Total Recommendations: 2
Both Mecha shows about an Outer Space Empire/Federation trying to take over parts of the Earth. (JIOR as in Kakumeiki Valvrave, a neutral and republic state based in space.) Both the antagonists, L-Elf Karlstein(Kakumeiki Valvrave) and Slaine Troyard(Aldnoah.Zero) share some similar resemblances. Both are smart, elegant and cool-headed. The only dissimilarity in both is that the protagonist and antagonist from Kakumeiki Valvrave get along as buddies as the show progresses, which is the opposite in Aldnoah.Zero. P.S. Please take note that this recommendation is valid to the 2nd seasons of Kakumeiki Valvrave and Aldnoah.Zero respectively as well.
I just can't stop but think that Death Parade is somewhat identical to Casshern Sins. The ending gives me the Casshern Sins vibes, where the music has a kind of isolated melody. Also, both are made by the same studio, Madhouse. Both Death Parade and Casshern Sins are highly psychological and most of the show has an episodic feel to it. Though Death Parade moves on a stirring pace, Casshern Sins is a much more slower and prolonged series. If you enjoyed Death Parade there is a brief chance you may like Casshern Sins as well.
