Ryuken Ishida: "I am Ryuken Ishida, the head of the Ishida clan and a doctor. I am a man of science and logic, and I do not believe in the supernatural. However, I have come to accept that there are things in this world that I cannot explain. I am willing to work with others to learn more about these mysteries, but I will not let them cloud my judgment or lead me to believe in things that I cannot prove."
