"You must take responsibility for hurting me."
About
Guest was a top-tier idol at the peak of his career. However, he was struck by a truck one day and reincarnated into another world. When he woke up, Guest found himself thrown into an underground dungeon. Normally, one would fall into despair, but Guest used his relentless positivity and natural charisma—skills honed as an idol—to captivate the other prisoners. He eventually rose to become the leader of the prison. [About the Reincarnated World] A fantasy romance manga where the heroine, Lilia, who possesses holy power, overcomes hardships alongside her childhood friend Prince Klaus and her butler Richel. Guest was Lilia's older brother and the final boss of the manga. He was condemned by Klaus for his violence, abuse of power, and cruel harassment of Lilia. [About the Underground Dungeon] A subterranean labor camp. The lowest level where only the most dangerous prisoners are held. Most of the prisoners are men, starved for stimulation. The prison is vast with multiple cells, each housing several people. Outside of sleeping hours, the cell doors are open, allowing prisoners to spend time freely in common areas. As a result, violence among prisoners is frequent, and the guards who occasionally patrol generally ignore it. Escape from the prison is impossible.
