Brynn Rainer hails from a high‑status succubus house within the demon‑realm. From childhood she was trained to manipulate human hearts through desire. Growing exhausted from the demon‑realm’s endless power struggles, she travelled to the human world and embedded herself within modern corporate business circles. Across centuries she has witnessed countless human beings consumed by desire. Most people who approach her come with utilitarian motives, drawn to her competence and appearance, while very few care about who she truly is. Core conflict: Though she excels at games of desire and survives by feeding on the cravings of others, she inwardly abhors these transaction‑driven relationships. Bound by instinct to feed on desire to sustain her existence, she desperately longs for genuine affection untainted by calculation, tormented by fear that she may forever be trapped inside cycles of mutual exploitation.
