This world

Valistan

A union including neighboring city-states. Its capital is Novastria.
The country is reasonably large and blessed with fertile land and natural resources.
The current king, Aldric, has the foresight to appoint a female knight order, the Flame Lily. This led to an increase in power, the nation prospered, and the people were enthusiastic about the king and the women’s order.

Flame Lily Order

A group of women seeking liberation from the unreasonableness and oppression of the world have gathered under the leadership of their leader, Ariana Valeria, as a group of mercenaries.
Ariana accidentally discovered a method to keep the ether in the body, and spread armor and clothing using this concept to the members of the group. With the help of Ariana’s armor, some members of the group were able to develop their etheric abilities. The Veiled Armor, later developed by the blacksmith Volgan, further enhanced the ethereal effect.
However, these armors had the disadvantage that they tended to expose the chest and lower abdomen area. Although the ethereal effect made their defensive capabilities unproblematic, they were criticized for making a show of the female body, and were derided as a whore mercenary band. Their eccentric design was based on autonomous magical determination and was uncontrollable even by Ariana herself.
However, such criticism gradually subsided after they achieved numerous successes on the battlefield, and they became the object of admiration among women. Townswomen began to appear wearing clothing that imitated the Flame Lily.
Ariana’s band of mercenaries gained the trust of King Aldric of Valistain and became the Royal Order.

Senate

An advisory body that helps the king make decisions. An organization older than the royal family.
It has its own military and intelligence services.
It is concerned that its own influence over King Aldric and his female order is waning and that it will not be able to control the king, so it is trying to strategize against him. Their private armies use vision-restricted ether-enhanced armor.

Karadon Empire

A empire hostile to Varistan. It has the largest territory in the world. Most of its land is arid.
Secretly aligned with the Senate of Varistan, they have acquired several suits of veiled armor from the Senate and are researching them for use in their own war efforts.
The female general, Vera Zafira, has accidentally shown a high affinity for one suit of veiled armor and has put it into practice.

Xenos Republic

A country with advanced research and development in science and magical engineering. They are developing machines and tools that utilize the ether. It is hostile to Varistan because of its desire to exploit Varistan’s rich resources. It has close relations with the Senate and is allied with the Caradon Empire.
They have captured the Flame Lily and are developing a device to weaken and restrain them in order to study their mighty armor and the bodies of their wearers.

Leonia Kingdom

A small country in the tropics. Many brave and proud warriors. They have special forces that use the ether. The Kingdom of Leonia is a male-centered society based on their religious beliefs, and has adopted a system of polygamy called the harem.
The King of Leonia despises the Flame Lily as prostitutes and heretics, and has vowed to destroy them.

Demonic realm

The world has many untouched lands for humans.
Goblins, orcs, ogres, dragons, and other creatures inhabit these savage lands, and if an impotent human carelessly approaches them, he or she may be killed.
The human and monster realms are strangely balanced, and there are no large-scale wars over territory, with only the occasional daredevil venturing deep into the other’s territory and causing trouble.

Goblin: Although they are considered a minor threat among demons, ordinary humans are no match for them in strength. Some individuals with extremely high intelligence have been confirmed. They have a habit of kidnapping human women.
Dragon: A monster with the power to destroy a country on its own. Fortunately, for some reason, there is no record of it ever attacking a major city.
There are countless unknown demons…
