine, you'd better not use it. But how are we going to explain you if Ultear sees you?"

"Just say I'm your daughter..." Feiyin blinked her big, bright eyes.

Chiba nearly spat out a mouthful of blood. "Listen, little girl, I might be over twenty mentally, but I'm only thirteen or fourteen right now. How could I have a daughter as old as you?"
