Smyrna is Serena's older sister and the past life of Kagami Shinogu. While her looks attracted many men, she harbored a strong hatred for them. She is very kind to women, considering she is attracted to them. She has a sister complex and dotes on Serena. As such, she is extremely hostile towards Sirix, going so far as to beat him with a whip or send assassins after him. Despite her tremendous strength, Smyrna is quite frail and tires easily, something which she passed down to Shinogu.
