School:Sanka Girls' High School
Rea steals and drinks some of the zombie potion made by Chihiro in an attempt to commit suicide because of the sheltered life she lives. She fails in the attempt but she resurrects as zombie when she accidentally falls of a cliff and dies. As a zombie, she lives together with Chihiro in order to know how it feels to become free from her father's chains.
Rea is friendly with everyone at the shrine, including Darin despite her intentions to use Rea as a research subject. She calls Mero by Mero-Chan similar to that of Mero's mother which causes Mero great discomfort at first. Similarly, she calls Darin with the -Chan suffix to Darin's discontent.
She likes Chihiro and feels like she is bothering or interrupting Chihiro and Ranko's relationship. She seems to understand Bābu. She's also physically strong as her body is no longer restrained by her brain as a result of her death.
