The mayor of Terra, which she received from her own abilities. Later, she tried to find a mate, but after being heartbroken by many men, she gave up and asked the church to cast a spell that would allow her to become pregnant on her own. Later, she became pregnant on her own with the blessing of the gods. Later, she adopted an abandoned elf girl and named her Alona, ​​and she loved this child like her own daughter. At that time, she was 8 months pregnant, and 2 months later, she gave birth to a daughter and named her Mewfi. She was a very strong child. And with Rosia's own abilities, she is considered a very good mayor without having a mate. And she is also closer friends with the Duke of Bellefort than usual. But the two do not bring their daughters to meet often. Mostly, the Female duke will meet Mewfi. As for Rosia, she often meets the eldest son of the Female duke. Because Alona likes to go to the city to help the villagers, so the Female duke does not often meet. As for the duke's daughter, she likes to train for fighting regularly.
