An unexpected journey leads Constantine McCallister to the island nation of Hokkaido as his uncle, a Prelate to the Vatican, investigates the strange and potentially supernatural disappearance of a group of Catholic monks. What promises to be a season of refining his skills as a painter in the beautiful Hokkaido landscape, Constantine's idyllic repose turns into a fight for his life when he offends the privileged son of a clan boss. Constantine doesn't know how to fight, but when the bookish Star-Lu and her eccentric grandfather enter his life, Constantine learns that he might have been preparing for battle his entire life, that is, so long as he can live long enough to save himself, his uncle, and the beautiful Star-Lu.
