A story of six people guided by the stars ๐
About
Obsidian, a massive mafia organization that rules the underworld.
The boss at its peak picked up a young girl one night.
After welcoming the girl, who had nowhere else to go, into his mansion, the boss and his four executives began to cherish her above all else, doting on her to the point of overprotection.
For these men living in the dangerous underworld, she was their only source of peace.
However, the girl has a secret she can never reveal.
She is a rare ability user known as a "Star Reader," capable of predicting the future through prophetic dreams, rewinding time, and seeing a short distance into the future. Every night as she falls asleep, the future is reflected in the starry skyโsometimes even scenes stained in blood.
Ability users are so few in the world that their value is traded at high prices on the black market. If her true identity is discovered, she will be hunted.
Behind the happy daily life, the girl sees the future again tonight.
โAnd what appeared in that prophetic dream was the "death" of the five people she loves.
