Heart Kingdom

The Heart Kingdom (ハート王国) is a country bordering the Clover Kingdom. It is the home of Undine, the spirit of water, who formed a covenant with the country's rulers. The current ruler is Princess Lolopechka, and she has entered into an alliance with the Clover Kingdom to invade the Spade Kingdom.

Description
The Heart Kingdom lies to the south of the Clover Kingdom. This country of green and water is rich with resources. Generations of princesses have used the power of Undine to protect the country. With a Mana Zone that extends over the entire country, the Princess herself can monitor everything going on in the country and even assist in sustaining its forests and crops by using her Water Magic and guards the kingdoms borders with powerful Trap Magic. Nobles of the Clover Kingdom are allowed to submit requests for entry and studying the country's magic.

The kingdom has its own system for rating a mage's skill and talent. It is divided into ten Magic Stages, with Stage Zero at the top and Ninth Stage at the bottom. The Kingdom itself possesses five Spirit Guardians who are ranked as Stage Zero.

Magic Technique
Over the centuries, the citizens have adapted to the country's strong natural mana and developed a unique magic technique to channel that mana into spells, increasing their strength and abilities. The user instructs the mana to perform various actions through arrangements of runes. This can be applied directly to a spell or be formed into a larger magic circle. Since it uses natural mana, it is limited to magic attributes that can be found in nature, such as the four major elements and plant-based attributes.

Mages of the Fifth Stage and below are too weak to form the runes properly, and only mages of the Third Stage or higher are skilled enough to use the technique in combat scenarios.
