For example, one of the chapter/arc from Franken Fran about Zombie;
Spoiler (mouse over to view)
which tell us that the zombie is a disease that make the human became like zombie, but they are still alive, they still could think and feel, but they cannot control their body and forcefully must watch themselves attacking other people and infect them with the same disease, and also watch alot of them being killed by the people that "have not infected yet but thought they are already dead so its okay to shoot them in their head"
So, any sugggestion? More like Girls' Day Out of the Living Dead, Wake Up Deadman, The Living Dead!
But maybe not really like Kore wa Zombie desu ka?, Zombie-Loan
