Potpourri

Potpourri is Myoudouin Itsuki's mascot partner in Heartcatch Pretty Cure!. Potpourri is a baby fairy, unlike Chypre and Coffret. Being a baby fairy, Potpourri is childish and naive, but also protective of friends. Like the other fairies, Potpourri is never afraid to speak its mind.

Potpourri has the ability to generate powerful yellow shields, just like Cure Sunshine. Potpourri can also create a giant golden "capsule", capable of teleporting something as large as the Tree of Hearts, to another place. Although quite powerful, this requires help from Cure Sunshine and also takes a rather long time to completely finish.

Birth Chypre and Coffret, fairy mascots of Tsubomi Hanasaki And Kurumi Erika mention that the Heart Pot in the Tree of Hearts is glowing which would mean something special is about to come. Later on the Heart Pot gives birth to Potpourri. Dark Cure comes to destroy the Tree of Hearts but Potpourri tells her not to.

Meeting The Cures and Searching for the third Pretty Cure Candidate
When peace arrives once again, Potpourri reveals to the girls that it needs a Pretty Cure partner. The girls have not found a partner for it, and so an episode is dedicated to finding Cure Sunshine. The search, however, does not go well. Later on, Potpourri believes it found a candidate: the Gardening Club's president, Mizushima Aya. She, however, is disqualified after Potpourri found the true candidate, Myoudouin Itsuki.

Joining in the fight with Cure Sunshine
After finding Cure Sunshine, Potpurri joins the others at the Tree of Hearts. When Dark Cure arrives and attacks the group, Potpourri, upset that the tree is weakened again, is comforted by Cure Sunshine, and together they work to create a new barrier around the Tree of Hearts while Cure Blossom and Cure Marine distract Dark Cure. After succeeding, Pretty Cure and the fairies go back to the hospital, where Itsuki watches over her brother. Potpourri is happy that it has finally found it'd Pretty Cure partner.

When summer vacation ended and Itsuki had to return to school, Potpourri got angry and tried to get her attention. When this backfires and Itsuki scorns him, Potpourri runs away and meets another girl, Haruka, who has also run away. They meet up with Tsukikage Yuri, who tells them that they need to find their caretakers again. Just as a Desertrian arrives and Pretty Cure fights it off, Potpourri understands that Itsuki loves it, and is not mad at her anymore.

The Final Battle
Potpourri along with the other fairies journey to the Desert Planet to rescue Kaoruki. Kumojaki and Cobraja challenge the Cures to a final battle which Cure Marine and Cure Sunshine accept. Cobraja soon gets the upper hand in battle which causes Potpourri to jump infront of Cure Sunshine protecting her with it's shield. He tells Cobraja that Cure Sunshine is more beautiful than him due to how she wants to protect everyone's hearts and smiles. The two then join forces against Cobraja. They then use there shields together and use Sunshine Beam together. They then purify him with Gold Forte Burst and go to rejoin their fellow Cures and Fairies.

Relationships
Myoudouin Itsuki: During their first encounter, Potpourri already understood that Itsuki would be its Pretty Cure partner because of her strong warmth. It understands Itsuki's desire to protect people dear to her, which makes them more connected. Overall, Potpourri's immaturity makes it like Itsuki's little brother.

Tsukikage Yuri: When it first meets Yuri, it wants her to become its partner because it could sense her power. It is upset when she rejects it, but still loves her and tries to hug her on several occasions, feeling rejected whenever she pulls away.

Etymology
Potpourri: Potpourri's name comes from a mixture of dried plants used to provide fragrance.
