Jack Oshinumi is a young man of English descent who is forced to reside in Hokkaido after contracting serious illness, much to his chagrin. With his mind more concerned about his studies than his health, Jack finds himself at odds with his family around him. All he wants is to return to school, return to Tokyo, and being an ordinary Japanese boy, and that's all that matters to him.

As soon as he moves in, however, Jack begins to see strange beings emerge in not just his dreams, but even in the real world. One day, Jack encounters a strange man named Rin Funo, who looks similar to one of those beings he saw in his dreams. Rin, a family friend to his cousins, give Jack a certain pendant. Before long, Jack finds himself amidst several parties interested in that pendant for their own malicious purposes - parties from the realm of the fae, Nymphidia.

When the pendant falls into the hands of another, Jack must leave Hokkaido, and embark on a journey within Nymphidia. This journey will make him realize not just his purpose, but the significance of his heritage.
