Hinata suddenly find herself alone in a long-abandoned village at the depth of the night. She didn't remember how she got there nor how she managed to regain control of herself. Her rejuvenated young body had been used by Kaguya for so long that she had lost track of time.
Suddenly, Hinata heard Kaguya's voice reaching out to her.
"Like what I have done to your body? Don't worry, you will love what I am about to do to you next!"
Immediately, Hinata felt a sharp pain coming from her chest. She held her arms to torso as she tried to endure. However, the pain intensified and was quickly spreading to her entire body.
"What's happening to me?" She asked.
"I think you already know, I am making you into my new vessel. Now, stop struggling and behave!" Kaguya's voice shouted.
As soon as Kaguya's voice had done talking, the pain multiplies in intensity as a massive amount of chakra was unleashed from within her body. Hinata, unable to resist, began to scream as power surged through her body, transforming her.
"I thought about turning you into the new 'me', but that might end with those two sealing me away again. So, after much deliberation, Black Zetsu and I had decided to make you into something that will one day become even more powerful than me." Kaguya's voice explained.
"No! I refuse!" Hinata yelled.
However, her cried went unheard as her skin was dyed white. Her hair grew in volume as they too become as pale as snow. Kaguya's memories and thoughts appeared in her mind once more. However, instead of overpowering her own, this time, it was merging with her own, warping her own perceptions. Hinata, unable to stop this process, unwillingly absorbed all of it and thus fully inherited Kaguya's ambition. The pain was no longer bothering her, all her cared about now was obtaining even more power.
As the transformation process drew to a close, Hinata opened her eyes an examine her new physic with great satisfaction. She had indeed turned into a new Ōtsutsuki, seemingly becoming a hybrid between herself and Kaguya. She was taller and far more powerful than she had ever been.
"So, this is the new me. Very good, but I shawl make it even better." Hinata declared as she embraced Kaguya's personality.
With Kaguya's knowledge, Hinata suppressed the vast amount of chakra within her and reverted back into her human form. She then used a tiny amount to make her human body stronger and even more beautiful. With a white Kama installed on her back, Hinata can now transform into an Ōtsutsuki at will. She now had a new goal, to become an Ōtsutsuki even more powerful than Kaguya and to take over the ninja world from within. But to do that, she would need more power, even more than she had now. Of course, the best and easiest way to do that would be to steal powers from her husband Naruto, and she knew exactly which outfit she should wear to seduce him.
