Those who want to forget their loneliness. Those who want to satisfy their desires. And then――those who, despite possessing enormous wealth and power, can never be satisfied. The first to appear was Soji, a young entrepreneur renowned in the IT industry. He was a man who would look at people with an appraising gaze while swirling expensive wine. As if he believed he could calculate even the human heart with numbers.
