THE BEST

So she helped free Obito from the rocks. Wonder how that will change the course of history :). Looking forward to your next update

Well that was cool

Love Mei's part

I love this chapter the most
Sister power
The awakening
Mei
Action!

Ok I love this turnaround

I love them even more

Oh my goodness. I love these girls.

Oh I really really enjoy this

THIS IS SO AWESOME AND AMAZING
THERE IS A SINCERE LACK OF MEI FICTION

Because of Mei's intervention, I really hope that Kakashi gets over himself. I hope that he's able to save both Rin and Obito this time. I don't want any of them to die, but then again, it is a war. Please continue this story!

I really like all the sister and hope they don't die...at least not all at once.

But question is, how far does Miwa remember of Naruto canon when she regains those memories and how detailed are those memories?

Though at least once she regains her memories she could use that in advantage to help her Shinobi career and become strong enough to not only help boost Kiri's strength but also with its economy from using knowledge of her original world (our world).

If Kakashi can graduate to genin at the age of 5, then I believe Miwa can become just as strong. Maybe not OP strong, but prodigy strong in her area of expertise.

I love this! The concept of this story is unique and interesting. For romantic pairings though, maybe much, much later in the future. I don't think any of the Terumi siblings would have time for romance, especially Mei.
Anyway, at first I thought Yui was going to be a bitch, but I'm glad that she isn't. I wish Miwa and her would be able to come up with a solution. As much as I wish Saburo dead, now isn't the time. His death would only cause more conflict. To be honest, I think Saburo dying by Mei's hand would be rather fitting. That's just my opinion though.
So yeah! Great job.
