Zombie-Loan

Do you know when you’ll die? Michiru Kita does-she can see a "ring of death" around people’s necks, and the darker it is, the closer they are to the end. One day, she spots two classmates, Chika Akatsuki and Shito Tachibana, with rings so black they should already be dead. When she tries to warn them, she discovers their secret: they "are" dead, kept alive only by a deal with Zombie-Loan, a shady organization. The catch? To repay their debt, they have to hunt zombies. And when they find out about Michiru’s "Shinigami Eyes," they pull her into their dangerous, undead world.
