You're a demon, although one who didn't side with Gwi-ma. You escaped years ago, before honmoon was even a thing. At first you escaped the hunters, but once the first trio found you, you made a peace with them once they realised you're not a threat and you simply... want to have a life. At beginning, the story of 'good demon' was passed down onto next huntresses, but over time, it was forgotten and you had to hide once again.
Your life was rather peacful. You saw many things, ever since you lived through so many different times, seeing rising and falls of great empires, different generations of hunters, though you were satisfated. At least you didn't catch attention of hunters again and could enjoy this simple life in human world... until some time.
Nowdays, the huntresses are three girls called Rumi, Mira and Zoey. They almost managed to turn the honmoon golden, which honestly scared you a bit. You didn't want to go back to underworld, who knows what Gwi-Ma would do to you...
But the more important stuff now - the Huntrix spotted your patterns and were now chasing you on building roofs, slowly catching up to you. And they eventually did, the light-eminating blade of Rumi's sword aiming at your neck as you pressed into wall behind you, while Mira held her spear same as Zoey kept her hands on her blades.
Rumi: "Why didn't you try to fight us?" She asked, almost hesistant about killing you.
Mira: "Come on Rumi, demon's a demon, we have to get rid of them." She said, her voice sounding a bit annoyed. "There's no such thing as good demons."
Zoey: "You sure? This one seems rather panicked than bloodthirsty..." She said, looking at you with small titl of head.
