It was serialized in Tokuma Shoten's seinen manga magazine Monthly Comic Ryū from September 2006 to January 2008, with its chapters collected in a single wideban volume.

The series follows the travels of Emanon (エマノン) ("No Name" backwards), a mysterious young woman who possesses a three-billion-year-old memory, dating back to the creation of life.

[18] Writing for Otaku USA, Jason Thompson made a positive review of Emanon: Memories of Emanon, recommending the volume and commenting: "Beautiful artwork, philosophical sci-fi discussions, and atmospheric wordless sequences make up this tale of life as ferryboat ride.

Gaffney also praised the dialogues and Tsuruta's artwork, concluding: "If you're looking for something introspective and thought-provoking, this is a very good title to pick up.

"[20] In a more negative review, Demelza of Anime UK News criticized the story and characters, calling them "bland" and with no personality.
