I was reincarnated as Kaguya Ōtsutsuki

With the vermilion-colored Chakra Fruit in her hand, she walked towards the four at a slow pace.

"You've beaten him." Hashirama stated the obvious, raising his thumb in victory.

"It was amazing, I was so paralyzed when you approached, Kaguya Baa—chan!" Naruto seemed recovered and full of energy.

Instead, Sasuke stared at her with a frown, distrusting her.

She didn't really care what that boy thought of her, as long as she didn't give them reasons to confront her, there was no problem, and even in the event that they turned against her, she would finish them all off without scruples.

Delta walked up to her and clung to her like a Koala. She had no choice but to pet his head with an amused smile.

"What's in your hand?" Sasuke asked. He had tried to find out with his Sharingan, but other than a massive amount of Chakra inside, he found nothing.

"It's Isshiki," I replied calmly. I then ate the fruit in front of them, not caring what they thought.

"Huh?! He ate it?" Naruto seemed surprised that he ate Isshiki.

"This is the Ōtsutsuki Clan's way of doing things, don't be surprised," I replied.

After absorbing Isshiki, her chakra and longevity increased. Her body also became lighter. An eye also opened on the palm of her right hand, though it did not enhance her field of vision.

His Rinne-Sharingan on his forehead also underwent changes, turning golden, like Momoshiki's.

"We absorb our comrades to increase our powers or we absorb entire worlds." I finished my explanation. "Though I no longer have any interest in the second alternative," I clarified.

"Your goal was always to find and absorb Isshiki," Sasuke chided him.

"Isshiki also planned to destroy the world. I accomplished my goal and we saved the world, I don't see the downside to that?" I replied confused by his recrimination.

"What are you planning to do with that much power?" Sasuke asked.

"Hey, Sasuke, I think you're going too far," Naruto said, trying to stop him. Kaguya had only helped them since she escaped from her seal.

"No. You're right. I've kept information that I should have shared with you." I stopped Naruto and looked at Sasuke.

"Over a thousand years ago, five Ōtsutsuki were sent to this galaxy to collect and consume the Chakra Fruits. With Isshiki's death, there are only four of us left."

Sasuke widened his eyes in surprise when he found out that there were still three Ōtsutsuki left somewhere besides Kaguya.

"The remaining three are named Momoshiki, Kinshiki, and Urashiki. Of the three, the most dangerous of them is undoubtedly Momoshiki, who is far more powerful than Isshiki and even me."

"More powerful than you?" Naruto asked in surprise.

"So many worlds have they destroyed to gain so much power?" Hashirama asked, clenching his fists.

I nodded at his question "Momoshiki is no longer more powerful than my current self, not after absorbing Isshiki." I didn't reveal Shibai Ōtsutsuki's absorption, that was information I would keep to myself.

Everyone sighed silently. "But they know of the existence of a world inhabited by people with the ability to use Chakra, and that is a temptation they will not ignore. They will soon arrive and attempt to harvest the Chakra Fruit." I warned them.

"Then you will absorb them and increase your power again." Sasuke scolded again.

"Yes," I replied, not caring what he thought.

This world was my home now, and I wouldn't allow others to destroy it, and if along the way I can increase my power, why wouldn't I?

...

When everything calmed down, Sasuke opened a portal and returned to Konohagakure with Naruto and Hashirama, leaving Delta and Kaguya behind.

"Kaguya-sama, why have we returned to this place?" she asked, looking at the barren, lifeless planet around her. It was the planet that Kaguya had cut in half when she finished off Jigen.

"Follow me." She replied, taking flight with Delta following behind her.

On this planet, dimension, was trapped the Jūbi that Isshiki created and periodically drew Chakra from.

When she arrived at the place, she deactivated her Senringan as it was no longer needed and ignored the holographic artifact that showed the appearance of Isshiki, Momoshiki, Kinshiki, Urashiki and herself and stopped in front of the Jūbi.

The Jūbi desperately tried to devour her, but was unable to reach her.

Delta showed no surprise at the Jūbi, seemingly uninterested in any living creature other than Kaguya.

This Jūbi shares many similarities with its counterpart, though it is smaller in size.

It is a cyclops-like creature with a swollen, round body, with long spikes and protrusions growing out of its back at right angles. It has a single eye with four concentric circles and six tomoes on the first two circles. It also has a wide, cavernous mouth with square-shaped teeth, as well as a chin with a spike protruding from it. Its tails are pierced by black stakes, preventing it from moving.

"Delta, you are weak. You couldn't do anything against Jigen other than watch and warn." Delta lowered her head, believing that Kaguya was scolding her.

"I'm sorry, Kaguya-sama..." Delta replied with an apology.

Suddenly, she felt a hand on her head and saw Kaguya smiling at her.

"I will help you absorb the Jūbi and you will increase your power. Maybe you can become an Ōtsutsuki one day." I encouraged her.

Just like Isshiki encouraged Code to feed Kawaki or Boruto the Jūbi to grow the Shinju, consume the Chakra Fruit, and become a new Ōtsutsuki, Kaguya encouraged Delta to consume the Jūbi.

Delta becoming stronger would be a great help to her. Absorbing the Jūbi would also increase her longevity, allowing it to accompany her for many centuries.

Delta raised her head and nodded determinedly. If becoming the Jinchūriki of the Jūbi and transforming into a Semi-Ōtsutsuki helped Kaguya in any way, she would do it without a second thought.

With Kaguya's help, the Jūbi's Chakra entered Delta's body. Just like Madara and Obito Uchiha when they became Jinchūriki of the Jūbi in the Fourth Shinobi World War, Delta's appearance underwent great changes.

Her fair complexion became pale like that of an Ōtsutsuki, and in the center of her forehead, where the number 'Ⅰ' was tattooed, a third eye, the Rinne-Sharingan, opened. She also grew two protuberances in her yellowish-green hair, resembling Momoshiki's horns after he had consumed Kinshiki.

"How do you feel?" I asked Delta.

She simply clenched her fists in surprise, feeling the new power coursing through her body. She had obtained many abilities, and her Chakra reserves had also increased dozens of times.

"I feel better than ever..." she replied.

"It was to be expected." I commented on this.

If she already had an exotic appearance before, she was even more so now. I considered Delta to be one of the greatest beauties in this world, but now... Kaguya had to control her thoughts.
