I always found the lack of Mithra on Yagudo interspecie doujinshi disappointing. We would always see them with freaking Orcs, even though those were mainly the Elvaan's problem.
I suppose the artists had trouble relating to lanky and somewhat handsomely built birdies, over rancid-looking lumbering slobbery fatties.
That, or that ONE orc in Dynamis Beaucedine would go on to inspire the whole thing.
