Thoughts:
So it seems i accidentally saw this awhile ago, it was a new seiries at the time that i watched it and i wanted to see what it was about, like if it was going to go the incest route or not, so i watched the first ep and it turns out only 1 ep of it was made
it actually wasnt terrible (as far as fanservice anime goes), it wasnt good either

My main problem with it is that they have this magical flying cat named ninetails that is never explained or even mentioned as being magical, apparently this world just has these magical cats and keeping them as pets is just a totally normal thing
The cat doesnt do anything, its just their pet, but it was just really weird since everything else is like it takes place in the real world

So why is that cat there, is it a reference to another anime, does it have some significance here, i spent most of my time watching this trying to figure out the importance of the cat, if it had some symbolic meaning or if it was a metaphor for something
I was waiting for it to start talking and/or to turn into a naked girl for the main character, but no, its just a cat that happens to fly
It made me wonder what other magical powers it has and if its sentient but just cant talk, or possibly chooses not to talk

My theory is that ninetails is an alien that was sent on a recon mission with another of its kind to find out how well defended earth was, they observed our species and ninetails became attracted to little female humans and his partner wanted to return to their planet to tell their council of leaders that earth was easy to conquer, but ninetails didnt want to hurt the little girls of earth so he killed his partner, landed on earth, and found a family that had a bunch of little girls for him to snuggle with and that didnt ask too many questions
The family in the show had never seen a cat before so they just thought this is how cats normally are and didnt question his strange appearance or magical powers
So now he lives in peace with them and his race of magical cat like beings believe that earth destroyed their recon ship and are well defended so they wont send any more ships out there in fear of retaliation from earth
