Mito looks for a man she can love in Hashirama. She thinks there is one there but it’s hard to look as she should with so much unsaid between them. She makes her own way, its not even unexpected- after all she was the main negotiator for the Senju in the first throws of peace- but she would like to think that he could walk beside her. And maybe that should start with her this time, someday she must forgive if not forget. That day comes when Hashirama comes back from the valley and leaves behind his second greatest folly as he sheers off his long, long, hair; the lasting banner of his pride (and it is pride, a blatant taunt that no one can even get close enough to touch it).
She finds then that this is a man she can grow old with. Not perfect but enough. And then she allows herself to turn to having children, now that she can trust that their father will not drive them to terrible glory is search of what he will never give. Even now Tobirama is an ache in her, a brother she never expected to find, and she seems to be ever more the only person that remembers him as a man, a good man, as those that knew him slip away from the village one by one. So Mito cultivates the pieces she has of him, the knowledge she collected from his ashes, the children that she teaches (and Tobirama would have adored Kagami, sometimes she think she can feel his delight in the boy).
Mito lets time wear down her sorrow and her pain; she in a princess of Uzushio, she knows what effect the ocean has if given space, and she lets time like the tide wear her grief smooth and polished. She endures and she grows, ever changing and always steady, she takes the world as it comes at her and never lets it see her bow beneath it (her mother told her once; you are a woman of Uzushio, cry all that salt-water tears in the sea but always wear waterproof makeup).
