Even though he was born to parents of the most powerful classes, Arel discovers that he has no class at all! This hasn’t stopped him from working his hardest, however, and developing in his own way. He ventures to the sword city of Bresgia to take part in a guild battle.
His efforts place his new guild, Dragon Fang, among the best, and afterwards Arel learns of the city’s most prestigious tournament, the Sword God Cup. It’s a battle where the strongest make their names, and so Arel heads into the city’s giant underground labyrinth to sharpen his skills.
