Our protagonist, Chihiro Furuya, is a zombie crazed otaku that plans to revive his recently deceased pet cat, Babu, using a resurrection potion recipe he found in his closet. Meanwhile, a rich girl by the name of Rea Sanka (Titular Character...) wishes to die and be reborn as a new person, free from her oppressive father. When she drinks a bit of the potion and happens to die, she suddenly stands back up as... a Zombie Girlfriend.

Seriously, talk about crossing the line twice. However, this is proving to be a very nice manga so far, and I'm the kind of guy that can't play Resident Evil solely because zombies creep the sh*t out of me. >.>;
There's also an anime adaptation that just started at the time of this post, which seems to be an Adaptation Expansion, considering there's a lot in the anime that only got a passing mention in the manga. Give this series a look sometime. It's pretty interesting.

Best necrophilia comedy I've ever read
