A crew of space pirates discovers Earth, a ghost planet nobody remembers exists, and everything they thought about human history shatters in six episodes. The show builds its world through character moments, not exposition, giving you a found family that actually feels earned rather than assembled. The sci-fi romance here is patient and atmospheric, letting mystery breathe instead of rushing to explain itself. Mayo's search for her parents becomes the thread that unravels the show's real secret: that forgetting home is the cruelest thing a civilization can do to itself.

Humanity has spread across the galaxy for millennia, leaving Earth forgotten in the dust of history. A crew of female pirates flies the Sol Bianca, an enormous starship, through one corner of this far-future galaxy. When a young girl named Mayo sneaks aboard their vessel, the crew gets an unexpected surprise. Setting out to learn where Mayo's parents are, the pirates head for Earth, hoping to uncover the secrets of the planet humanity left behind. The six-episode OVA mixes space adventure with mecha and science fiction.
