Nama is the female living armor who appears in the first episode of Slayers Evolution-R.

In Slayers EVOLUTION-R, a suit of Living Armor calling herself Nama appears, who bears many similarities to Naga. Although there is no explicit confirmation, it is strongly hinted in the series that Nama is in fact Naga's soul trapped in a suit of Living Armor. Both Nama and Naga are voiced by Maria Kawamura (although Nama's manner of speaking is noticeably different from Naga's, as Lina points out), have the same laugh, and have similar mannerisms. Furthermore, Nama states that she was a treasure hunter who got her soul trapped in the armor as the result of touching an enchanted pot. A flashback depicting this shows Nama as a silhouette, which strongly resembles Naga. Nama also told Amelia that her mother died when she was young and was lonely as a result. Finally, Nama can perform the Pacifist Crash attack, as she did in episode 3, a signature move of the Saillune royal family.
