Spice & Wolf 2.0.
Yeah, we're going to learn more about economics.
Copypasta synopsis:
After a long and treacherous journey, our Hero finally arrives at the Dark Lady's castle only to find himself being asked for help. The Hero explains how the war that the demons have brought upon the humans have killed thousands and put more in misery. The queen of demons however argues that this war has made the human society band together as one and showed empirical evidence how it has increased population, increased production, boosted economy and improved society overall. Furthermore, she explains to the Hero that ending this war will result in a civil war that will produce more bloodshed than there ever was. The Hero, convinced that the only way to bring peace, relatively speaking, is to join forces with the Dark Lady, agrees to help with her plans!
But you can't really tell all that much from the first episode though.

the perfect blend of physics and biology.
I don't really know what else to say about it really.
The designs are very faithful to the light novel and not the Ishida Akira manga (which is strangely the 'official' manga adaptation of the LN). You'll notice this especially with Grand Fire Dragon Princess
in the OP; that's very much the LN design.
otherwise the VAs are pretty much what I had in mind. Same studio as Spice&Wolf after all.
maid sisters are going to be delicious
