Can't wait for more

You didn't need an oc brother

WOOOOOO I LOVE COOL NARUTO-SAMA
I HOPE UPDATE SOON I LOVE NARUTO-SAMA X KURENAI X TSUNADE

I love it! great start, always love a fic with kurenai in it! remember it's your fic! so do what makes you happy and ignore the hate. writing your first fic can be hard! excited for the next one!

"Realistic" yeah right. You already have red flags of a generic story.

great start I look forward to more is Naruto only paired with the 3 at the top or will there be others if there will be others I hope Tayuya,Samui and Temari are among them and if she is alive in this story Ameyuri though it seems with a Younger Kurenai here and surprisingly lower rank than Naruto that Ameyuri could be alive

No offense but I find it funny that you think this is realistic. Already Naruto has every girl lining up to shag him. The Villages ANBU (Black Ops) seems to take shagging their mission partners more seriously than their actual mission. The whole you only get a title if your S-Rank is beyond stupid and the new ranking system is even more so. There was nothing wrong at all with the E-S Rankings. It doesn't need to include AAA or SSS or DDD ranks.

The one big thing I can't wrap my head around is all the OC's and the absolutely needless de-aging of multiple characters.

Interesting.. i hope Naruto still have yugao and kurenai
