His backstory is given from his perspective, a lot of it is left unrevealed and not very well explained. It might look like a full backstory, but the mc himself didn't understand half of what was happening around him at the time. He does realise that something is wrong eventually, he goes through a few changes and goes on a journey to find out more about his past. That backstory only gave the basic outline of events. Later, when he meets Netero, we also find out more about him. Like how he is prone to downplaying any relationship he has with anyone. I didn't create situations to show his qualities because he barely has any. I created situations to show his flaws, to point out things that he needs to work out on. And, later in the story, he begins to open up more to people around him. This is more the story of a flawed character growing to recognize his flaws, working on them and exploring the truth of his homeland.

creating a story is like an economy, it's based on supply but demand, but instead of money what it's exchange is all about the information. in this case sure the information come from the mc perspective or there is actually more information that not yet being told but it doesn't matter, because you are not yet created the situation where I as a reader demand all of those information that not yet being shown at early chapters and when the situation at early chapters that make me demanded the information happen, like when I curious or interest about your mysterious mc and want to know more about him, you oversupply it, like how you tell me in chapter 4 what the mc hatsu is or what kind relationship he has with netero or how exactly his hatsu actually worked or what kind of an occupation he has and many more. sir I don't needed to know all of this, sure all of this information might be been told by first POV but it's still an infodumb, where you just share all the unnecessary information that not being demanded by a reader, when you can just created a appropriate situation created a demand or interest to shown all of these information that representing the qualities of your mc, again "show don't tell" that's what I believe the best wat to tell the story and you are not doing that it's a problem, at least for me. and that's only the first problem that I have not yet the second one but might be we will be discuss it later about that one.

Mate, a lot of ppl cried about wanting to know more about the mc. I just gave a basic backstory(flashback format). His hatsu is barely touched upon and any other ability he may have is not mentioned at all. The Mc's profession is also not that important to the story and the mc as a character.

of course ppl want to know more, your mc is interesting so it's not surprising, and given the ppl the right amount of the information is the best way to story tell instead of oversupplying it. yeah sure it's might be a basic or barely touched information or like you said "not an important information", but still all that is unnecessary information that a reader at least for me doesn't need to know or there is no situation or scenario that exist yet on the story that make the reader demand or interest to know. that's why for me you are oversupplying it instead giving the right amount of information and that was a problem for me, that's all.

Author, a tip for info dump is to incorporate it into your story, divide or just explain what you have to and when you need to i understand people wanted to know more info about the protagonist but it would have been good if while the story was progressing slowly you gave the readers more info about the mc

Like a situation where he has a flashback of his past cause of an incident and such
