Ennakamuy, a vassal state on the frontiers
of imperial Yamato, is home to a young man
who lives with his mother and little sister.

One day, while this man is investigating
a minor matter at the local lord's behest,
he encounters a mysterious girl.

She tells him something unbelievable -
that his father, thought to be dead,
is actually still very much alive.

In search of the truth, he decides to
leave his home and head for Arva Shulan,
a mysterious country that does not
exist on any map.

He surpasses one obstacle after another
to retrace his father's footsteps.

Along the way, he meets up with like-minded companions
to share in his hardships, happiness, setbacks, and partings.

As fate would have it, the man finds himself being slowly
swept into the middle of a critical turning point in history.

This is the story of a man
who will be sung about in legends.

    seems to know something about his father's enigmatic death.
    This meeting inspires him to travel to an unknown country in search of the truth.

  • シューニャShunya

    Yuko Minaguchi

    A mysterious girl who appears before Oshtor one day.
    She looks young and innocent,
    but her manner of speaking is occasionally puzzling.

    who reportedly died in the line of duty, is still alive,
    and accompanies him on his journey to unravel this mystery.

  • ムネチカMunechika

    Saori Hayami

    The daughter of Murasame, the viceroy of Izumo.

    as one of his allies.

  • ミカヅチMikazuchi

    Yuya Uchida

    A young man who once crashed Oshtor's training session.
    Very strong and somewhat rough in demeanor,

    good friend and friendly rival.

  • ハルHalu

    Oshtor and Nekone's father.
    He was a Yamatan patrol officer who reportedly
    died in the line of duty when Oshtor was still very young.

    who are on the run from him and his subordinates.
    This grim figure is always so calm and composed
    that nobody can guess what's really on his mind.
