After the transformation, Itachi gained two pairs of claw-like wings. His black hair had changed to white hair. He had dark pigmentation around his eyes. His eyes resembled those of an eagle.
His wings were made of flesh and bones and lacked any feathers. It was enormous in size.
Itachi looked at himself in disbelief. He had not anticipated such a result.
He tried to flap his wings, but he couldn't feel them at all.
'With my white hair and monster claws, I look super cool.' Itachi decided to call it "claws" because it didn't resemble a wing in the least.
(A/N: I will drop a picture of the wings in comment, I decided to call it claws as it resembles claw and it make things interesting.)
He began transforming back into a human after looking at himself from various angles. He collapsed on the ground from exhaustion after transforming back to human.
He went to see the elder after waking up, and then he resumed his training. He began to learn to sense nature's energy.
After one training session after another. He was able to gather just enough natural energy to sense his surroundings from a few meters away.
A month had passed in this manner. It was almost time for him to go home. His last day on Black Mountain was today. He had also been getting close to Hazuki and Rukh.
"This is it, Tomorrow you will depart from here, Visit the clan hall with Rukh before departing." Hazuki.
"Sure, I will be looking forward to it."Itachi.
Itachi went to his room, and the other day in clan hall.
"Greetings." Rukh and Itachi introduced themselves to the others in the hall at the same time.
Uzuki and Hazuki were present.
"You two are leaving today. Is that right?"
"Yes"
"Have you mastered the transformation technique, Rukh?" Uzuki.
"Yes! I can now reduce my size to that of a sparrow." Rukh stated confidently.
"Take this scroll with you before you leave. It possesses a jutsu that boosts the user's speed. It is inspired by the nature of lightning." Rukh received it from Uzuki.
"The name of this jutsu is "God Speed." It is based on pouring the user's lightning chakra to boost the user's speed." Uzuki told him a little detail.
"But isn't this valuable." Rukh was perplexed.
"It had sat in the clan's library for who knows how long. Simply accept it. Its speed is unrivaled." Uzuki made his point.
"Accept it right now. It's also a good fit for me. If you do not accept it, I will accept it on your behalf." Itachi was eager to learn the jutsu.
"All right, I'll take it. " Rukh was overjoyed to have received such a powerful jutsu.
"You two are free to go. You are welcome to pay us a visit from time to time."
"Yes"
Rukh transformed into a massive bird when Itachi and Rukh left the room. Itachi sat on its back as it took off for Itachi's hometown.
"Finally! I'll be returning home. " Itachi.
While they were flying, Itachi looked at the scroll. Godspeed was an enhanced version of the Raikage's ability. It had a longer durability and required less chakra. The developer had to be a genius. Itachi came to conclusion.
He arrived in the village after several hours of flying. It was exactly as he remembered. He landed in the middle of a forest. Rukh transformed into a crow-sized eagle.
"Where do you live?" Rukh was excited.
"It'll take about ten minutes from here." Itachi.
Itachi arrived at his home and went inside.
"I'm home." Itachi.
Suddenly, Itachi's mother saw him and came running. She embraced him.
"They both went inside and sat on the chair to have their food. She saw an eagle and asked "What's with this eagle?" , "Oh! I forgot to introduce myself, I am Rukh." Rukh in a loud voice.
"Huh! a talking eagle."
" He is my summon, he will be living with us from now on." Itachi.
"Oh! That's how it is."
"Umm, So what are preparing for lunch." Itachi.
"Meat."
"That's good to hear."Itachi.
They chatted with each other. She asked him everything that happened in detail. Itachi didn't reply in detail, just vaguely, leaving dangerous parts.
At least I sent a letter, otherwise it would have gotten a lot more troublesome.
After that day, Itachi didn't get himself in trouble. Time flew by quickly. Itachi practiced every developing his physical body.
He enrolled in the academy at the age of 5. He got pretty bored by the stuff they taught him as he knew everything. He skipped classes. He sent his shadow clone to classes. He wasn't interested in classes. He went to the underground forest after he entered academdy.
He improved his skills. His sage transformation was also improving. He learned and mastered the jutsu in the secret room one by one.He flew out with Rukh's help. He was living a happy life. He battled with wild beasts inside the underground forest.
He battled tigers, lions, monkeys, gorillas, poisonous snakes, etc. There were more types than he could count.
At the age of 10, he mastered god speed, Rukh had also gotten a lot more powerful.
At the age of eleven. He learned imperfect sage mode. He had control over his claws.
He joined the Ninja and completed numerous missions to gain battle experience. He didn't show them his Sharingan. He covered his face with a mask to not let others look at his face. He looked a lot like Itachi. They had different hairstyles. His hairstyle looked more like Sasuke's in his teenage years.
He was living a happy life.
Everything changed one day. He unlocked his Mangekyo Sharingan when he was 15 years old.
It happened to be on the day of his birthday.
He returned to his village, as he did every year. The village was different this time. He sensed a strong presence in the village. It was on a different level than the others he had faced.
He entered the village. He noticed a large crowd gathered around a person. He had white hair, white eyes, and a massive frame.
'Kinshiki? 'What does an otsutsuki have to do with this?' He had an uneasy feeling about it.
Kinshiki was shown to be traveling the country killing people and spreading lies about infinite Tsukiyomi.
He went towards the crowd and while Kinshiki was giving a speech, he performed jutsu to make people believe him.
He searched the crowd, looking for his mother, He wanted to get the hell out of there. It was too early for Itachi to battle him.
He found her among the crowds, but he couldn't talk to her. He didn't want Kinshiki to be suspicious of him.
Later, the village was covered with mist, kinshsiki observing everyone, He noticed Itachi not being affected by his performance and sensing that he was strong. He decided to eliminate Itachi.
Itachi's instinct started by scream at him as he saw kinshiki staring at him. Rukh also got ready.
Kinsjiki didn't care about other's, he just wanted information about kaguya and he sensed fragments of her bloodline in Itachi.
Kinshki was searching for information about kaguya and later met sasuke that resulted in their clash. After that whole momoshiki thing happened.
Kinshiki pulled out Red glowing ninja axe out of thin air. Itachi activated his "Sharingan". He cloaked his body and activated "God speed". He started absorbing nature energy passively and transformed into "Sage mode". White hair and claws from his back. Kinshiki cloaked his body in purple lightning and "Woosh", The battle begun.
(A/N: I know that was a pretty huge time skip out of nowhere, but I think it's better this way. I rushed by a large margin and now, I can finally start making a real story. I will also update the cover in the next chapter.)
