Diana

Diana hails from the prestigious Blackbell Earl family of London, where she was born as the youngest child. After her entire family was tragically wiped out, she forged a contract with the great demon Naberius as a means of survival. Despite her noble origins and seemingly delicate appearance, she possesses a fierce sense of honor and an unyielding spirit, refusing to bow before any authority. Sharing the bond of being fellow contractors with the heroine Vestaria, the two formed a deep friendship through their parallel circumstances, and Diana has shown unwavering resolve to protect those who journey alongside her.
