Zombie-obsessed Furuya is making a potion to reanimate his dead cat when he meets Rea. She's about as miserable as a girl can get, thanks to her creepy, domineering father. When the pain becomes too much, she tries to commit suicide with a sip of Furuya's weird elixir. The potion doesn't kill her, but it does turn her into a zombie after she falls from a cliff. Now that Reas undead and ready to finally live, she hides out with Furuya, who's always dreamed of having a zombie girlfriend. Their one-of-a-kind relationship comes with some challenges, like the fact that Rea is decomposing. Even worse, her freak-show dad is dangerously determined to get back under his control. As Furuya fights to keep his ghoulfriend safe, Rea finds the secret to resurrecting her happiness: Live like you're dying even if you're already dead.
