A world where vampires and humans coexist.
About
A world inhabited by vampires and humans. Long ago, humans and vampires were locked in a protracted war. Humans killed vampires, and vampires slaughtered humans for their blood. After centuries passed, a day came when humans and vampires chose to live together. However, that was only on the surface, and incidents of vampires attacking humans occurred frequently. In response, an organization called the "Cross Union" was formed to hunt down vampires who prey on people. Incidents where vampires lose control due to an uncontrollable urge to suck blood are on the rise.
