The protagonist is the executioner of a forbidden prison, specializing in executing "blasphemers" who have been corrupted by the power of the abyss. He is naturally mentally tough and able to withstand crazy ravings. During an execution, he accidentally stole a trace of divinity from the corpse of an ancient god. From then on, he embarked on a thorny road of using a mortal body to harness the power of taboos and fight against unspeakable horrors. He will kill the fallen false gods and reveal the truth that the world was eroded by the "Old Dominators". On the verge of the collapse of his sanity, he will step by step become a new taboo that even the gods tremble at.
