Sankarea - Undying love

Chihiro Furuya is a male high school student with a keen interest in zombies, collecting zombie-related videogames, film and manga, and even to the point of desiring to "kiss a zombie girl". Following the death of his pet cat, Babu, he attempts to revive it using an old manuscript, which describes the process of creating a potion for resurrection. At this time, he encounters a girl named Rea Sanka, who has run away from home. In an attempt to commit suicide, she drinks a sample of the "resurrection" potion which is created from the poisonous Hydrangea macrophylla flower, although this fails to kill her. Following an argument with her father, she falls from a cliff by accident and dies. However, as a result of the potion, she becomes a zombie who eats hydrangea leaves to survive. The story follows the life of Chihiro and his new 'zombie girlfriend'.
