Once upon a time, I met a demonic angel,
Once upon a time, I met an angelic devil,
Once upon a time, those were stories from long ago.
A long time ago, the priest met the boy.
Later, the boy grew up and left the town. He returned five years later, but died unexpectedly.
However, things did not end there. The priest disappeared and his body was found.
Terrifying rumors spread quietly in the darkness.
Angel-like boys, twins with very different personalities, blood-stained yellow roses, unsolved cases from many years ago,
Their fates are intertwined, and the terrifying devil hides in the town.
