Crystal Hearts

Where They Come From

In both worlds (Magical and Human), Crystal Hearts come from both humans and witches and can be released with a witch's powers. Their color depends on which mood the human/witch is in.

Usages

Ecure

Crystal hearts can be used for currency called "Ecure" in order to purchase anything from the magical world. They can also be used as an power source as mentioned by Queen Candy in a volume of the Sugar Sugar Rune manga.

Marriages

In the Magical World, a couple can be officially married by swapping each other's crystal hearts. However, this cannot be reversed, and in attempted, it could end up killing them.

Special Hearts

Three types of special hearts also exist in both the SSR franchise. Noir (Black) Hearts, Rainbow Hearts, and Blanc (White) Hearts. Noir hearts exist when a human/witch is jealous or has a hatred for someone. They cannot be collected as Ecure and can also hurt witches much more than ogres, whom are the rouge witches of the magical world. They can be turned into white hearts by a "Filter", which a rare amount of witches are. When a white heart is given to a familiar, the familiar can change back to their human form. For example, in the conclusion of volume 6 of the SSR manga, when Chocolat gave Duke a white heart, Duke changed to his human form and from then on goes by the name of Poivre. Rainbow Hearts exist when someone is highly amused or when they're having fun. They are worth 500 ecure. (This only happens in the SSR anime.)

When One Loses/Swaps a Crystal Heart

Humans can reproduce crystal hearts in a snap after they are taken by a witch. They can also swap hearts when their love is true. If a witch's heart gets taken they can be killed by this because they can only contain one crystal heart. Witches can swap hearts, but only when they confirm their marriages in the magical world. This cannot be undone and the witch has to be with his/her spouse for the rest of his/her life (it's also a reason why most witches in the magical world don't get married).
