The Guardians are the student council of Seimine Academy designed to protect the students and the school, and secretly keep children's heart's eggs safe and preserve them while looking for the Embryo - the legendary heart's egg that has the power to grant wishes, as well as fighting against the Easter Company, a powerful corporation also aimed at obtaining the egg.

Each of the members has at least one Guardian Character to grant them special powers in tight situations. The Guardians usually have special or secret meetings in the Royal Garden of Seimine Academy.

This organization was founded by Seimine Academy's principal, who is named Tsukasa Amakawa - the first King's Chair, also known as the Founding King.


The Guardians are traditionally recruited with limited to 10 kids with Guardian Characters in four positions known as the King's Chair, Queen's Chair, Jack's Chair, Ace's Chair.

Following the Founding King's instructions, when a person with three Guardian Characters appeared, a special position was granted to that person - Joker. Such person will be given the power to wield the Humpty Lock, which allowed them to purify those heart's eggs whose owners have tainted it with an X, something most Guardian Bearers cannot accomplish.

Royal Capes

Royal Cape
The Royal Capes are worn by the Guardians only during meetings or special events. The capes have a plaid pattern, however the male Guardians wear a blue cape, where as the female Guardians wear red capes.


  • The positions of the Guardian are based on Cards. K, Q, J, A and Joker.
  • Lynné, Millay, Clyna and Syrine's Guardian Characters are based on Cards too.
  • Lynné didn't wear a cape usually, because the image didn't fit her cool and spicy character in school, and this fact is also the reason why she didn't want to join The Guardians even though she had her Guardian Characters. The cape is also shown to clash with her uniform, as Lynné also wears a red band on her arm and black boots. She began to wear it a lot but still not usually. She wears her cap with a buckle belt instead of button.
  • Syrine wears her cape with a Dark Red Ribbon with a red jewelry on it.
