Natts serves as a fairy companion to the Yes! Pretty Cure 5 GoGo! team. When Ego Ego assaults Tokyo and battles the Healin' Good Pretty Cure team, Natts arrives alongside Coco, Milky Rose, and the Yes! Pretty Cure 5 to aid against the swarming Ego Ego entities. During the conflict, Ego Ego captures both Natts and Coco, forcing the Yes! Pretty Cure 5 team to focus on their urgent rescue. Following their liberation, Natts persists in supporting both Pretty Cure teams during the final clash against Ego Ego after it absorbs Kaguya and undergoes a humanoid transformation.
