Heart Crystal (FC☆PC)

Heart Crystals (ハートクリスタル Hātokurisutaru) are important items in FantasyClock☆Precure, which represent human hearts, much like Heartcatch Pretty Cure!'s Heart Flowers and ''Doki Doki! Pretty Cure's ''Psyches. When a person has feelings of grief, Disharmony's minions are able to turn their hearts into black Heart Crystals that create Disharmonizer’s. The person can only return to normal if the Heart Crystal is purified by a Pretty Cure.
