Reena is the Garlan Village Chief's daughter and Melfice's fiancee.
History
When rumbling began to originate from the Idol of the village, Reena was sent to calm it down, but did not return. Melfice is sent to investigate, with Ryudo unknowingly trailing behind. Melfice discovers her posessed by the Horns of Valmar and is forced to kill her, only to end up possessed himself.
Ryudo witnesses this event, not understanding why his brother would kill his own fiancee, and stays beside Reena's body, weeping.
Ryudo is greatly affected by Reena's fate. He loses trust in others, and becomes the cynical, pessimistic person first seen in the beginning of the game. He also comes to believe Melfice killed Reena just to obtain Valmar's power.
