Sankarea

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!
