Long ago all men from planet Eros were lost during a war.
Fortunately they left behind a large supply of sperm and life on their planet evolved in a female only civilisation.
But now, the stock of sperm is running out.
So Astra, the heir princess of Eros is sent into space to seek the precious fluid.
No explicit credits on who worked on the comic. Inside front cover: "Manga from Jerry Robinson".
* page 31: "Astra ... is Jerry's most extensive international COLLABORATION ..."
* page 32: "Astra began life as a theatrical musical" "never done a musical so as a coauthor, he turned to his friend singer/songwriter Sidra Cohn" "Until the play is produced, it seemed natural for Jerry to turn it into a comic book series, and he found wonderful Japanese collaborators in writer Ken-ichi Oishi and artist Shojin Tanaka."
