A man awakening. His body doesn't seem to move as he thought. A man approaching there. A man trying to escape with his motionless body. Someone is slowly chasing him. Soon, the murder weapon falls on the man. Yoichi Sakai, a freelance video director, feels stuck in a deadlock as he barely maintains his current situation every day due to meticulous work. When he returned to the apartment that serves as his home and office, he received a bag and a letter. The letter reads, "Can you record my activities? Please contact me once. I think you will be interested." Then, Sakai, who is busy with work, opened the bag with a relaxed mood and was shocked. There was a human finger inside. "......!" He said something wrong. Although he wanted to call the police, he stopped before that and fell into deep thought. "This will be an opportunity to change my life..." With such a premonition, I decided to contact the contact information written on it.
