In *Gude Crest - The Emblem of Gude*, no concrete details exist for a character named Rubilia. The narrative follows Efera (Efe) and Jiliora (Jira) as they flee slavery to deliver Kilian’s pendant to his siblings Yurion and Rubiera. Kilian’s sister is identified as Rubiera in the Japanese version and Rubiera in the Enoki Films adaptation. Sources specify nothing about Rubiera’s background, appearance, personality, or role beyond her familial connection. The name Rubilia occurs in unrelated contexts—such as *Tower of Fantasy*, *Re:Monster*, and an unspecified anime—referring to distinct characters unconnected to *Gude Crest*.
