Minto was initially depicted as spoiled, snobbish, and self-centered because of her wealth (like most rich girls), but is later shown to really be an empathetic, kind, and loving person who cares deeply about her friends.
Mint is a talented dancer and is very flexible and gracious. Despite her fragile appearance, she is very enduring. She demonstrates a certain skill in hand-to-hand combat, even if she doesn't show it all the time. She knows how to swim. She seems to have archery skills, as demonstrated by her use of the MinTone Arrow.
