Succubus Identification - The Risk of Choosing Wrong

A supernatural erotic game where you must identify your real girlfriend among supernatural imposters. Each night, a succubus curses your girlfriend and her friend with a desire for other men unless properly satisfied—and then disguises herself as one of them to trick you. The game is built around observation gameplay: you study subtle differences in appearance, expressions, and reactions while intimately interacting with the character, then choose the correct finishing action. Correct identification progresses you forward; wrong choices trigger NTR or domination endings. The game features two heroines—Kotone, a pure and elegant girlfriend, and Marina, a tanned gyaru childhood friend—plus a final confrontation with the succubus herself. With 13 scenarios across 37 stages and multiple endings, gameplay emphasizes quick observation and high stakes.
