Nina discovered him lying unconscious in the middle of a road in the desert area of the eastern continent.
    What his clan is and where he is from are unknown.
    He has "Dragon Eyes," a feature considered extremely unusual in this world. There are various legends about those who posess "Dragon Eyes" - some say that they will rule the world, some that they will bring disaster and ruin, and so on. It's difficult, however, to see Ryu as such a mysterious being, from the way he usually acts.

    The founder of the Fou Empire, in the west. Its first emperor.
    With his supernatural power, he managed to unite the entire western continent in a single generation.
    After that, he supposedly predicted that he would return several hundred years later, then vanished.
    Although he outwardly appeared to be a man in his twenties, he possessed such wisdom and dignity that he seemed almost a mystery beyond human understanding, and after his death, he was deified and became known as the "God-Emperor."

    The princess of Wyndia, a kingdom that is part of the Eastern Alliance.
Wing Clan.
    Meets Ryu while on a journey, searching for her missing sister. Perhaps because of her delicate, high-class upbringing, she has a somewhat childish side to her; bluntly put, she's unreliable. She greatly admires her beautiful, levelheaded sister.

    The young chief of the Furen Clan, a group affiliated with the Eastern Alliance.
Along with Nina, he sets out on a search for Princess Elina, who had been a friend of his since childhood.
    Although one of the warlike Furen Clan, he forces himself to keep cool and calm as much as possible.
    The sense of responsibility he has as the chief of his clan leads him to act this way, but sometimes it gets to be too much and his anger explodes.

    Although a commoner by birth, she was recruited by a general who noticed and appreciated the strength of her magic power.
    Proficient at the use of a magic-powered gun, she has a reputation as a cool-headed, trustworthy soldier. She is currently part of a search party located in neutral territory in the east.

    Out of a job once the war ended, he wandered aimlessly, doing nothing in particular. After a certain incident, he is assigned to keep an eye on the main character and his companions.
    Although extremely reticent and aloof, he is also quite dependable. A drinker.

    He wears armor that protects him from hexes, sealing him in completely.
    Since he never takes off the armor even to eat or sleep, his true appearance and clan are unknown.
The way he acts is somewhat suspicious, saying things that are completely out of place, laughing at inappropriate moments, etc.
    He meets the main character in a place contaminated by a hex and then joins him for some reason.
