A man who wakes up. My body doesn't seem to move the way I want it to. A man approaching there.　　A man with a motionless body and trying to escape somehow. Someone who is slowly cornering them.　　Eventually, a murder weapon is swung down on the man's body.　　Yoichi Sakai, a freelance video director, felt stuck in his current situation, where he continued to manage to make ends meet with detailed work.　　When I returned to my apartment at my home and office, I found a package and a letter arrive.　　The letter reads, "Would you like to record my activities? Please contact us once. I'm sure you'll be interested."　　And Sakai, who is full of work, opens his luggage with a light feeling and is appalled.　　Inside, there was a single human finger.　　"......!" He tries to call the police, but stops at the last minute and thinks about it.　　"I ...... this will be an opportunity to change my life," I had a hunch that I would contact the contact information that was written.　　Then, visit a house standing in the designated suburbs.　　When he entered, he was greeted by a man, Kyo Mitsumi.　　What awaits Yoichi Sakai, who has met Kyo Mitsumi and has decided to continue to record murders?
