Rei evenly stared at the black fox cub in front of him, getting an even stare from the fox in return before chuckling. Leaning forward, Rei took the cub into his hands and put it on his lap where the black fox cub curled into a ball and tiredly yawned before falling asleep.

'Little bastard,' Rei's eyebrow playfully twitched, 'Here he falls asleep when I have to keep myself awake. Damn was this tiring!' ​​

Rei slowly rolled his shoulders as his eyes started looking around, checking his wives.

Tsunade looked in wonder at her own blond fox that looked as excited to meet Tsunade. Rei smiled. The fox was definitely as excitable as Tsunade when she was surrounded by family.

Konan was highly amused as she patted her blue fox that almost preened at the attention by straightening her back and slightly lifting its muzzle. Rei could only subtly nod to himself. That reaction was definitely something Konan would subconsciously do every time he showered her with attention.

Mei was a bit lost, not knowing what to do when her auburn fox jumped into her lap and demanded attention. Honestly, Rei could instantly see the similarities between the fox and Mei.

Ringo had her crimson fox already in her hands, nuzzling it to her cheek. Rei could however plainly see the curious gleam in the eyes of both Ringo and the crimson fox as they subtly took the measure of their surroundings.

Lastly... Pakura. Her fox was green and both Pakura and the cub seemed almost hesitant to move from their spot as they eyed each other. Rei was about to look away when Pakura and the fox nodded at each other as if reaching some kind of understanding and then the fox slowly walked towards Pakura who started hesitantly rubbing its fur with a totally awkward expression.

Rei couldn't help but burst into laughter at that. It was the exact same expression Pakura had on her face when they had sex for the very first time.

Rei's sudden laughter broke the atmosphere around each pair of human and fox, causing ten pairs of eyes to redirect at Rei who tried to wave his hand to show he needed time in order to calm down.

"Sorry, sorry. It's just... Pakura was too cute there." Rei mischievously said which made Pakura flush crimson red and give him a slight glare. It didn't take her long to figure out what he meant by that.

Neither did it take long for the other women who threw Pakura knowing looks, causing her to groan while still subconsciously gently rubbing her fox.

'Yes... too cute.' Rei mentally decided, showing a proud smile.

"Let's stop teasing her, shall we?" Konan started speaking as she turned to Rei, "I would like to know how..." She waved her hand around her fox, "this actually works."

Rei slowly nodded, "Yes. It would probably be best if I explained what the foxes exactly are and how they came to be." He threw Tsunade a concerned look. It was ever-so-obvious the woman had a hard time pulling her gaze away from her fox and her body language... well.

"Your first concern would undoubtedly be your chakra reserves, right?" Rei asked, getting nods in return. "They feel full and yet, you have only ten percent in your body. Don't worry, that is normal. Your reserves will fully replenish," Rei smirked, "and the chakra in the fox will also quickly grow."

Hearing that, the women looked pensive before Konan again took the leading role and very carefully asked in a bit disbelieving tone, "You... are saying our reserves will more than double with this?"

She really couldn't believe it. When Konan heard about the term 'bijuu', she never thought it would be her chakra come alive. The problem with that was it was HER chakra. The second Konan's hand touched her fox, Konan knew she could still siphon chakra from the fox and freely use it for Jutsu.

Rei gave her a winning grin, "Nope." He quipped and gave a dramatic pause to let his wives accept the fact before he playfully continued, "They will increase by more than a hundred times. I really have no idea how much exactly the final number would be." He dropped the bomb, blowing the minds of his wives away.

Konan and Rei already had more chakra reserves than even Madara and Hashirama so getting such an increase was something the women really could not even imagine. After all, if Madara and Hashirama are the strongest according to their knowledge... what exactly are they becoming?

"To begin the explanation," Rei started, happy he had the full undivided attention of his wives, "let me give you a small briefing of what exactly Bijuu is. Shukaku, for example, is not made of sand as many would believe. He is actually the chakra in the sand and the seal markings on his skin. That's why it does not matter how many times you cut him in half. He would always simply reform. The concept on which the foxes are based is the same. They are beings made of your chakra." Rei stopped for a moment, letting that fact settle down.

"Now, I could not actually create a soul. After all, I do not own some miraculous eyes of circular bullshittery like the Sage of the Six Paths that could create anything with but a hand clap. Hence, you had to create a secondary consciousness and imbue it into the chakra during the creation process. In the process, this consciousness was strengthened, reshaped, and so on, and on... not important." Rei dismissively waved his hand, "What is important is that the foxes are part of you given sentience."

Hearing that, the women involuntarily smiled and cuddled their fox closer to them. It was almost instinctive. The only difference was Tsunade who held hers almost protectively.

Rei's lips stretched into an almost gleeful smirk before he continued. The next part was the reason why he could proudly proclaim himself a genius. "That means their chakra which is a mix of your own chakra, nature energy, and bijuu chakra they can now produce, is yours to use as you see fit. You can merge with the fox, boosting your reserves in both potency and capacity. Especially since the foxes do not have a limited body of flesh, hence their reserves can grow to insane proportions if we look at it from the perspective of human standards. While they have less chakra than Shukaku right now, with time, they will surpass nine-tails. Of that, I have no doubt." Rei explained, causing the women to look at the cute little foxes in a new light.

They were not just pets. The women quickly understood what Rei meant. These were tools that would help them grow stronger. And yet... Rei's wives knew that the bond they felt between themselves and their fox was not accidental. Rei clearly wanted them to treat the foxes with love.

"Once they grow up, you can use them as Summoning Animals you basically hold within you. And since they were made from your chakra and consciousness, they will never betray you. The best feeling for them is being merged with you, being at home. I also added a few seals on them," Rei winced saying that. The room they were in was a mess. Many seals were burned off, completely dispersed, basically destroyed. The seal matrix was unusable and Rei would have to invest half-year of effort to recreate it. Not that he would ever do something like this again. "thanks to these chakra manipulation seals, the foxes will be able to change their sizes at will. Any questions?"

The room descended into silence as all five women pondered if there was something they wanted to know about.

"How long till they grow up?" Mei eagerly asked.

"Few years... which means," Rei glanced at Tsunade, "you will have to separate." That obviously didn't go well with the women but Tsunade looked positively hurt. "They have to be in my Dimension in order for the nature energy to nourish them, boosting their growth and chakra reserves. Before you ask, yes, they could do it while merged with you but it would take centuries instead of years."

"Rei's dimension can be called one big energy battery." Konan nodded in understanding.

"Which means, they will need to be babysat." Rei smiled when Tsunade instantly perked up, "There are six of us so we will rotate on a daily basis while the seventh day we can take a break from work and spend in the Dimension together."

"I can delegate most of my work to one of my best apprentices and spend more time with the cubs." Tsunade interjected, causing the others to narrow their eyes at her. Only now did the other four women notice that something was off with her.

Rei's lips twitched at Tsunade's remark, "We all need some bonding time with them," Tsunade lowered her head. "But fine. If you can delegate your work, do so. Just... don't let me down by slacking. After all, it was you who wanted the position of the Head of Medics, Tsunade."

Tsunade looked mollified but also a bit hurt that Rei would consider her slacking. Looking at her blond fox... she couldn't in good conscience say she wouldn't do it though. Reluctantly, she nodded and decided for herself that she will teach more medics to show her dedication to Rei while also creating more free time for her to spend with her cub.

"Also, I have to say I am sorry, Tsunade." Rei sheepishly added, causing the women to turn to him with interest springing up on their face, before turning to Konan, "If you remember, when Tsunade bonded to us, her soul was fractured."

Konan smiled, "And this was a way to rectify that, wasn't it?" She then smirked at Tsunade, "But I see there were some side-effects, heh?"

Rei could only sigh in exasperation.
