The 1988 Movie & OVA are one of the best hidden gems in anime that were really hard to get until they were finally licensed in 2015 for North America. To be honest, I haven't watched this series myself and I created this guide...
I only included the animes I have watched from over these years. I'm not including Sequels from anime that started in previous years. I am including Sequels where it makes sense to keep watching, in order to complete the story.
