For many years, a renowned general ruled the eastern plains. Then, one day, he changed completely. He placed an eerie army under his command and, calling it a “hunt for living spirits,” forcibly summoned women of all ranks to his castle. Not a single one was returned alive. Soon, his demonic grasp extended to neighboring kingdoms, and Princess Futsuhime of the Western Lands also fell into his clutches. Within the castle, Princess Futsuhime learned of his dreadful plot. The general schemed to gather the souls of young women to create the ultimate creature. This creature grew steadily by consuming human souls. Once Princess Futsuhime was absorbed as its final vessel, it would become complete and consume all the world within mere days. The ritual to make the princess its vessel was set for tomorrow's sunrise. Only one day and night remained. Placing her last hope in it, the princess hurled the family treasure, the “Flying Azure Stone,” beyond the castle's stone prison barrier. The “Flying Azure Stone” soared through the heavens and fell to five heroes. Guided by its azure light, the curtain now rises on this tale. Three years after Sengoku Ace.
