A happy-go-lucky, bubbly and playful young girl, Nora is mainly characterized by her boundless enthusiasm. When Nora talks, many of her words may sometimes come out randomly without her actually giving much thought to anything she comes up with. This is caused by her tendency to jump into a different topic most of the time and her rather peculiar imagination. Because of this and her free-spirited attitude, Nora's personality changes according to her mood and she is prone to becoming a nuisance to the people around her, losing the point of a conversation, or even experiencing anxiety attacks. However, Nora is more insightful than one would think and is capable of being serious when mostly necessary. This rare sense of seriousness of hers is most prominently displayed during the battle against the Nuckelavee, where she literally slaps sense into Ren who was consumed in his need for revenge against the Grimm who wiped out his village and family.
