While normally seeming shy and timid, Noire seems to have a serious bipolar issue, with her entire personality changing at random points mid-conversation. When her personality changes, she acts more like her mother, seeming to be crazy and psychotic. Noire is aware of her split personality and admits to a female Morgan that she slips into her psychotic persona in order to get rid of stress. When she isn't in the throes of raving madness, she is shy and relies for others to help her. She is even still uncomfortable with using the bathroom at night, and often asks Severa to go with her. Noire's shyness stemmed from Tharja using her as a guinea pig for her hexes. Despite this, Noire looks up to Tharja and wants to learn hexes from her to gain her approval. Noire's split personality can be attributed to the talisman, a gift from Tharja, that she wears to help cope with her shy nature.
