Part 3/9:
Within the spirit realm, Yuka's case presents a puzzling situation for the administrators. He does not fit into the conventional categories of Heaven or Hell due to the noble nature of his death. A spirit world leader named Yama sees potential in Yuka and offers him a chance for reincarnation—on the condition that he assists the spirit world as a detective, exploring cases linking demons to the human world.
One of Yuka's first assignments is to unravel a bizarre situation revolving around a curse named Mou Chong, which had influenced the driver responsible for his death. Although initially resistant, feeling more like a burden to his mother than a hero, Yuka's journey starts here, leading him into dangerous waters as he navigates both the spirit and human realms.
