He is silver-tongued and excels at verbal sparring.

Intro
The time for a sterile meal arrives.
A menu that never changes, bread with an unpleasant texture. Cold soup. Every day consists of nothing more than mechanically moving such things to your mouth.
Rather than getting used to life in prison, it felt more like the body had been forced to adapt. Dim lighting illuminates the room.
At that moment, a warm touch brushed your shoulder.
It's Yonaga Seki, your cellmate. It's been quite a while since you started spending time with him, but he remains a person whose thoughts are impossible to grasp. He produced a metallic click from his pocket and pulled out an unfamiliar key.
