In the context of the English-language adaptation of the anime, Corinna is known as Corina Bucksworth, the counterpart to the original Japanese character Minto Aizawa. She is among the main heroines and the second member to be discovered and recruited into the team of heroines. Corinna comes from an exceptionally wealthy family and is the heiress to a considerable fortune, living in a large mansion. Her family life is marked by the notable absence of her parents, who are frequently away from home and do not attend her important events, leading her to spend more time with her grandmother or a nanny. This sense of isolation extends to her relationship with her older brother, Seiji or Sergio in the adaptation, from whom she grew distant as he became consumed with his own studies and responsibilities. She owns a small pet dog named Miki or Brutus, for whom she cares deeply.

Corinna’s personality is initially defined by a snobbish, spoiled, and self-centered demeanor, a trait she often demonstrates by shirking her duties at the Café and insisting on precise tea times. However, this behavior is a facade that conceals a deep-seated fear of being hurt emotionally, as well as profound loneliness stemming from her isolated upbringing. As the series progresses, she reveals herself to be an empathetic and caring individual who comes to value her friendships immensely. A defining aspect of her character is her intense admiration for another team member, Zakuro Fujiwara, known as Renee in the adaptation. She idolizes Zakuro as a sophisticated and strong role model, and is deeply affected when Zakuro initially refuses to join the team, to the point of despair. Her motivations are largely driven by a desire for genuine connection and to protect those she cares about, overcoming her own fears to stand with her teammates.

Within the story, Corinna serves as a core member of the team, often acting as a foil to the protagonist with her refined, ballet-inspired fighting style contrasting with more brawling approaches. Her role is cemented when her pet dog is transformed into a monster, an event that forces her initial transformation and reveals her powers. Her relationship with Ichigo Momomiya, known as Zoey in the adaptation, starts with mutual friction due to Corinna’s haughty attitude but develops into a deep, reliable friendship. The relationship with Zakuro is pivotal; Zakuro’s tough love ultimately helps Corinna confront her own insecurities when she tries to quit the team. Her relationship with her brother is also a key source of development, as a significant episode revolves around her desire for his recognition and her anger when he is hurt by a monster, showcasing her fierce protective side.

Corinna undergoes notable development throughout the narrative, transforming from a lonely, privileged girl who rejects friendship to a loyal and supportive friend who actively fights for her team. A turning point occurs when she confesses her fear of being hurt as the reason for wanting to leave the group, only to realize, with Zakuro’s help, that having something to protect is worth the risk. By the end of the series, she has matured significantly, having grown past her selfishness and used her own experiences to empathize with and help others who are similarly lonely.

Corinna’s notable abilities are derived from her DNA infusion with the Ultramarine Lorikeet, which grants her avian characteristics. Upon transforming into Mew Mint or Mew Corina, she sprouts blue bird wings and a tail, which allow her to fly. In the anime, she can also communicate with birds. Her fighting style is heavily integrated with her training as a prima ballerina, as she incorporates elegant ballet moves like arabesques and pirouettes into her combat. Her primary weapon is the Mint Arrow or Heart Arrow, and her signature attack is called Ribbon Mint Echo, which she uses to purify monsters.
