Review Detail of Cuerti in Haki User in Naruto

the novel is excellent, I did not find anything bad, I do not know why it has such a low score, there are many animes, manga, novels in which the protagonist has non-human women as wives such as beasts, dragons, phoenixes and more. That the protagonist has some snakes as a wife I don't see anything bad (the snakes are from the cave of the snake sage, the ones that appear in Boruto, those are the wives of the protagonist, half human half snakes) read this novel that is excellent.
