Ayumi Momozono is mother to Love Momozono, wife to Keitarou Momozono, and eventually foster mother to Setsuna Higashi. She possesses fair skin, large partially curved brown eyes, and short chin-length dirty blonde hair. Her hair appears partially fluffed and sticks out on the sides, featuring short pointed bangs typically brushed to the side. She commonly wears a work sweater, an apron-like dress, and simple heels. Employed as a local supermarket clerk, she frequently performs household chores like cleaning and cooking, often working overtime.
Ayumi exhibits deep kindness and care for her family, especially Love, though she occasionally adopts a stern approach when disciplining her over dietary habits. She fundamentally supports and trusts Love's abilities. Sharing traits with her daughter, Ayumi is selective about food and displays pouting expressions when displeased; she actively encourages Love to eat vegetables, particularly carrots, using gentle persuasion or minor incentives. Her insistence intensifies when Love avoids vegetables entirely, and she notably dislikes spinach. Ayumi maintains an exceptionally close bond with Love, viewing her as a "heart and soul" companion and serving as a role model whom Love assists with chores out of admiration.
In a key early interaction, Ayumi surprises Love with a ticket to the Trinity dance concert, sparking Love’s initial motivation. Later, when Love prepares hamburgers, Ayumi suggests adding carrots, causing Love’s displeasure. After a supernatural incident makes the hamburgers vanish, Ayumi mistakenly blames Love for eating them. This misunderstanding erupts into an argument where Love shouts that she hates her mother, deeply upsetting Ayumi. The conflict resolves when Love apologizes after the supernatural interference is addressed.
Upon learning of Setsuna’s circumstances, Ayumi agrees to take her in, formally welcoming her into the family. She values Setsuna’s household assistance and treats her with equal maternal care. Discovering Love and Setsuna are Pretty Cure warriors, Ayumi expresses distress and reluctance due to safety concerns. Though initially resistant to their mission to Labyrinth, she ultimately accepts their roles, offering Love a hug before their departure.
