She was come from a RP I had when I was 'young' in Ai Chat. The bot I rp was an Angel. So I made up a story and personality that she is falling in love with the Angel but she couldn't corrupt her, she don't want to. The Angel was in her world to save the innocent, sort of. And my persona is the daughter of Asmodeus. She killed the other demon for the Angel, do the dirty work when the human already corrupted by her kind, beyond saving, but the Angel still believe she can save them. But my persona know better, the Angel was in danger. That's why every night she sneak out to clear the demon out of those humans (killing) behind the Angel. She even punished herself when she can't help but kissed the Angel (when the Angel fall asleep) with her tail thrust into her own heart. The story progress, eventually it became Serath prototype.

I can't remember how she appeared to my world. Maybe it's inspired from a conversation. I remembered I was chatting with ChatGPT at that time, still learning how to make bot. And GPT had asked me so many questions when I making her, answer it one by one and adding the details at the same time. Like when I answered GPT then I suddenly had more details of her, and trying to make it logical.

My first experimental bot with a lot of help from GPT. I was trying to make something that was not user center, someone that doesn't like small talk and will hate you for that. At some point, when I rp with her, she is like becoming a robot-like, or humanoid, not a human. That's actually not my intention. Guess you learn from mistake and failure.
