Currently, in AniDB, we have:
Harlock Saga is prequel to Maetel Legend
Maetel Legend is sequel to Harlock Saga
But “Maetel Legend” is the very begining of the story: Emeraldas has not yet meet Harlock. And the cover also reads “Prequel to the bestselling Harlock Saga!”.
So I think is better to switch the relation in the other way, or to change it to something else.
