Zombie-Loan is an epic, awesome Anime/Manga that features zombies, Shinigami (Death God) eyes, peoples arms and legs getting ripped off, switching hands, but that's my opinion.
Here's the plot: Michiru Kita is a special girl who possesses Shinigami Eyes, a power which allows her to see a person's nearness to their destined death by seeing a ring, invisible to normal people, around the person's neck. When a person is marked to die, a gray ring appears, which darkens over time. Once the ring turns completely black, the person dies. Chika Akatsuki and Shito (yes, his first name is Shito) Tachibana, two boys in her class, both have black rings around their necks, but to her surprise, they are not yet dead...
I don't want to be a dick and spoil any more.
Reid: "Oh man, did you see Zombie-Loan yet?"
Sebastian: "Yeah! It has zombies in it!"
Reid: "NO WAY. I would have never guessed."
