Fiena

Fiena is one of the twin Demon Gods who dwells at the uppermost floor of the Tower of Baia, always acting in concert with her elder sister Veina. She wields formidable divine-realm skills and specializes in bow-based combat, executing coordinated attacks alongside her twin. Calm yet merciless by nature, the two sisters can merge into the far more powerful Demon God "Veirfiena" when driven into a critical situation, making Fiena a fearsome adversary that the protagonist Alina must overcome.
