In Naruto, at the beginning and for a very long time, we had no idea who Naruto's parents were. At first, I thought it was because they were unimportant nobodies, but not at all!
So, why didn't the Third Hokage tell Naruto who his parents were? Why didn't Kakashi tell him? Or Jiraiya?
I understand not telling him about being a receptacle, but why not tell him about his parents? And even after he discovers he is a receptacle, no one is telling him about his parents??? That truly doesn't make sense to me, and I even find it outrageous that they would hide such an important piece of information from him. They could have given him pictures of his parents all along and told him how his parents died (as heroes). But no, instead they hide it from him.
So, is there an in-universe explanation for this?
