Coupe

Coupe (known also as the mysterious guy) is another fairy from the Tree of Hearts, and the source of the botanical garden's protection field. He is of higher rank then Chypre, Coffret, and later Potpourri, causing the smaller fairies to look up to him. Although he never talks, he observes Tsubomi Hanasaki and Erika Kurumi whenever they visit the garden. Just as Chypre, Coffret, Potpourri, and Cologne are to Tsubomi, Erika, Itsuki, and Yuri, Coupe is the fairy companion of Kaoruko Hanasaki, who in the past was Cure Flower. He is capable of transforming into a human, having chosen to take the appearance of Kaoruko's late husband, Sora Hanasaki, out of love for his partner. Using this form, he saves Pretty Cure whenever they cannot get away from a deadly situation. However, as he does not talk when human, the girls just refer to him as the hot guy. Tsubomi Hanasaki seems to have had a small crush on him, though this changes when she finds out his secret.

Trivia

 * Coupe's human transformation abilities are a nod to the mascots of Yes! Pretty Cure 5/Yes! Pretty Cure 5 GoGo! and Suite Pretty Cure♪, in which the main mascots of the series have the ability to become humans to roam freely in town. Unlike them, however, Coupe only uses it to be capable of fighting and only when needed, while in Yes! Pretty Cure 5 and Yes! Pretty Cure 5 GoGo! only Milk earns the ability to fight in battle. Siren also has the ability to turn into a human being in Suite Pretty Cure♪, but somehow lost it after Episode 21.
 * Though he is an upperclassmen to the other fairies, Coupe is very different from the others. He has the signature tail of the fairies, but is also very big and doesn't have the "cute" look to him, though it is possible that he was once smaller. His appearance could be to show how the fairies mature but this has not been stated in the series.
 * Coupe rarely ever speaks and the only time he does was in Sora's form testing Cure Blossom, Cure Marine and Cure Sunshine to see if they were worthy of the HeartCatch Mirage. After they defeated him he smiled and said "You've grown" before changing back to his normal fom. He usually communicates to the others through simple eye movements and pointing. Regardless of his near silence, he is also an extremely loyal partner to Kaoruko.
