I've watched all the current episodes release. [hider= SPOILER]The only draconic being I've seen so far is an actual dragon that was once a human...and somehow changed. Hopefully it'll be explained later on.[/hider]

I'm honestly kinda sad that the show hasn't shown very many demi-humans that don't look...human. All the maids, Demiurge, Sebas look very human while the supreme beings looked completely non-human aside from bipedal. (The few ones we've seen anyway)

But despite the lack of draconic character I can settle for a lizardman :3
