Vanessa is a sincere, honest and honorable knight of Frelia. She takes her work very seriously and as Forde says, "needs to loosen up." She is calm even in the craziest situations, and is slightly envious of her sister's relaxed personality. She tends to take things seriously, and can never tell when the people are joking or being truthful. She has a dry sense of humor, and often scolds Forde for falling asleep in battle. However, she can be slightly mischievous at times, as seen in her A support with Lute, where she convinces her that the wings of a thousand pegasi act as an extremely potent aphrodisiac. She is good friends with Lute and Moulder, who acts as a father figure to her.

Vanessa is level-headed and always does the right thing. In a support with Syrene it is revealed that when their father suddenly got sick, Syrene and their mother panicked and did not know what to do, but Vanessa just knelt down and started to gather nuts in her hands, went off and sold them, and came back with medicine for her father. It is also revealed that she is always trying to be like her sister but can never seem to catch up with her, to which her sister replies she has always wished she could be more like Vanessa with her calmness even in the middle of crisis and battle.
