Eluterina Rondorbell

Background
The manager of Echigoya main branch.

"She's one of the female explorers who were left in the Ivy Mansion. They were people without aim, but since they were formerly nobles, they could read and write of course. I've employed them in Echigoya Firm, since there were educated people available. Among them, this newly appointed manager girl was from lineage that extended to some Royal Capital's noble and unexpectedly well-known, so it was convenient."
