Classic Sunrise's dab into medieval mecha. Although there's obviously the futuristic mecha aspects, both shows also have some weird elements of sci-fi mixed in with its fantasy as well (moreso with Galient). You've got Dunbine directed by Tomino (Gundam) and Galient by Ryosuke Takahashi (Votoms), so they have their differences but if you like 80's mecha these are both definitely worth checking out.
