Not a chapter
I created a backstory for why Narutos mom didn't know him. This A/N will explain that.
So I guess some of y'all got confused because Ameyuri is Narutos mom but she acted like she didn't know him.
This is because after Naruto started the academy the Mist had no more use of a mother figure for Naruto so they used memory suppression seals to make her forget him and for him to forget her.
This was so she could be his Genin sensei and not hold him back for later on in the story.
