The demon lord son live as a exorcist

Luciel, the heir to the Demon King, finds himself stripped of his power, wandering the mortal world in search of a way to reclaim his strength. Frustrated and hungry, he stumbles upon the Central Library, a vast, quiet place filled with human knowledge. Determined to find a way back to his former glory, Luciel dives into the world of human language, struggling at first to make sense of the foreign symbols and words.



As days turn into weeks, Luciel perseveres, gradually mastering the language and uncovering the intricacies of human history, science, and culture. But it’s when he accidentally discovers a hidden, ancient book on exorcists and forbidden knowledge that his world truly shifts. The book reveals the existence of exorcists—warriors trained to hunt and destroy beings like Luciel—and hidden wars fought in the shadows of the mortal world.



Realizing that the human world is far more complex and dangerous than he initially thought, Luciel’s curiosity and ambition are ignited. Armed with new knowledge, he begins to see the world through a different lens, one filled with opportunity and threats. The game has changed, and Luciel is now ready to play it on his own terms.
