Taito Masaki is making his way to the island nation of Grazia, so as to find out what happened to his father, who left years ago in search of a dream. On the way there via boat, Taito gets involved in hunting down a missing soldier who's become maddened by an experimental drug called "Rabbit". This marks the beginning of Taito discovering the truth behind his father, "Rabbit", & how they both relate to Klaus Daggats, Grazia's "God of Fighting", who lives in his own Spiral Palace, filled with warriors from around the world.
