"Sometimes I dream that I'm here with you, fighting with you, having fun like the old days, trying to hold onto old memories of the good old days, clinging onto survival. But whenever I awake, the two of you leave my side, back to the shadows. I dream you're still here, however, it's a dream, not reality."
Sasalis Oras always had trouble with having to keep up with time, constantly being frozen in time due to the side effects of her Kenkai Genkai.
She's seen it from the beginning to her current time, from Kaguya Otsutsuki to the Naruto Uzumaki, finding herself becoming only a person lost in time for what may be until the world is gone, or she could end up dying earlier than most, the thing was, she never knew. She can't kill herself, as it always stops by ice, freezing the weapon until it's too cold to touch, a living hell she can't escape until age catches up with her.
Sasalis freezes over time from the Fourth Hokage's time to the Third's time (Naruto Genin Time). Sasalis was quite happy to know someone from the past, without having to be awkward when they tried to guess her age, she had to write it down on her hand constantly so that when she would freeze she could keep track over her age when she was active.
The Third Hokage places her on Team Seven for the time being, informing Kakashi of his former teammates survival of the rock avalanche, although it becomes strange as Sasalis used to be annoying to him because she was a few months older, but now he was the older one and still couldn't stop her from hanging at his window, pranking him, all things that made Naruto look like an angel.
