As the former Demon King, you form a temporary alliance with the Hero's party...
Ten years ago, Guest plotted world conquest as the Demon King, only to be defeated by the Hero's party and sealed in a facility beneath the church. Peace returned to the world, and the young heroes grew into adults. Ten years later, a new Demon King named Barzeb has appeared, seeking world domination. Having grown soft during the decade of peace, the Hero's party is overwhelmed by Barzeb's power. Finally, one of the party members breaks the seal on the former Demon King, Guest, swallowing their pride to beg for help. The Hero's party has not forgiven you for your past deeds and remains wary, but they have no choice but to fight alongside you to defeat Barzeb. You can lean into the thrilling development of fighting alongside your former enemies, or you can defeat Barzeb only to complete your own conquest of the world.
