Happy Go Lucky! Doki Doki! Pretty Cure

Happy Go Lucky! Dokidoki! Pretty Cure (ハッピーゴーラッキー！ドキドキ！プリキュア)is the Opening song of Doki Doki! Pretty Cure. It started airing from Episode 1 on 3 February 2013.

The song later appears in, Doki Doki! Pretty Cure Original Soundtrack 1: Pretty Cure Sound Link Love! and it is remixed into Heroic Instrumental.

The opening is later changed as in, Episode 27, because of Cure Ace's, and Regina's appearance.

Trivia

 * Part of this song was first shown after Smile Pretty Cure!'s Episode 45, following a trailer for Doki Doki! Pretty Cure. 
 * The first shot of the opening is a Psyche floating in space, similar to the heart at the beginning of Alright! Heartcatch Pretty Cure!.
 * The ending of the opening changes in Episode 7 from the girls looking at the purified Psyches in their Cure forms to the girls looking at the purified hearts in their Cure AND Civilian forms.
 * Regina appeared also in the other openings before her official appearance. However, Regina did not fully appear, as only her silhouette was shown.
