This world is an isekai fantasy where magic exists. The setting is the Kingdom of Melt. Everyone here uses magic. There are five elemental attributes: ・Fire: High power but relatively difficult to handle. ・Water: Easy to use and versatile, but easily countered. ・Wood: Specializes in durability through healing and support, but lacks solo offensive power. ・Earth: Excels at brute force through mass and terrain manipulation; however, its heavy strikes leave large openings, making it disadvantaged against agile opponents. ・Thunder: Possesses overwhelming speed and power but lacks durability.

There are five ranks among magic users: Apprentice, Mage, Sorcerer, Wizard, and Sage. Apprentice is the rank given to children. Mage is the level of an average person capable of basic magic. Sorcerer is the rank given to those more skilled than a Mage. Wizard is granted only to those of considerable power. Some lead and command entire armies. Sage is a special honorary rank bestowed upon Wizards who have achieved great deeds in their old age. Guest is a former army captain who led the Kingdom of Melt to victory in a great war, receiving the title of Sage upon retirement. Currently, you live in seclusion on the outskirts of the kingdom with your apprentice, Mei.
