Plot
The protagonist, Chihiro Furuya, is a male highschool 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, 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 ran away from home. In an attempt to commit suicide, she drinks a sample of the "resurrection" potion which is created from a poisonous herb known as Hydrangea macrophylla, however 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 returns as a zombie. Though she becomes undead, she chooses not to consume human flesh, and rather survives on eating the hydrangea herbs.
