In the Hell of Violence, Ja-hong is tried for beating Soo-hong when they were younger while the latter was suffering from malnutrition. The trio pass through the Hells of Injustice and Betrayal without trial.

He is saved by Gang-Rim on Soo-hong's request after the latter agreed to cooperate. Dong-Yeon tips off Soo-hong's mother on the location of his body and attempts suicide. Gang-rim foils an attempt by Soo-hong to kill Dong-yeon and learns that the Soo-hong's grudge was not against Ja-hong but rather Dong-yeon and Lt Park. He finds that Soo-hong has been accidentally killed while on guard duty by his partner Dong-yeon, and his death was covered up by their superior, Lieutenant Park. Gang-rim determines that it is Ja-hong's brother Soo-hong who has become the vengeful spirit. The evidence is thrown out and the charges are dismissed. And that the letters to Ji-Yeon, despite her actually understanding that her father was dead, helped her cope with her loss.

Gang-rim supernaturally links with Deok-choon from the living world to defend Ja-hong, stating that Ja-hong had also written fake letters to his mom to cheer her up, allowing her to focus on her health. In the Hell of Deceit, Ja-hong is accused of writing fake letters to the family of those who had died, one of whom is Ji-yeon, the daughter of his fallen colleague. Gang-rim leaves the party to investigate as the rest proceeds. This change indicates that a member of Ja-hong's family had died and become a vengeful spirit. On the way to the Hell of Deceit, ghouls attack as the physics of Hell begins to morph. Ja-hong blurts out that he only worked for money and was about to be punished when Gang-rim interjects, stating that the money was to support his brother and ailing mother and therefore acquitting him.

In the 2nd court, Hell of Indolence, Ja-hong's guardians presented his selflessness and diligence. After rescuing 8 others, Ja-hong attempted to go back for his colleague only to be held back as the building collapsed. About to be sentenced, it is revealed that his colleague told him to prioritize the civilians. In the first court, Hell of Murder, Ja-hong is tried for the indirect murder of his colleague, who was trapped beneath rubble during a fire. If he passes, he will be reincarnated and his guardians will be given credit towards their own reincarnation. They are to escort and defend him in seven trials in 49 days. Firefighter Kim Ja-hong ( Cha Tae-hyun) dies in the line of duty and is escorted to the afterlife by three guardians: Hae Won-maek ( Ju Ji-hoon), Lee Deok-choon ( Kim Hyang-gi) and their leader Gang-rim ( Ha Jung-woo).
