A small meeting was held in the first class of the second grade of high school, and a murder tragedy suddenly emerged. Who among us was the murderer, or was it an inexplicable "him"? Tragedies happened one after another, and the number of people was gradually decreasing. I began to couldn't help but believe that the devil is really in the world. The murderer may be any of us. How can we end this sudden killing...
