Personality
Heine appears to be a more serious nature then her partner Juliet, chastising her when she speaks too freely of their leader's homeland folktales, while calling her out of her name when she referred to herself as the "black angel", giving her a sense of witty retort to the obvious.

Alvarez Empire arc
Heine, along with Juliet and the rest of her squad, are sent to eliminate the Ishgar resistance that is located in the northern boarder, successfully defeating the first wave. While Irene talks the of an old folktale of Mt. Zonia, she chastises her partner for whimsically talking about their leader's homeland, while retreating back when Juliet returns the favor, questioning her own words.Irene likens the comparison of the black and white angel she spoke of to the duo; Heine dismissing the idiocy of her partner's comments. Irene then wonders who would come out victorious between the two girls, only to mention it was only a joke, calming their nerves. Heine then watches Irene completely alter the snowy mountain's climate, standing in awe of her power.
