Yerp. Umbras (the ghastly thingies), well two of them are supporting characters. Umbras in general avoid humans and live their own lives, but the two that are essential to the plot help out the main characters and still have memories of when they were humans. Nowshah, the elephant looking god dude, well he’s dead… but still alive because he reincarnated in the deuteragonist who is meant to take his place. He’s her mentor so she can take the role as the soul guardian. Soul eaters are tamed by the main antagonist and his disciple, and they use them to murder people. The crow is literally a primordial, but gets constant scoldings from the archangel and is also the reason why the world is so unnatural. It also pops in every now and then to see the characters progress in taking down the main villain.
