Dinah is Aera's Guardian Beast and a character in Summon Night Swordcraft Story 2. She also appeared in its anime version. Dinah is a devil who shares her body with an angel. The devil side prefers to be sarcastic and controlling, while the angel side abhors conflict. The devil controls the body most of the time, but in times of stress the angel is able to take over Dinah's body and speak out (usually to apologize for what the devil side was doing).
