agree, btw do you think there's a chance that mito has the same personality as hinata because i'm affraid that kishi will use it as a set up for nh
Actually I just looked Mito Uzumaki up and it said her personality was "Very Calm and Collected with a dignfiyed air about her" she had a strong sense of duty towards her husband and the village.
So until otherwise, we know she was collected, stern, and devoted. She behaved more like a noble than her Husband thats for sure.
It is possible Kishi could troll us again and make Mito like Hinata in terms of attitude but again he could also do it like Sakura.
In some other sense he could have made Kushina shy and lack self esteem but he chose to build Kushina's personality and even notable childhood events like Sakura off of well Sakura.
The main difference is, the whole Sakura=Kushina thing works because well the personality, looks, and parallel childhood are definite, it does not mean anything canon wise but it can support an idea of a possible relation between Naruto and Sakura. It could mean nothing in the end but for now, it supports the idea.
We hardly know Kushina yet with the info we have, practically 90% of any info with her could be matched up with Sakura. Mito we have practially nothing about, unless this changes it could be for Sakura, Hinata, or rather anyone or no one at all. I'm rather okay leaving Mito out, we know who she was and her role, she is a background character, I mean yes Hashirama is important to the backstory but we know more about him from other characters rather than him himself. Mito could be unrelated in fact to everyone and just be her own character. All we can do is wait, but we can sepculate, if Hashirama is laid back like Naruto, it does not hurt to imagine that Mito could have been like Sakura with an attitude, we just need to wait until and if we see. Thats why we speculate, to predict and imagine, not rush to say confirmed or canon.
