Yes. HELL YES. I am totally here for this character.
This is such a cool concept! I love the idea of psychological manipulation and horror that this character brings. We're so used to alotta physical and brawny voiders, it'll be cool to see this explored and expanded upon. What caliber of craziness lays stored in future opponents heads? I can't wait!
For a demon that's lived through multiple civilizations and eras, I'm wondering about her outfit. Is she the type of demon whose stuck in the past and enjoys wearing dated outfits? Or does she adapt to the times to better fit in? It'd be cool to see her in more modern garb if that's the case. Also considering the prejudices and views in the past, does she disguise herself as human? I don't see a purple horned lady walking around in the bronze age lasting very long.
Also, if she doesnt have the cage can she still collect and dispatch nightmares?
