In Naruto: Reborn with Talent

The second the seal gave in, even if only slightly, Kaguya instantly pounced on the weakness and desperately tried to get out.

She knew the seal would give in. Rei promised her and she fully believed in him but she just couldn't help it. It was stronger than her. Her desire to escape overwhelmed her and made her act irrationally when she saw the first crack in the seal.

Fortunately for her, the Moon, and the Earth, Rei designed his seals with such behavior in mind. When he was paying a visit to various jinchuuriki and bijuu before he created his own artificial ones, many of the bijuu tried to escape the second he widened the seal enough for him to come inside despite there being no chance of them to get through the small leeway he created in the seal.

Kaguya got out but she didn't have a body nor her power yet. Before she could even register where she was, however, Rei's seals pulled her consciousness towards the pre-arranged place.

Normally, she would be pulled towards Black Zetsu because he was her will personified but Rei's seals were closer and worked instantly.

Kaguya felt herself entering the body created for her and a deep sense of relief flooded her. A moment later, her chakra started leaking from the seal directly into her new body.

Knowing she couldn't dilly-dally, she quickly started to use her power to adjust the body wherever it felt uncomfortable for her. She was molding it as clay and fortunately, Izumi and Rei did a marvelous job creating a body for her. Kaguya found she didn't need to put much effort into it.

Normally, this would have been a full-time job, and even after she was freed, she would have needed a long time to adjust while being unable to use her full power because inhabiting a foreign body was just not that simple... but the one she was stuffed into was surprisingly comfortable.

Maybe she was even starting to like it more than her original body.

But maybe that was because this body was a gift from the descendant she liked most and a man to whom she willingly gave her heart.

More and more chakra flooded her body, straining its chakra pathways... which, she now realized, would have been an immense pain in the ass. If Black Zetsu really managed to manipulate someone into freeing her, she would have inhabited that person's body.

At least, that was the plan.

Now, however, Kaguya saw that it would have been a massive problem for her. If the chakra pathways were strained due to her chakra despite them being on the level of Rei, then no matter who Zetsu manipulated in the Elemental Nations, her chakra would blast that person's chakra system to smithereens. That would have limited her even more for a long time. Worse yet, she had no idea where to even start repairing such damage.

Kaguya mentally released a relieved sigh and silently thanked the heavens for putting her in Rei's path.

The chakra pathways of her new body were strained but they held. Widening and toughening to hold her immense chakra, transforming into a system that could accommodate her power. It was an intoxicating feeling for her. Never before, not even in her original body, could she hold the power the chakra fruit gave her. That's why she mostly limited and restrained it, forcing herself to keep a lid on it.

But now...

Now she would no longer need to feel stifled!

Turning her senses inward, Kaguya quickly found the reason. On her belly, a seal started to form. A filter and storage, Rei called it. She was very reluctant to have it put on herself when Rei first introduced the idea to her but now she couldn't feel happier. The seal was sucking the excess of her power her body couldn't currently handle where it would be stored until her chakra pathways adjusted.

According to Rei, it would take a few months but her body and chakra would get progressively stronger until the seal would no longer be required. All Rei wanted in exchange was permission to monitor her during the process.

Something about gathering important data or whatnot.

As if he wouldn't observe her anyway... She fully intended to get into bed and show him everything of herself anyway so giving him such an insignificant promise was fine by her.

Oddly enough, there was no resistance coming from her power. Kaguya first expected some kind of epic but irritating mental battle, some kind of struggle between her own mind and the corruption from the chakra fruit but nothing like that happened.

She didn't even need to use her senses to know the reason for that.

It was the topic of most of her evenings in the seal with Rei. On her back, there was another seal. This one disguised as a tattoo of a pure white rabbit with two blood-red Rinne-Sharingan sporting nine tomoes in each eye and ten tails blooming behind him. Kaguya had to admit the tattoo was amazing... well, she designed most of it when she was bored so of course, it was amazing!

Her initial feelings about it were simply soured by the fact the tattoo was hiding a seal. One that would be etched not in her flesh, but in her soul. The tattoo was just a physical reflection of it. Her back could be fully skinned but once her skin regrew, the tattoo would appear again.

This mark was a permanent one.

The seal hidden in the tattoo had a simple feature. It purged the corruption in her chakra.

Not kept from influencing her but purged. A small difference in wording but one that meant so much...

Rei told her there was no way the corruption could ever be stopped. It was a part of the chakra fruit and it is now a part of her. But there was apparently no reason why it couldn't be turned into a benefit.

Sometimes, Kaguya really marveled at how Rei's mind worked. All she could think of was wishing to get rid of it the second she learned what it did to her mind while Rei was trying to figure out how to make the best use of it.

Kaguya had no idea about all its features though. That was supposed to be a secret for when she got out of the seal, much to her long-time chagrin.

Her power was finally fully out of the seal and settled in her body when Kaguya was harshly pulled out of her thoughts with a snap. Not a physical but spiritual one. The connection between her and the Moon Prison irrevocably shattered, bringing untold joy and elation to her.

She wanted to jump from happiness but instead, her eyes found the exhausted Rei softly smiling at her and her heart melted. With a massive smile on her lips, Kaguya jumped towards him and swept him into a tight hug, uncaring that she was naked and he was sweaty.

"Thank you!" She whispered, her voice cracking with intense emotion as she buried her head into the crook of his neck, and tears started to stream out of her eyes, down his shoulder.

A tired smile appeared on Rei's lips as he soothingly patted Kaguya and thanked Sage that Izumi left a half-hour ago because she was tired. It would have been embarrassing for his manly ego to let her witness this scene.

While Kaguya was embracing him, Rei also decided to scan her body, to make sure everything was working as it should.

Her power settled nicely, corruption was nullified and the soul seal on her back worked perfectly, the one on her stomach was filtering as it should and Kaguya possessed only two eyes, instead of her original three.

'Wait, what?' Rei's mind suddenly stopped as he gently rescanned her forehead just to make sure.

Feeling it, Kaguya finally pulled away from the embrace and rubbed her puffy eyes, not the Lavender pupil-less Byakugan eyes but three-ringed crimson-red ones with three tomoes on every ring, while sniffling. She looked Rei straight in the eyes and gave him a big watery smile full of emotions that was almost contagious as Rei found himself involuntarily smiling at her too, forgetting the issue of her eyes.

He counted on her correcting it by herself. He thought she would add that one eye by herself when adjusting the body but apparently, that didn't happen, and instead her 'normal' eyes gained Rinne-Sharingan.

It didn't matter. Not when such deep happiness and affection was plainly visible in these usually ruthless and frightening crimson eyes. Rei softly put his forehead on hers, content to just stare into those eyes while feeling her hands stiffly clutching on his waist.

They couldn't have physical contact with the seal so feeling her touch was a novelty. Rei circled his left hand around her waist, pulling her closer while putting his right hand on her cheek, rubbing it with his thumb.

Slowly, the distance between their lips shortened until they were softly touching. Kissing at first carefully before their confidence grew and their tongues started dancing with each other.

When they pulled away, Rei noticed Kaguya's chakra flowing into him, revitalizing him and soothing his tiredness. He grew a bit confused and wordlessly looked for the answer in her eyes only to be greeted with hungry desire and clear excitement.

Kaguya licked her lips and giddily whispered...

"Now.... let's have sex! I have waited long enough!"
