After the events of her night on the ferry, Emanon—the mysterious girl with a three-billion-year-old memory—continues her journey, drifting through life without a clear destination. Since the dawn of time, she has repeated the same cycle: leaving home and traveling the world as a teenager while contemplating her enigmatic existence, eventually meeting a man and giving birth to a daughter who inherits her memories and very being. Sasurai Emanon, narrated from Emanon’s own perspective, covers the period between 1967 and 1980, illustrating how her life came full circle from that evening on the ferry to her reunion with the man at the train station.
