Saria and Elva are twin operatives from Dayereh, characterized by light grey hair, red eyes, and darkened skin. They present themselves as quiet, innocent, and vulnerable children to manipulate others, such as endearing themselves to Alfred Albert after his rescue near a massacre site. This facade conceals their true deceitful, cruel, and manipulative nature as agents of Rugis F. Camellia's rebellion against Hortensia. Their mission involves infiltrating Hortensia to retrieve a relic for Rugis, employing tactics like orchestrating merchant slaughters to summon demons and wielding dark magic to conjure creatures including zombies and a dragon. Their powers can be nullified by figures such as Pope Alexis. Though they display a twisted fondness for Alfred—warning him against interference to spare his life—they prioritize objectives above all, eliminating allies or obstacles indiscriminately. Their loyalty is exclusively to Rugis, prompting retreats when confronting formidable foes like Didier Vialdo. No significant evolution or redemption occurs in their documented actions or motivations.
