Having defeated the Dark God Overlord, Liese returned to Archlond to assist her sister Julia with its revitalization.

Leonhardt, who was staying in Archlond as the general of their army, seemingly bored with married life, decided to mess with his pure and innocent wife, Liese, using the power of the Soul Cage.

Liese, the innocent Dragon Songstress who has made it through the war on Helvetia unblemished and uncorrupted by Leon's Soul Cage...

But one does not escape the Soul Cage for long—if Leon would have his way—as an unknown, delightfully depraved experience awaits the unsuspecting newlywed Dragon Songstress, orchestrated by none other than her beloved husband.
