Eustia Astraea

The title character, Eustia (everyone calls her Tia for short) was saved from having to work as a prostitute after Caim buys her. An orphan for as long as she could remember, Tia grew up under harsh conditions, having worked as a slave for a noble family before ending up in the “Prison”. She is cheerful and optimistic, and she believes that there is a greater purpose to her life from the periodic dreams she sees. She is driven by a huge desire to help and bring happiness to others, especially Caim, whom she looks up to as the one who changed her bitter life up to that point for the better.
