This single-episode OVA from 1996 closes out Lord of Lords Ryu Knight: Adeu's Legend and is counted as the 17th episode of that series. The earlier story is set two decades after an ancient war between light and darkness, which ended with the evil Lord Uongadis sealed beneath an enormous monument known as the Earth Blade, while demons now scheme to bring their master back. This final entry blends adventure, fantasy and mecha action as it brings that saga to its end.
