The Embryo (エンブリーオ Enburīo) is a special egg that has the power to make anyone's wish come true. Unlike other eggs, it flies around in the sky instead of living inside the heart of a person and can only be lured out if there are Heart's Eggs gathered.
HistoryEdit
The Embryo is the item that motivates the first part of the story, as the Guardians and theEaster Company are out to find the Embryo in order to fulfill their own wishes. In chapter 41and episode 102, the Embryo is revealed to beHikaru's Heart's Egg. The reason it was never in his heart was because it was driven out by Hikaru, who wanted to stop feeling loneliness. After it was driven out, it began to look for its owner. Thanks to Amu and her Guardian Characters, the egg is able to return to Hikaru. In chapter 45, Amu's Guardian Characters, Ran, Miki, and Suu, disappear from existence. To find them again, Amu goes on a journey with her last Guardian Character, Dia, andTadase and Kiseki to find the four sparkling shards that will lead her to the Embryo and help her make a wish come true. It is revealed in the last page of chapter 48 (the final chapter) that the embryo is every single Heart's Egg, meaning the Easter's attempts to capture the Embryo were all in vain.
