Ryo Asuka's mother was a minor character from the original Devilman. She was only seen in an old photo with her husband Professor Asuka.


She was a young woman of Caucasian descent. Like her son Ryo, she had blonde hair and blue eyes.


She assisted Professor Asuka on several expeditions as an assitant, eventually marrying him and giving birth to their son Ryo Asuka. She presumably had died several years before the events of Devilman take place as she was nowhere else to be seen even after Satan took Ryo's identity.
