Esty Erhard

Esty is first introduced in Atelier Rorona as the hard working Adventurer's Guild receptionist. She is a very kind and helpful person who aids Rorona in her journey by giving her requests which will boost her reputation with the city. She is friends with Sterk and seems to be quite loyal to the king. As the series progresses, Esty becomes increasingly unhappy about her loss of youth and lack of a husband. During the events of Atelier Totori, Filly has taken over Esty's job and now works as the receptionist. Filly explains that her older sister was concerned about getting too old to find a husband, and so she is supposedly out in search of a man and is not seen in the game. In Atelier Meruru, she has seemingly given up her search for a husband, and is focusing on her career. She seems somewhat resigned to having chosen a career over marriage, but is clearly unhappy about it. When she drinks, Esty often reminices about her age. She watches closely over her sister Filly and worries about her sister's lack of skill with people. When she learns about the Potion of Youth, she is very determined to have some.
