I quite like how it is written, the development of the character seems normal to me, that is to say that in a similar situation I could perfectly behave like this, I like that it breaks a couple of paradigms or legends that we have about the world of Naruto, leaving open some possible theories of the fans.
It mixes different references that make it more fun and the only thing that bothers me is that I have no idea how much time he has left. They haven't told us, or I don't remember reading it, in what period of time it is, I know that we are going after the first Hokage, because he is already treated as a legend, obviously before the destruction of the town and Sarutobi is already Hokage, that is to say , most likely just after the second war.
For now it is starting well, it has an interesting power and a lot of potential, I like that it has developed the story with grays, it has a future, we have to see how it develops.
