Answer (Not a chapter)
Hello, this is not a chapter but an explanation to a question most people are asking.
Q. How the fuck does Danzo have kotoamatsukami, when Shisui is alive?
Ans:
It's a broad way of thinking in my part and digging up what the mangekyo sharingans are.
Yes, it might be weird for many fans, as they only focus on the main story line and one generation of Uchihas.
There are comments saying, All mangekyos are different!
And yes, they are, but only in shape! The mangekyo sharingan's abilities are mostly derived from the names of Shinto Gods!
So it can also be assumed there are enough mangekyo ability as there are names of shinto gods.
It's also not true that the same mangekyo ability doesn't appear on two people. It occurs. Not frequently but it still happens. Might occur due to similar experience and genes.
Then I would like to say, was Shisui, some ninja jesus who didn't have ancestors? His ancestor kagami was a famous ninja too. And he wasn't even of the older generations.
The uchiha clan has existed for hundreds of years. And it is very presumptuous of us to believe there was no other Kotoamatsukami.
Mind you, nowhere it is said that Shisui was the only Kotoamatsukami user in existence!
Many uchihas before the current generation has awakened mangekyo, or can be believed to have, as the previous generations had seen more wars. Many might not have met the requirements to use their mangekyo but it is really a narrow-minded way of thinking that there was no other kotoamatsukami.
And face it, it makes a lot of sense, that danzo had the ability before. Because he had manipulated people he shouldn't be able to with stupid schemes such as attacking ninjas at the border with other villages outfit.
Also! It is said that with Hashirama's cells it's possible to recharge a kotoamatsukami much faster. Not shisui fast as he only needed chakra consumption. But not the crow itachi slow either.
Sigh! Sorry for the rant but I think this was a very frequently asked question and needed an answer in this format.
And even after the broader way of thinking, if it seems implausible then just take it as the parody playing a joke on the story…
I am trying hard to keep the story logical and have received a lot of support for it. Please don't let this detail discourage you from reading the story further.
Thank you for reading this rant.
And I will upload a chapter as soon as I can take rest...
