"Professor, someone from the Tokyo District Public Prosecutor's Office is here again." Chen Yu was writing in his office when his secretary Shirai Reina knocked on his door from outside.
"Let them in." Chen Yu looked up, set aside his pen, and had a premonition about the Tokyo District Public Prosecutor's Office's visit.
With Chen Yu's permission, two people from the Tokyo District Public Prosecutor's Office soon appeared before him. After showing their credentials again, they said, "Professor Chen Yu, in regard to Takashi Rokkou, whom you are treating, we have some matters we need to inquire about with him. May we speak to him now?"
