As Dr. Akira and Christy left the hospital, they shared a laugh, knowing that their bravery and determination had solved another mysterious case.

Suddenly, a ghostly figure materialized before them. It was the spirit of a former patient, who had died under mysterious circumstances. The patient, a young woman named Sarah, began to communicate with Dr. Akira and Christy.

The duo began to investigate, searching for any logical explanation. They stumbled upon a room with a peculiar symbol etched into the wall. Dr. Akira, being an expert in various medical fields, recognized the symbol as an ancient ritualistic marking.
