The Demon Lord's Lewd Crest. Any woman who is has such witchcraft engraved into her body... shall become a slut that indulges in sex with men... and converts their cumforce to energy for funneling to the Demon Lord. Bishop Maria and adherent Flam have made their way to the Mareinu Kingdom following a prophecy that the Demon Lord's Lewd Crest will appear there. With the assistance of Princess Tiara they being their investigation. It would seem that the people of Mareinu Kingdom have a distinctly lacking sense of virtue... Knight, flower shop owner, sister of the faith, tavern girl, general store clerk, elf, adventurer's guild receptionist... etc. In their search for clues, Maria and Flam catch a glimpse of the lewd and libidinous daily lives of various woman throughout the kingdom. While Maria may have a cute face, it would seem they're actually packing a massive and formidable cannon in their pants. While Maria uses the woman along the way like cumdumps to satiate their lust... it turns out that the Demon Lord's memento has already manifested... and the woman turned slut is already out and about draining men of their cumforce......
