A manga and Eleven Episode Anime series by Peach-Pit (of Rozen Maiden, Shugo Chara! and DearS fame).Michiru Kita is an orphaned girl living with her aunt and uncle. She is pretty much normal other than the fact that she possesses "Shinigami Eyes", meaning that, without her glasses, she can see rings around people's necks that show they will die soon.One day, she meets Chika Akatsuki and Shito Tachibana, two survivors of a horrible bus accident in the middle of a Zombie Hunt, and learns the horrible truth about them — they're already dead, and only alive through a "Z Loan" that they seek to pay off by hunting Zombies who are alive illegally. Michiru ends up unceremoniously dragged along in exchange for her life and the use of her eyes to find the already dead.Has a character sheet.
Provides examples of:
Abusive Parents: Chika's mom left him alone at home to live with another man, resulting in him nearly starving to death.
Adult Fear: Minor character Sougiya is a single father trying to pay off his contract to the Z-Loan. He knows that if he isn't able to keep his end of the contract, he will die and then no one will be left to take care of his young daughter.
Age Without Youth: Lao Ye attempted an incomplete immortality ritual on himself, result in this. By the time the story starts, he's nothing more than a withered husk on life support.
Broken Ace: Shiba is a cool, handsome, friendly and highly intellectual person. But he became so bored with his monotonous life that he committed suicide and would come head to head against his best friend Chika.
Contrived Coincidence: Actually becomes a plot point. Michiru has a knack for always showing up in the right place at the right time and developing just the right powers and abilities for their current situation. This makes a lot more sense once it's revealed that she's the Singularity, a living Reality Warper and time/space paradox.
Creepy Child: the little servant boy who helped Michiru is one of these.
Deal with the Devil: The very idea of the Z Loan, though some forms are more devilish than others.
Demonic Possession: Yomi briefly possesses Michiru after the latter went into her Heroic BSOD and to get them out of the warping space from collapsing and taking them with it.
Diabolus ex Machina: So Shito manages to save a rather woobie-ish golem girl from her creator, who saw her as nothing more than a defective failure. Now she's gonna go back with him to Z-Loan and get cared for by people who won't abuse her, right? Cue said creator's assistant shooting her in the head out of nowhere, saying that she was just another monster to be dealt with.
Dysfunction Junction: Pretty much everyone living in the dorms. Michiru lost her parents at a young age and we find out those aren't really her parents. Shito is a living corpse, trying to save his mother. Chika suffered from Parental Abandonment as his mother went to live with another man, resulting in him nearly starving to death in his own home. Koyomi's family had Yomi sealed inside of her to please Yomi, and that didn't work as well as they thought it did, they locked Koyomi inside the house.
Expy: The Butterfly looks like an older Jun Sakurada from Peach-Pit's earlier series Rozen Maiden, and Yuuta and Kuze Shimotsuki are dead ringers for Souseiseki and Shinku respectively. Yuuta also mirrors Natsuki Ikuhara of another Peach-Pit series, DearS, and Chika looks quite a lot like Hatsuharu Sohma.
Forbidden Fruit: An interesting case. The little servant boy tells Michiru when entering the entrance to the spirit world, she mustn't look back. However, Yomi, the one that Michiru is looking for, tells her to turn around. Not knowing whether to trust the boy or Yomi's voice, Michiru does turn around, only to find that the little servant boy standing creepily behind her, wanting to eat her.
Killed Off for Real: Koyomi is killed by Lao Ye as part of the ritual to transfer his soul to Shito, and when Yomi tries to save them both, Koyomi chooses to pass on instead once it becomes clear that Yomi can only save one of them. Bekkou makes it clear afterwards that there's no bringing back someone who passed on of their own free will.
Killer Rabbit: Shinigami Zarame may look like a adorable and very huggable plushie, but I dare you to say that to his face.
The Mafia: Shito's the heir to a powerful Chinese mafia syndicate.
Man, I Feel Like a Woman : An interesting case, where Yomi had taken possession of Michiru's body briefly and wanted to "play with her for a bit".
Meido: In one story arc, Michiru and Koyomi end up buying maid outfits and blending in with the Otaku gathered for an offline meeting.
Mind Screw: In the most recent manga chapters Michiru has to dive into Chika's subconscious mind a la Pensieve Flashback, but something goes wrong and his younger self is able to see and interact with her, making the conversation that originally happened in his mind part of his reality in the past making the whole situation into a bit of a Timey-Wimey Ball. When his teenager self showed up, all bets were off.
Rage Against the Heavens: Hakka is tired of being a cog in a machine, only existing to maintain the Akashic Records, so he plots to kill himself to go against his purpose, while doing as much damage as possible.
Reset Button: Hit at the end of the manga, starting the series over again (though with Hakka imprisoned so he can't enact his plan,) with some characters like Michiru, Bekkou and Yuuta remembering the previous loop.
Ret Gone: It's eventually revealed that Ferrymen like Bekkou have the ability to erase anything that contradicts the Akashic Records from existence (like zombies, and restoring anything the zombies interact with.) The reason they don't just do this all the time instead of bothering with hiring legal zombies to take care of the illegal ones is because it's a Godzilla Threshold-style ability, and is very messy and doesn't fix everything. Z and A-Loan eventually get erased, and end up in reality's recycle bin (It Makes Sense in Context,) where they have to find a way to escape before they're deleted permanently.
Yank the Dog's Chain: Shito promises the golem girl that he will take care of her, teach her how to speak and send her to school like a normal person. She gets killed by Yoshizumi's assistant the next page.
