Psyches

Psyches (プシュケ Pushuke) are important items in Doki Doki! Pretty Cure, which represent human hearts, much like Heartcatch Pretty Cure!'s Heart Flowers. When a person harbors selfish feelings, they usually try not to give in to them, but if one of Selfish King's minions is around, the Psyche is forcibly turned black, extracted from its owner and used to create a Jikochū. Psyches usually look like pink heart-shaped brooches with white angel wings; when turned black, they grow bat wings instead.
