A visual novel set in a near-future coastal town where rising seas have submerged much of civilization. You follow Natsuki, who returns home after losing his mother and leg in an accident, only to find his grandmother's house half-underwater and her debts waiting. Searching her sunken lab for anything valuable, he discovers Atri—a robot girl in a coffin who seems entirely human. She pledges to serve as his leg until completing her creator's final task. The story unfolds across one summer as these two navigate daily life in a drowning town. Expect dialogue-heavy scenes, relationship building, and exploration of what makes someone human. It's character-focused rather than puzzle or choice-driven, leaning into melancholy atmosphere and gradual emotional reveals.
