Soul Crossing Notes

In this world, there are too many people who died inexplicably. Carrying unspoken resentments and unresolved obsessions, they refused to step into the door of the underworld, and thus stayed in the world, becoming lonely ghosts that lingered. There is another group of people who stand in the gap between the Yin and Yang worlds, doing errands that are unknown to others. They do not catch ghosts or exorcise evil spirits. They only rely on their ability to transfer souls to invite the souls trapped in the world back to where they belong, eliminate their obsessions, and send them on the road to reincarnation. This group of people is called - Soul Crossers.
