Hiya

Hiya is the demon who rules over light and darkness. After she was freed, she granted the blond Hero 3 wishes, one of which was to kill Furio. When she attacked him, she was utterly defeated by Furio who has furious at her as she had injured Fenris. Fenris recovered fast and calmed Furio, proposing to have Hiya become their servant, to what she obviously didn't and couldn't oppose.
