Sankarea episode 1 - If I... Became... a Zombie
Chihiro Furuya is a zombie-loving otaku who becomes depressed when his pet cat, Bub, dies after being hit by a car. Wanting to see him alive again, Chihiro looks into an old manuscript describing resurrection and starts doing experiments in an abandoned building. While there, he encounters a girl named Rea Sanka, who is depressed about how controlled her life is. When Rea learns that Chihiro had been eavesdropping on her secret rants, she decides to help him in his experiments, warming up to the idea that, if she were to become a zombie, Chihiro would take responsibility and look after her.
