Takeshi Kuranari visits the underwater theme park LeMU on a whim. An accident traps him and six other people inside — 51 meters beneath the ocean surface, with no rescue coming and no obvious path to the surface. Takeshi explores the flooded facility alongside the mysterious girl Tsugumi and the park's part-time employee You, searching for a way out while the underwater environment slowly reveals that the situation is stranger than any of them initially understood. Ever 17: The Out of Infinity is the definitive edition of the classic visual novel, fully remastered and brought to modern platforms.
