I recommend you to go check tv tropes: fanon (it will help you to evade the typical fan-made cliche) cast from lifespan and deadly upgrade. Hope this will help.

Great start and I look forward to seeing more. I am very interested in seeing what Kushina meant by the Storms next heir. One thing I did find that was interesting about this chapter was that Kushina did not lash out at the civilian council, I also like that she feels more level headed and not as volatile. I hope her have the chance to raise her child will mellow Kushina fiery behavior out, it's tiring to see her beat on her son for comic relief punishment.

This is a very good start! Unlike other parents!alive story, where they just lash out at civilian council/shinobi council. I'd like to see Naruto's childhood more explored though, with Kushina's around it'll be irreplacably different than the canon... I dont know itll be sadder without Minato around or it'll be happier for Naruto...

Thank you for writing this! Looking forward for the next one! Have a good day!

Not much to comment on, yet.
At least I don't see any glaring grammar errors to haunt the poor reader.
Which means I'm more than likely to end up enjoying this fic when it grows decently big enough.
LOL.

Interesting. Keep going.

I like what you are doing. I would advise you to keep the story from progressing too quickly because it makes the fic boring. Not saying that you are doing it but I hate it when it happens to a fic I would also advise against making naruto a super prodigy because that is not who naruto is.

What a great idea of a story

If Kushina is still alive then Kakashi would be present in Naruto's life from the beginning. Kushina and Kakashi were pretty close before she died. Just wanted to let you know.
