Aida Mana (相田 マナ Aida Mana?) (or Maya Aida in the English Dub Glitter Force Doki Doki) is one of the five main Cures in Doki Doki! Pretty Cure and she is also the leader of the group.
Her Cure alter ego is Cure Heart (キュアハート Kyua Hāto?), or Glitter Heart in the Glitter Force Doki Doki dub. Her catchphrase is "Kyunkyun!" (キュンキュン！ Kyun Kyun!?) which is the onomatopoeia that is used to express the tightening of one’s chest caused by the powerful warm feelings of love; the dub changes this to "Feel the Doki Doki!".
