Spirit Guardian

The Spirit Guardians (精霊守) are a group of very powerful mages from the Heart Kingdom.

Overview
Spirit Guardians are powerful Stage Zero-ranked mages who can borrow the power of natural mana. They serve as protectors of the Heart Kingdom and Princess.

In exchange for the Clover Kingdom's aid in fighting Megicula and the Spade Kingdom, five Spirit Guardians train several Magic Knights for six months.

When Vanica invades the Heart Kingdom, four of her Dark Disciples easily defeat four Spirit Guardians.
