Greta is a character from the OVA A Little Snow Fairy Sugar Summer Special, which is set several years after the main television series. In this special, she and the other children from the fictional German town of Muhlenburg are approximately fifteen years old, having grown up together since the events of the original story. She comes from a wealthy family, a background that has significantly shaped her outward demeanor and initial interactions with her peers.

Throughout the main series, Greta positions herself as a self-proclaimed rival to the protagonist, Saga Bergman. Her personality is characterized by a strong sense of pride, arrogance, and boastfulness, often leading her to challenge Saga to various contests and competitions. However, these challenges are not born out of malice but rather from a deep-seated admiration for Saga. Greta craves recognition and attention, and her competitive actions are primarily a flawed but earnest attempt to connect with Saga and secure her friendship, as she envies Saga’s popularity and wishes to be included in her circle of friends. She has poor social skills and does not know how to express her desire for a peer, which leads her to act out in a confrontational manner. Beneath her condescending facade, she shows moments of unexpected kindness and is not genuinely selfish, but rather a lonely girl seeking a worthy companion.

In the Summer Special, Greta’s role is directly tied to a school play written by their classmate, Anne. The play is titled The Princess and the Fairy, and in this production, Saga volunteers for and portrays the Princess while Greta takes on the role of the antagonistic Evil Witch. This casting choice serves as a deliberate narrative echo of the dynamic the two girls have shared throughout their childhood, with Greta embodying the antagonist role that mirrors her history as Saga’s rival. Her involvement in the play underscores her continued presence in Saga’s life as they have grown older, and the special ultimately shows that their bond has matured past simple rivalry into a form of mutual respect and enduring friendship. The story confirms that Greta and Saga remain friends in their teenage years, with Greta still being somewhat socially awkward but accepted by Saga for who she is. One of her most defining traits is her genuine loyalty as a friend, demonstrated in the past by a significant gesture of giving up something important to her for Saga’s sake.

No specific information regarding any unusual or magical abilities belonging to Greta is available. Her character is defined not by supernatural traits but by her realistic and relatable human emotions of loneliness, pride, and the desire for friendship and approval.
