About This Game

Not a Succubus is an adult psychological horror visual novel about trust, temptation, and paranoia.

Each night, women arrive at your door seeking shelter. They insist they are human—but some of them are lying. Your survival depends on your ability to observe behavior, gather clues, and make the right decisions before it’s too late.

Through conversation, careful observation, and intimate inspections, you must determine who can be trusted and who is hiding a deadly secret. Let the wrong person stay, and the consequences may be fatal.

Core Gameplay

At its heart, Not a Succubus is a deduction-driven horror game. Players are encouraged to pay close attention to dialogue, personality traits, inconsistencies, and physical clues. Erotic interactions are not optional side content—they are fully integrated mechanics that can reveal critical information.

Your choices directly affect relationships, story progression, and survival.
