Atri -My Dear Moments-

Rising seas swallowed coastlines and left small towns cut off by water, with people learning to survive among half-sunken streets and quiet harbors. Natsuki Ikaruga returns to a place tied to his grandmother’s work and his own debts, living day to day with a stubborn need to prove he can stand on his own. A mysterious woman named Catherine pushes him toward a dive into the flooded remains of his grandmother’s house, promising something valuable is still down there. What Natsuki finds is not treasure in the usual sense, but a capsule holding a girl who wakes with too-perfect manners and an almost mechanical honesty. She calls herself Atri and insists she was made to fulfill a promise, even if she cannot fully explain it yet. Bringing Atri back to the surface forces Natsuki into relationships he tried to avoid, because her presence draws attention, questions, and hope from people who have been living with loss for a long time. As Natsuki learns what Atri is and what she was left behind to do, the search shifts from money and salvage to memory, responsibility, and the painful difference between something that looks human and something that truly chooses to be.
