Ghost Hunting System

When the plague descended on the earth, it affected the entire population.

The plague scattered around the world, until living creatures began to deteriorate.

The population decreased, day by day until a year later did the plague was solved.

However, as soon as humanity thought the pandemic was over, living creatures who died from the plague become powerful ghosts with negative sentiment.

They began recking havoc, everywhere. Humanity was hopeless.

But certain people who were infected and survived surprisingly gain abilities.

Hence they become the hero of the society, the Ghost Hunters!
