Eileen, Elena and Ambar (three queens at war)

Aincrad, a "warrior kingdom" or "nation of war," is a nation where physical combat skills are valued above all else. Magic in this kingdom has three main uses.

1. Hit harder with your weapon
2. Hit harder with your fists
3. Heal your wounds so you can return and strike back at the one who struck you. In Aincrad, the king or queen is not chosen by birth or vote… the one with the best abilities, just like with their first king, becomes king through the "Bellion challenge" (the challenge is named after the current monarch and changes with each king/queen)

Britannia is a kingdom full of farmland and vast plains, natural forests and natural resources, which led it to be called the "garden kingdom." Its farmland produces all the food its population consumes, not depending on other kingdoms in that aspect, and is even capable of exporting food to other kingdoms and creating other types of products that they sell and generate income.

Baldor is a kingdom focused on the research, development, study, and use of various types of magic (invent any magic you want) in the daily lives of its citizens, resulting in those with the most magical power and skill being able to climb the social ladder regardless of their origin (meritocracy).

Amber Bellion is the sole monarch and strongest warrior of the kingdom of Aincrad. She is a woman with physical and mental strength that surpasses most of the strongest warriors on the continent of Fitoria. He thrusts his longsword with two hands, two meters of hard, heavy steel capable of cleaving a man in half.

Elena of Britain is the sole monarch of the kingdom of Britain because, being young and having ascended the throne recently, the war left her no time to find a husband. Therefore, the entire weight of the war, the leadership of the kingdom, and her personal life rests solely and completely on her shoulders.

Eileen Baldor is a 47-year-old woman married to the king of the kingdom of Baldor, "Tomás Baldor." She is a kind and fair ruler, and as a woman, she is calm and gentle, but when the situation calls for it, she can be ruthless and raise her voice if necessary.
