So after I did "A Fairy and a Succubus" I felt like doing another Ethel related pic. It took me a little while to figure out where I would go with that and then after brainstorming, I came to the idea of Ethel, using her siren song, entrancing other Succubi. I almost made her "adoring audience" just generic Succubus extras, but then I thought it'd be fun if they were established characters. So I went with adding Albedo and Kurumu to the piece, both mindlessly chanting how Ethel's the best. Enjoy!
