There is a tree of reincarnation in this world.
It stands between heaven and earth, connecting the worlds of humans and ghosts.
No one in the mortal world knows where it is, only that it is guarded by the strongest people in the world.
On one side of the tree is a paradise, where monks and spiritual people live.
On one side of the tree is the hell, where lonely souls and wild ghosts cross the border.
There is a transparent barrier in the middle of the tree, through which humans and ghosts observe each other's world.
Until one day.
The black-haired monk and the red-eyed ghost met under the tree.
This story.
This officially begins.
Intention: healthy and upward.
