The NOexistenceN of you AND me frames psychological horror around an intimate, uncanny encounter: a mysterious girl appears in the protagonist’s room, and the immediate task is simply to say hello. From that small premise, the game turns toward questions of existence, identity and the nature of the world, presenting its story as an experience to interpret rather than a character introduction built around labels.
Its central interaction is choice-driven. Players navigate hundreds of choices in response to “the girl’s existence,” while the scenarios range from talking with her to making and eating strawberry cake, intervening in a plot involving FONTAINEBLEAU, and journeying through a Silvery Forest to confront a Demon Lord. These sharply contrasting situations give the visual novel a surreal, shifting design; the listed single-player format keeps the focus on an individual path through those decisions and encounters.
The premise also points toward a relationship shaped by conversation and shared moments: the description mentions dating the girl at the world’s end, speaking heart-to-heart, and witnessing an ending with her.
