After travelling to Vile Root, Momo gained the courage to do things by herself, even deciding to cut a long length of her hair.
Her way of talking has also changed greatly. Momo has started speaking in a more eloquent and formal manner unlike how she used to when she first appeared (which was casual and informal before), thus maturing. She is also very soft-spoken.
She has also started to take notice of manners and values, and she earns a more silent and calm demeanor. Despite that, she remains optimistic and cheerful, and her level of amazement to new things has also increased. She also isn't afraid to stop and make a joke or two.

In her childhood, she wasn't allowed to go outside of the mansion, nor explore Macaria freely like a child would, Instead, she is forced to stay home to study economics, language, music, art, swordplay, and other activities that her father and mother would require her to learn. She only manages to walk around the town when her parents decided to send her and her brother to a nearby school, where they met Red and Adré.
