As an orphan, Kii was trained to become a Vedeta since the youngest age. The only thing she knows about her parents is that they were Couriers and as such she comes from the northern, mountainous regions of Yorevale. She also knows her parents were killed by the kingdom militia, though the circumstances are unknown.
Having finished her training in the House of the Moon, she found herself in Trevenoux, where she became its ruler’s concubine. As a member of the elite, she was actively doing what she could to help her people in the north. However, some time ago she had to leave the city under mysterious circumstances.
