Chapter 1

On a comfortable bed, in a comfortable home, a certain black and white cat rested peacefully. This cat happened to be the most powerful being in existence, a Feline God that asserted its dominance by slaughter every other god since they would just disturb his naps. Now, it was his sole job to watch over the multiverse, though he only watched certain anime worlds for entertainment between naps sometimes. Once every few million years, give or take a few billion.

Now he grew bored. He had watched a plenty of fun adventures and wondered why he couldn't enjoy one himself. Of course, he loved his nap short naps, but he did want to experience something else in his life.

'Hmmm. I guess I'll just reset the timeline in the worlds I've seen and enjoy them myself? Yeah, that sound fun. Where to first though...? Eh, whatever, I'll figure it out after a short nap...' the cat thought to himself as he drifted off to sleep once again.

When he next awoke he had decided on his first adventure, he would go live in the world of shinobi's, known in some as Naruto.

'... But not before I make some changes to it.' He thought to himself as he stood up and quickly transformed into a human with cat ears and a tail. He had short swept back red hair, and sharp black eyes. His face made him appear rather handsome and at times mischievous, while his body appeared moderately fit; if anyone else was there though, they would be able to feel the sheer power emanating from it, since he didn't feel like hiding it. Not like anyone was here anyway. It was his own section of the universe he cordoned off for his napping needs.

Leisurely, he roamed into his kitchen where he grabbed a bottle of milk and began drinking it. "Alright, then I'm gonna need a background. Let's see... well, I'll just create a whole new clan in the Hidden Leaf. Nekotsume Clan, let's go with that. Cat ears and tails are normal, they can transform into cats, and they're the overall strongest clan in the Hidden Leaf. Most agile clan, everyone born may be a different feline regardless of parents, so there's a lot of variety. And to cement their strength, I guess, the Clan has a contract with feline summons that help them learn a different type of sage mode, if they're approved. That should be good enough, now I just make my family, and... done! Almost forgot, I can't let anyone enslave us cats, so I'll be Matatabi's jinchuriki. Damn, now I need to make more changes... I'll just pause this for now and come finish after my nap."

Several million years later the cat god finalized his changes to the Naruto world and transferred himself in.

Hidden Leaf Village, Nekotsume Clan Central Compound, 2 months before the Kyuubi attack.

"Congratulations, Matriarch! You have a beautiful little boy!"

"Nyah? Well, put him down quickly and get ready, here comes anyother one!!"

...

"Congratulations, Matriarch! You've delivered a beautiful little girl and a beautiful little boy! The future of our clan is bright!"

"Haah. Haah. Mara. I think we can both tell, I'm far too weak right now, and even though Matatabi wont try to break out, those bastard elders will try to pressure our clan, claiming that a weakened jinchuriki isn't fit to be a jinchuriki. Seriously, whoever told them about Matatabi has caused our Clan so much trouble. Those scum lust after our power to begin with, and with the knowledge that we have a tailed beast it's even more annoying.

That Danzo surely is ready to assassinate me for Matatabi. It's only a matter of time. There's only one way to avoid Danzo and the elders' schemes for Matatabi. Announce that my sister, Yoruichi Nekotsume is now head of the clan. Matatabi, I'll have to transfer you over to my son, since we're pressed for time. Mara, help Yoruichi lead the clan, assign Himari Nekotsume as my sons guard, tell my eldest daughter to look after her new siblings and tell my children I loved them. Lastly, their names. Karma Nekotsume for my son and Ailane Nekotsume for my daughter."

With her last words recited, Lin Nekotsume, Matriarch of the Nekotsume Clan, concentrated on her jutsu to transfer Matatabi safely into Karma With Matatabi's willingness, there were no dangers involved. Of course, this was all orchestrated by Karma himself, when he rewrote the world. Naturally, he could save his mother, but instead he decided to let it play out. When she died, he would simply resurrect her back in his home with the capabilities to watch over everything. He wanted the world to play out as if he wasn't a god. Most of the time. He naturally wouldn't limit himself for real, but he had to act like he was only a genius. He couldn't experience the world properly if he just swept it clear of any enemies from the start. At least he didn't think so.

After everything was settled and the aforementioned Mara fed him some milk he comfortably went to sleep thinking he should probably get rid of Danzo soon too.

Authors Note: Yeah, major characters of the clan will be catgirls from other anime, only with the Nekotsume surname. Also, some others will cross over from the worlds I took them from. Byakuya won't be going to those worlds, so crossing them over to other worlds seems pretty ok for me. The ones mentioned already, are Yoruichi Shihoin from "Bleach," Ailane from "SHOW BY ROCK!!" And Himari Noihara from "Omamori Himari." The mother is Lin Xiao-Mei from Shining Hearts! As for why the mc has a twin sister; the formation of a new team, among other things. MC face and hair looks like Karma Akabane from "Assassination Classroom." That's why I gave him the same name. He just doesn't look fragile, more like fit and tonned, but not super athletic.

Also there'll probably be other crossover characters. Also, I'll be using ninja and shinobi interchangeably depending on which one I think sound better in a given sentence.
