Naruto: After I Died, I Seemed to Be Alive Again

She has no name. So for the first many years, she didn't know what the name meant. No one can see her. Of course no one would call her. She once followed Senju Tobirama and watched him create ninjutsu, become Hokage, and die. Later, she wandered alone in Konoha for many years, watching generations of people being born, growing up, falling in love, fighting, and then dying. She thought she would look like this forever. Until one day, she opened her eyes in the body of a dying boy. No. To be precise—— She failed to open her eyes. Because his eyes are gone. Strange memories followed. Uchiha. Kaleidoscope. And this young man's last wish to stay in this world. From that day on, someone was finally able to see her. They called her - Stop water. She also learned to look back. She didn't know it at that time. In the years to come, she would hear many different names. And every time, she would look back.
