"Since the moment Jawhwan entered Abyss, the surprises haven't stopped. Shortly after accidentally devouring a god and becoming her agent, he runs into a familiar face he never expected to see again--Yunhwan! But before Jaehwan can call out to his old friend from the Tower days, Yunhwan is dragged away in chains. And in a cruel twist of fate, Jaehwan's search for his ex-comrade leads him to a structure he knows all too well--a Nightmare Tower."--Provided by publisher.
