The OVAs, collectively known as Rumic World, were released beginning in the mid 1980s with Firetripper. They were followed by Maris the Chojo, Laughing Target, Mermaid Forest, One Pound Gospel and Mermaid Scar. (These final three OVAs are dealt with at our sister sites Mermaid's Flesh and The Ring and the Rosary).
All of these series were released in America on VHS in the 1990s but have long since fallen out of circulation. Currently none of these series are available on DVD on either side of the Pacific.
