Blue Phobia

ブルーフォビア

On a remote island, prisoners are forced to mine a mysterious ore known as sea sapphire, prized as a potential energy source. Prolonged exposure to the substance triggers a horrific transformation called indigopathy, gradually turning skin and bone a deep blue and eventually petrifying the entire body into ore. The mining prison is converted into a research facility where the afflicted are treated as mere test subjects.

One day, a man with no memory of his identity awakens strapped to an examination table. His panic is interrupted by a sudden rescue from a girl whose hair and limbs are completely blue. She calls him Kai and insists he promised to escape the island with her, setting them on a desperate flight from the facility's clutches.

The story follows Kai and his enigmatic savior as they navigate the dangers of the island, grappling with the secrets of the blue ore, the true nature of the experiments, and the fragments of Kai's lost past.
