Michiru Kita is a girl with an unusual ability: when she notices dark rings around the necks of two of her classmates - rings that are invisible to any normal person - she knows that their lives are at risk. She decides to approach them, in order to warn them or help them in some way, but soon discovers that there is more to the two boys than even her eyes could see. They are zombies, working for the mysterious company known as Z-Loan in order to pay their debts. And so Michiru finds herself helping the short-tempered Chika and the cold, indifferent Shito in ways that she'd never have imagined - fighting off illegal zombies to collect their bounties! But these illegal zombies, usually very basic and driven by instinct, seem to be getting more intelligent each time...
These enthrilling manga share a very similar plot, as they both revolve around demons (respectively called Freaks & Tsumitsuki) which feed on a person's negative feelings (sins, guilt, stress, murderous intents, perversions, etc) and, as they grow, possess those people's body, soul and mind, which leads to that person's violent death.Asagi Nanami & Kuroe are both mysterious, at times eerie guys who hunt those creatures with their supernatural powers.Both manga are dark, unique, and great.
