Coco, a fairy co-managing Fairy Park alongside Natts, serves as a primary organizer and presenter. To host park events and showcase its central attraction—the Rainbow Jewel embodying the world's collective hopes and dreams—he temporarily assumes human form. His merchant background and royal status consistently inform his activities within the park.

Integral to park operations, Coco participates in distributing Miracle Lights to visitors. These objects harness positive emotions and play a crucial role in empowering Pretty Cure teams during confrontations. When the entity Bottom revives villains from different eras to steal the Rainbow Jewel, Fairy Park becomes the central battleground. Coco indirectly supports the Pretty Cure teams by maintaining the park's infrastructure and facilitating the distribution of Miracle Lights, which contribute to the heroes' collective strength.

His essential partnership with Natts underpins the park's functioning. Their collaborative efforts establish the venue as a convergence point for multiple Pretty Cure teams, enabling a coordinated defense against Bottom's forces during the crisis.
