Viren Kuru is a reaper with 6 souls who comes to the Exorcist Association to get a Reaper license. To get it, he has to go through an interview and test. The recruitment officer doubts he actually has 6 souls, so he decides to test him right away. During the test, Viren will need to enter the grave realm and fight the Restless, the monsters that spawn in a disturbed grave. During this test, Viren will have the chance to show just how powerful he really is.
