Seira Vix

Seira Vix (セイラ・ヴィクス) is the princess of the Imperial District of Vixia. She is the original of Aries.

Appearance
She looks like an older version of Aries, with longer hair. Like Aries, she has heterochromia. She wears dresses in the Vixian style, which resemble those of old Europe.

Personality
Seira is shown to be a very kind and moralistic person, and Charce describes her as being strong, but also noble and gentle. She stands up for her beliefs, and even goes behind her father's back to keep her clone safe from him. She acts as an older sister to Charce, and tries to encourage him to have a life outside of being a replacement body for her father.

Background
Before the start of the series, her father genetically engineered a clone for her without her knowledge, in order to be used for spare body parts. Seira, aghast at this, fakes the death of her clone and forbids her father from ever cloning her again. She then acts as an older sister to Charce, who she regrets being unable to save from her father's ambitions. Later on, she is pushed from a cliff by an assassin while out on a walk with Charce, and dies.

Charce Lacroix
She acted as an older sister figure for him, and cared for him a great deal. She often took him outside to observe various plants and insects. Charce said that the time he spent with Seira was the most fun he ever had.

Noah Vix
Noah wants nothing more than his and his daughter's safety, but he goes to extremes to try to ensure this and Seira doesn't approve of his actions. She acts defiantly towards him and is greatly disturbed by the person he's become.

Emma Spring
Emma was one of Seira's maids, and Seira trusted her a great deal.
