Potpourri is a fairy born from the Heart Tree in *Heartcatch Precure!*, characterized by yellow and white coloring distinct from other fairies like Chypre and Coffret. Emerging as the third fairy after the collection of Heart Seeds, Potpourri's core purpose is protecting the Heart Tree using potent sunflower-shaped barrier spells. This drive to protect extends universally, motivating action even when aware of personal limits. The character displays a dual nature: possessing unusual wisdom and calmness for infancy, yet also exhibiting strong childlike impulsiveness. This impulsiveness often surfaces during the search for the destined partner for the PreCure Seed, leading to independent actions that clash with fellow fairies Chypre and Coffret. Potpourri identifies Itsuki Myoudouin as Cure Sunshine's candidate, bonding over their shared dedication to protection. Despite this responsibility, Potpourri retains playful, baby-like tendencies, prioritizing playtime with Itsuki and requiring reminders about duties from the other fairies. Within *Precure All Stars New Stage: Mirai no Tomodachi*, Potpourri appears among assembled mascots including Chypre, Coffret, Hummy, and Candy, initially celebrating Fusion's defeat. During the climactic battle against Fusion's spawn in Yokohama, Potpourri intervenes to shield the human protagonist Ayumi Sakagami from an attack. This coincides with the arrival of the *Heartcatch* and *Fresh* Pretty Cure teams, reinforcing the fairy's protective role.
