Kayla, daughter of Chef Jack and younger sister of Chase, works as a kitchen assistant alongside her brother. Her duties focus on dishwashing and guarding the Mobile Attack Cuisine Cart. Though only eight years old, she shows resilience and strong-heartedness, tempered by a tendency towards easily provoked anger. Her constant companion is her Foodon, Omelet, who typically stays by her side while she guards the cart. Kayla shares her family's commitment to battling the Gluttons. Her signature culinary creation is the extremely spicy "Five Star Chili Breakfast," known to trigger intense reactions like fire-breathing; she also prepares a less potent "Three Star Chili Breakfast." Her relationship with Chase involves both loyalty and typical sibling dynamics, including competition for his attention against Coco.

A significant event sees Kayla and her Foodon Pie Tin fall under Rose Marinade's trickery, temporarily switching allegiance to the Gluttons. During this brainwashing, her personality shifts dramatically to sadistic, taking pleasure in cruelty towards workers. Her appearance also changes: she adopts a midriff-baring top with a faux fur shoulder pad on one side, a miniskirt, and high boots – a stark contrast to her usual lavender dress, pink vest, white socks, and red Mary Janes. This condition is reversed by the conclusion of events, restoring her original personality and attire.

Kayla possesses long green hair styled in odango buns, light skin, and brown eyes. In combat, she utilizes her Foodon in battles characterized by normal-type attacks.
