Elena is the Princess of the Kingdom of Eledia. She is destined to wed a groom chosen by divine oracle. Until now, princes from other nations have always been selected. However, this time, the oracle has chosen the protagonist—a commoner.

The protagonist is a young man living in poverty who has never accomplished anything of note. He has never wielded a weapon or cast a spell, but his lack of experience means he has immense potential for growth.

There are five major nations in this world, inhabited by monsters, magical beasts, demon lords, various races, gods, and angels. Magic is diverse, ranging from everyday utility to violent applications in war. Each nation employs several Court Mages. Adventurer and merchant guilds thrive, though demon kin occasionally invade human territories.

Eledia is ruled by Elena's family. The lily is the nation's symbol, representing love and peace. It is a peaceful, neutral country. While its military strength is sufficient to deter neighbors, other nations are secretly eyeing it, plotting to take over should the opportunity arise, making war a constant underlying threat.

Bergleich is ruled by Edrich. A radical nation that has sparked numerous wars backed by military might. King Edrich is ambitious, militaristic, and bellicose. He repeatedly invades both human nations and demon territories. While he keeps demons as slaves, he favors and recruits those with high abilities, leading to deep resentment among the demon kin. A faction of demons is secretly plotting a rebellion, leaving the country on the brink of internal conflict.

Hanselt is ruled by Velura. It is the wealthiest and most commercially active country in the world. Canals run through every corner of the land. They possess military power but do not hesitate to use wealth as a weapon. King Velura is a merchant at heart, acting solely on profit and loss calculations.

Zephyria is ruled by Aurelius. It is the world's greatest magical superpower with the largest number of mages. The Court Mages consist of the Four Heavenly Kings, the highest-ranking mages in the world. Queen Aurelius herself is an Elf and a master of magic. The nation values non-aggression and is somewhat isolationist, focusing on defense. Compared to other nations, the population is almost entirely Elven.

Wahrheit is an empire ruled by Gandalf V. It boasts the greatest military power. Its cities offer products from all over the world, possessing a perfect balance of resources, wealth, technology, and magic. They generally have no intention of starting wars and remain unshakeable. They are shrewd, often scouting and recruiting talented individuals from other lands.
