Nobody talks about this one. A 1994 OVA that treats its demon resurrection plot like a real stakes problem instead of a backdrop, the seal on Uongadis doesn't just break, it matters to every character it touches. Adeu and his crew spend 13 episodes learning that stopping evil once doesn't mean you've won anything, just that you've bought time. The mecha designs carry weight because they're tools for a war that's already been lost once before. It's built for people who want adventure that doesn't pretend a seal and a sword solve the world's actual problems.

Long ago, a war between the forces of light and darkness ended with the evil Lord Uongadis sealed beneath an enormous monument known as the Earth Blade. Twenty years after that conflict, his demon followers are working to bring their master back, and the danger of his return is greater than ever. The story is a fantasy adventure OVA in thirteen episodes, with mecha action alongside its tale of an ancient evil threatening to rise again.
