Gracia Ul Naga Saillune
白蛇のナーガ
Naga’s real full name is Gracia Ul Naga Saillune, making her the first daughter of Crown Prince Philionel El Di Saillune and the older sister of Amelia Wil Tesla Saillune.
Although, Naga is the older sister of Amelia Wil Tesla Saillune, the pair have never met in the series when both were aware of the other’s identity.
Naga’s mother was murdered before her own eyes several years before the start of the series by the famous assassin Booley. As a result, Naga slayed her mother’s killer with the crown princess’ original spell, Chaos String. After the funeral, Naga found the outrageous outfit she currently wears inside her mother’s closet. Shortly afterward, she left home in order to learn the ways of the world.
