To start off with, the story isn't bad, in fact its much better than many other stories on this website, however, I don't really feel any sort of excitment. In regards to Writing Quality, the author does a fine job at presenting a work that is readable and makes sense, at least in regards to sentece structure. Stabilty of Updates, as of now, there is a consistent upload, so easy 5. However towards story developement and chacter design is where I find some problems with. When the MC interacts with those of his age, I can forgive that, since those interactions are with children. However, its where the MC speaks with adults is where I find a problem. I mention this in a chapter, but when the MC has a conversation with Mito, it was forced and unrealistic, Ninja wouldn't trust the words of a youngling, nor would they allow the MC to be alive when knowing crucial content. Also, there is no development towards the character's relations with others. Tsunade, for example, taught the MC, but aside from some simple thoughts, there is no real connection. Its similar to Mito's method, where the MC as a favor of Tsunade/Mito, they resist at first, but then agree anyway, for no real reason. It should be the MC trying to curry favor of the two, by being near them and interacting with them. Tsunade wouldn't pick a random kid who shows up to ask to be taught, and Mito wouldn't let the MC live after knowing S ranked secrets. The MC's relationship with Minato, is a bit more developed, but still has flaws of how quick their relationship progressed. In regards to World Background, there is some inconsistencies, but the Author has stated that he is aware of them is decided from more of an AU, so that is fine, to a degree at least. Overall, since this is the Author's first story, the story isn't that bad, but there has yet to be something that set's it apart from other stories. I would sugest taking some time to think of how the MC interacts with others and that while speeding the story up is certainly fine to skip boring parts, doing that too often and leaving out the interactions just makes it your average story. As a final note to the author, while I am critiquing your story, I know that you will do better overtime, and I am leaving this review to help you in improving on your writing, as opposed to the other reviews that really don't say all that much.
