The journeys of a priest and a young warrior unexpectedly converge when they both save a novice seer from a vicious beast during their individual quests to visit the oracle. Both travelers are in search of answers to locate someone of great importance, but their path to the oracle's abode is riddled with difficulties. This sets the stage for a magnificent saga featuring humans, dragons, phoenixes, and an ancient kingdom embroiled in a fierce uprising.
As a side note, Volume 1 contains a self-contained chapter called "Seiju no Kajitsu," which chronicles a young witch's mission to procure the legendary "fruit of the holy tree" to save her beloved fiancé.
Furthermore, the series concludes with Volume 4, but fans can indulge in two supplementary stories concerning the main protagonists in Volume 5.
