ATRI -My Dear Moments- is a single-player visual novel set in a near future where rising seas have submerged much of civilization. Returning to his grandmother’s coastal home, Natsuki searches the underwater ruins of her laboratory for a rumored treasure. Instead, he finds Atri, a robot girl who asks to help him as he tries to rebuild his future. The flooded setting and the relationship between the boy and the mysterious machine frame the game’s story.
Its documented format is adventure and casual, with single-player as the listed play mode. The premise centers on a salvage expedition, Atri’s lost memories and her former master’s final order; the supplied description does not specify hands-on salvage systems or other detailed mechanics.
The emotional contrast is central to the setup: Atri is a robot, yet her appearance and expressive personality make her seem human, while Natsuki carries the consequences of an earlier accident and a difficult return home. Their summer unfolds in a town gradually overtaken by the ocean, alongside childhood friend Minamo and other local characters. The listed single-player format gives player-count information its context, while the game’s defining appeal is its individual story rather than a shared-session experience.
