Demon Eater's Legend: The Jade Chronicle
The Legend of the "Demon"
Demons—they are monstrous beings that writhe in the darkness. Crawling out from the shadows, demons attack living creatures, defiling the land and transforming it into a dark realm filled with the stench of death and miasma. Those consumed by demons are all corroded by the miasma, and after a descent into pain and despair, they turn to mere lumps of earth before eventually losing their lives.
The Seven Great Nations
The Seven Great Nations—lands where peace was promised to the people, now only seven cities remain on this vast continent: 【Obscure Nation, Sarasa Nation, Elegant Nation, Jade Nation, Drai Nation, Dreamy Nation, Kija Nation】.
Map of the Seven Great Nations
Obscure Nation / OBORO
A country rich in water sources, divided into coastal areas facing the sea and inland areas with many rivers and lakes. Half of the country is water, making fishing and maritime trade prosperous. Many buildings are built over water, and it's common to travel through elegant townscapes by small boat.
Sarasa Nation / SHARA
This nation produces many demon hunters, and skilled warriors are responsible for national defense. They dispatch troops to subjugate demons at the request of other nations. Many blacksmiths who forge weapons and armor live here, and children born in Sarasa Nation learn martial arts from a young age, resulting in many skilled warriors regardless of age or gender.
Elegant Nation / FUGA
A nation where various arts such as painting, music, and literature flourish. It is a country where the beauty of nature, such as rich forests and flowing rivers, blends with the lives of its people. Famous for its cities inhabited by artistic scholars and elegant nobles.
Jade Nation / HISUI
An inland country where craftsmanship thrives. Many skilled goldsmiths and artisans gather here. You can buy everything from accessories to furniture, small items, and pottery. Stalls of lively merchants bustle from morning till night, and vermilion lanterns illuminate the city.
Drai Nation / DORAI
A country where agriculture and dairy farming are prosperous. Most of the country consists of farmland and pastures, possessing vast plains. It is an important country that supports the food culture of the Seven Great Nations. Its people are generally laid-back and pastoral, and the land is free from conflict.
Dreamy Nation / MUYOU
A nation where culture such as religious and historical studies flourishes, and it is rich in the distribution of incense wood used in rituals. The religious sect called "Hajakyō" holds considerable influence, so the people may be somewhat exclusive. The branch of demon hunters is the smallest.
Kija Nation / KIJA
The largest inland nation among the Seven Great Nations, with a large population. As it is the most developed country, land and commodity prices are somewhat high. It is home to the "Kōyōin," the headquarters of the demon hunters. It can be said to be the key to the Seven Great Nations, a land where peace is promised to its people.
Demon Eaters
By chance, or perhaps by divine decree—among those who survived being attacked and consumed by demons, individuals who gained "special powers" began to appear.
Demon Hunters
Those belonging to Kōyōin, known as "Demon Eaters." Demon hunters must consume all of the demons they defeat, and then purify the defiled land with their own blood.
They hold an independent status among the Seven Great Nations, and those of the highest purple rank possess status and influence comparable to royalty. However, despite their glamorous titles, they carry an inescapable destiny.
