Carolina teaches at Mardaquelle Yovaca Kindergarten in Mexico, where Shinnosuke Nohara joins following his family's move. She has light tan skin, green eyes, and brown hair featuring a prominent right-side curl with a smaller left section. Her standard outfit includes a light cyan short-sleeved dress with pale blue waist frills, blue tight pants, strapless red dress shoes, and a black sport tank top beneath the dress. Her voluptuous figure, with ample breasts and a large, curvaceous rear, frequently draws Shinnosuke's notice during her dance movements.

Cheerful and bright-natured, Carolina displays caring, kind, and compassionate traits toward students like Shinnosuke. She exhibits courage and resourcefulness against hostile Killer Cacti, participating in efforts to defeat their queen and protect the town. Her combat improvisations include wrapping stones in clothing to break locks or wield as whips. Dedicated to her pupils, she aids the Nohara family in searching for a missing Shinnosuke. During the final cacti battle, Misae Nohara entrusts Shinnosuke's safety to Carolina, indicating mutual trust.

Her dancing impresses Shinnosuke, especially sharp rear movements, and she fulfills a post-conflict promise to dance with him. In an affectionate gesture, she playfully kisses Shinnosuke in appreciation for his role in saving the town.

Her narrative role centers on supporting protagonists during the cactus threat, leveraging physical abilities, courage, and emotional ties to Shinnosuke and his family throughout the Mexico events.
