It was another peaceful evening at Audire. The jazz tunes playing in the bar, along with the cocktail you had just finished, made you doze off, and you did your best not to succumb to sleep. The sound of the door opening roused you from your drowsiness. The man who had just entered was Ryukosuke Yuze, a regular at Audire whom you had met a few days earlier. 'Good evening,' he said to you, wearing his usual serious expression.
