I just wanted to point out a flaw in the games’ philosophical logic and that is a
Kitsune have as many as nine tails. Generally, a greater number of tails indicates an older and more powerful Kitsune; in fact, some folktales say that a fox will only grow additional tails after it has lived 100 years.
Note: [T]hat/the (kitsune)/individual is described as being of in mid-early twenties.
However,
10 Obito Uchiha, The Ten Tails Jinchuuriki & Pawn Of Madara
Becoming the first Ten-tails Jinchūriki since Hagoromo Otsutsuki, Obito gained powers greater than that of the beast itself. He became strong enough to take on and defeat the entire shinobi alliance by himself.
This is partially supported by the fact that a Jinchūriki is of Japanese folklore, and the fact that a Kitsune gains more tails the older and wiser it gets, every 1000 years, it will advance a level of intellect and after that increment that amount by 10,000 years which is supported by the anti-life/life equation in Marvel, I noticed that the nine trials of hell was a multiverse based concept so hypothetically it should connect to the games story despite having no direct correlation.
A 12th level intellect is a term that was used to describe some of the smartest people in the universe. Metron claimed that only a 12th level intellect could have the slightest hope of solving the Anti-Life Equation and survive.
13th level intellect or greater
“Anyone more intelligent than this would have been considered super intelligent by Coluan standards. Few people were this intelligent. One that claimed to be smarter than this was Grax; who claimed to be a 20th Level Intellect.“
This also means that due to a kitsunes amount of tails being influenced by the IQ and age that it would be possible as to have a tenth tail as stated/ref’d earlier, and in some cultures 10,000 years is considered as being an eternity and being eligible of an assistant to a god.
It would be appreciated if you could add more tails than 9.
