One night, Dr. Yananaka (psychiatrist) came to the office of Dr. Watanabe (surgeon) in Teikoku University Hospital. He asked Dr. Watanabe for removing the tumor on his left kidney right now. Otherwise, it will copy Yamanaka's genes and destroy himself. Dr. Watanabe made the operation team with Usui (anesthesiologist) and Eguchi (pathologist) who still had been in hospital.
