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.
