Each kingdom receives its own arc, strategically placed to elevate Asta and the other Clover Kingdom characters as they overcome hurdles and grow stronger. While every kingdom is unique and has contributed something distinctive to the story, the power structure remains clear. Here is how each kingdom is ranked by power.
4) Diamond Kingdom

The Diamond Kingdom in Black Clover, located north of the Clover Kingdom, is the first to be revealed to fans through its attempts to invade the Clover Kingdom. At the time of its introduction, the kingdom’s main power stemmed from the Magic Scholar Moris Libardirt, who engineered Magic Knights using magic stones to create his secret puppet and take control of the kingdom. It was also revealed that the Diamond Kingdom suffered from a lack of resources, which led its Magic Knights to frequently invade other nations in search of supplies.
The strongest warrior introduced was Mars, who led the Eight Shining Generals, the most powerful warriors of the Diamond Kingdom, though they were eventually defeated by the Black Bulls and the witches of the Witches’ Forest. The Diamond Kingdom has consistently been depicted as the weakest of the four powers as time passed for Black Clover, with the Spade Kingdom’s Zenon Zogratis single-handedly defeating its military, a testament to its low standing. However, with the Diamond Kingdom rising once again, it seems they may be stronger than before.
3) Heart Kingdom

Following the introduction of the Diamond Kingdom, the Heart Kingdom is the next to be revealed. Among the four kingdoms, the Heart Kingdom is shown to be the most resourceful, especially in terms of mana. Its abundance of mana is its greatest strength, which also aided the Magic Knights of the Clover Kingdom in becoming stronger. Additionally, the kingdom is home to Undine, the Water Spirit, one of the elemental spirits in Black Clover, who is directly connected to the kingdom’s queen.
The Heart Kingdom’s primary role was to train the main characters, leading to a confrontation against Vanica Zogratis of the Spade Kingdom, where the other three kingdoms united to stop the invasion. With its vast resources and abundance of mana, the Heart Kingdom stands as one of the most powerful realms with deep potential. In theory, it could even surpass the Clover Kingdom, though the Clover Kingdom’s newest generation has been able to grow and consolidate its power the most.
