"Sol Bianca: The Legacy" is a six-episode OVA series set in a futuristic universe where humanity has colonized numerous planets across the galaxy. The story centers on the crew of the Sol Bianca, a highly advanced spaceship, as they navigate a dangerous and morally complex world of interstellar piracy, treasure hunting, and political intrigue.
