Istoria of Pleasure

One of the seven deadly sins, the Demon King of Lust, has been resurrected.
The weakening magic he has cast has rendered you, the hero, unable to even wield a sword. Only three companions blessed by the hero:
Saint Kazane, Princess Knight Noel, and Mage Kanon can fight.

However, the Demon King has branded a lewd curse, the "Mark of Lust," into their wombs.
As they fight, resisting the throbbing pain, the Prince of Greed, who escaped the magic, approaches them.
The prince, who has been eyeing them since the past, begins to move to make them his own.
