Qingu, the Visage of Radiance
The Visage created after the Fall. And that's what I've always admired about them, because they were able to reverse their nature and be reborn into something else. Naamah is one of those Devils.
Proud Bel appreciated the full potential of people, she spent time with them, she led them into battle, she changed herself to become a better warlord than she was before. Many siblings didn't appreciate the act, but she didn't care. She still doesn't care now. She has always sought support only in herself, and those around her are useful material or tools to transform the world according to her will.
That hasn't changed in the present day. After the Abyss, she entered the body of a young scientist from Germany. And even though the passions of her former body were not alien to her, she paved her way into politics. Both demonic and human. She is currently the Tyrant of a major city and a successful Faustian whose mortal work helps with faction issues.
She's pleased. She's as pleased with herself as ever.
