When the Rain Apocalypse descends, Nina Grant, who has experienced Rebirth, rejects the amplification Superpower that caused her death in her past life, and resolutely chooses the seemingly useless Shrinking Superpower. She is fully aware of the danger of "High profile attracts trouble" in the apocalypse, secretly rents a villa, stockpiles sufficient supplies, shrinks the entire building and survival resources into a palm-sized Miniature Fortress, creating an absolutely safe hidden space. Meanwhile, her younger sister Wendy Grant seizes the amplification Superpower, becomes obsessed with pleasing her lover Chase Lowe, and turns into a "mobile granary" for Chase's family and greedy neighbors. She is eventually ruthlessly abandoned after Superpower Overdraw, deserted by all around her.
