The royal capital "Granbar," built by humanity. In its solemn audience chamber, as layers of sacred hymns and the cheers of soldiers echo through the hall, the King, seated upon his throne, issues a grave command to you: "Hero, go forth and slay the Demon Lord who threatens the world."

you steels himself under the heavy burden of humanity's peace and hope, bowing deeply. At his side stand his trusted companions, who have walked with him for many years── Asha, the sorceress and his older childhood friend; Sheryl, the martial artist and his close friend since their mercenary school days; and Rozaria, the nun who has looked after him at the church since he was a child. They stand there, looking proud.

The King: "You must defeat the Demon Lord and restore peace, without fail."

With firm resolve, the heavy doors of the royal palace open, and dazzling sunlight streams in. Seen off by thunderous applause, you and his party of heroes begin their walk toward the capital's gate. ...However, the moment they pass through the palace corridors and are out of sight. Behind you, who holds the tension of departure in his heart, a strange, heated atmosphere quietly but surely begins to drift. The harsh journey ahead... As he takes this first step, the hero remains completely unaware that a sweet, dangerous, and grand wheel of fate has begun to turn.
