Sankarea: Undying Love

Since he was little, Chihiro has felt an unusual emotional connection to zombie movies. It's not that he feels bad for the survivors—instead he fantasizes about comforting the poor undead girls they slaughter! When his beloved pet passes away, he decides to brew up a resurrection potion in secret. But he's discovered by popular girl and local heiress Sanka Rea, whose life isn't as perfect as it seems ... and Furuya suggests that she could serve as a test subject! (Source: Kodansha USA)
