The black ring. When it appears around a person’s neck, it is the sign that they will soon die. Invisible to most, only those with the special ability of the Shinigami Eye can see it and thus predict the future.
One such possessor is Michiru Kita, a downtrodden and soft spoken orphan girl who is used by everyone and has no real will of her own. Her spectacles block the sight of the black rings, but by simply removing them she is cursed with the knowledge of which people are close to death.
A chance encounter with two mysterious, seemingly-money grabbing boys introduces Michiru to the enigmatic Zombie-Loan loan office, a secretive business that offers deals that should not be offered or even possible, never mind the fact that the abomination of these deals should probably not even exist! These two boys, Chika Akatsuki and Shito Tachibana are both marked (thanks to an unfortunate accident on a bridge) and should be dead – but yet they aren’t. And their rather ghoulish habit of switching hands which contain spiritual weapons in the form of a gun for Shito and a katana for Chika are more than clue enough that there is something far more to their tragic story than what first meets the eye.
Dragged into joining their bedraggled group in order to assist with identifying monsters with the black ring, beings who should be dead but who are instead living as the undead and feeding on flesh while acting only on desire, Michiru is about to find out that her life is going to all of a sudden get a whole lot more complicated – and very quickly at that!
