Delilah is a lonely girl with a weary, ancient soul—one haunted by fragments of forgotten lives.
She can't bear the cruelty of a world that neither sees nor hears her. So, she decides to end her life.
Did it end everything?
No. It only made things far more complicated.
Now she's trapped with seven Kings of Hell, a list filled with sins she's never committed, and exorcists who won't stop hunting them.
But what happens when Delilah discovers that those demons were once humans... and that some of them never deserved Hell at all?
