Eria Sein is a half-blood human of Yaksha clan heritage, and one of the thieves who stole the item box that contained the Golden Knight in Atera.


When Ari tells Airi to watch Lorraine's box because it contains a god-level item, she abandons it instead.[1] The thieves overhear the conversation and decide to steal the goods.[2]

Despite being thieves, neither of them seem to be particularly violent, as they plan on using evasive measures in the theft, wait for God Kubera disguised as a kid to leave the scene, and are even concerned about their pursuer's well-being. They escape on the rooftops, jump down from Atera's high wall, and run into the nearby forest, where their movement is stopped by God Kubera's Binding of God, which makes the stolen box too heavy for them to carry. They drop the box and decide to grab the most valuable items from it and leave the rest. The half-blood thief quickly realizes that the silver bracelet is the god-level item, and enlightens her partner about it. Since they deem the bracelet to be useless directly, they decide to sell it for a high price instead, and are finally stopped by the appearance of adult God Kubera. They instantly flee the scene while begging for forgiveness and promising to live good lives henceforth.[3]
