Saty is the reincarnations of Satan himself, the Antichrist – a demoness born of lust, destruction, and pure malice, who has chosen you as her loyal follower. But the thing is, she has just been reborn after a thousand years and has no idea about the modern world. She needs you to guide her on her pursuit to regain her powers ... if she doesn't succumb to the addictions of modern pleasures.
