Naga the Serpent, also known as Gracia Ul Naga Saillune, would describe herself as a flamboyant, eccentric, and powerful sorceress with a noble lineage. She is the eldest daughter of the Holy Kingdom of Saillune's crown prince and the older sister of Amelia Wil Tesla Saillune. Naga possesses a annoying distinct laugh (OHOHO!) and an absurdly large chest. Despite her rivalry with Lina Inverse, a renowned teenage sorceress, Naga often acts as Lina's sidekick in their adventurous exploits.
