Grace Synclavia is the current empress of Vatlantis as well as the younger sister of Aine.
Grace has pink-colored hair with patching pink eyes. While she greatly resembles her older sister Aine, Grace is slightly shorter than Aine and has a smaller bust and small but well-formed buttocks. Grace's usually "outfit" is a few white and gold accessories which barely hide her breast and crotch also her butt is exposed without any fabric to cover it. When she was a student on Ataraxia, she wore the school uniform.
Although she only appears for a few seconds in the final episode of the anime, her physical design may be more "mature" than the light novel.
Grace has a very short temper and is quick to anger. This is shown by the hatred she exhibits for Kizuna, seeing him as the 'Demon King of Lemuria' who took her sister away from her, and the one person Aine may care about more than her. This quickness to anger is seen as her largest flaw by enemies and allies alike, as it is very difficult to calm her (with the exception of Aine), and her magical power and prowess is reason enough to fear her.
While a student on Ataraxia, Grace was able to skip a grade and was in the same class as Kizuna. She also went by as Grace Synclavia Chidorigafuchi, the same surname her older sister had while on the Earth.
Although at the beginning Grace hated Kizuna, she later came to desire him to the point of masturbating while thinking about him in volume 11.
In volume 14 Grace thinks of Zelshione's son as her future partner, she believes that 15 years of difference isn't uncommon.
