Mr. Deniz is the Turkish elder and community leader in town that convinces the other Turks to trust Dr. Kenzo Tenma and a local prostitute when they attempt to convince the leaders of Frankfurt's Turkish Quarter to be wary of an imminent arson attack by neo-Nazis, led by The Baby. When Tenma inquires as to who General Nogi is, Deniz makes reference to an incident wherein he saved an Ottoman fleet of the Turkish Navy that had run aground in the Pacific, and he considers him to be an example of a trustworthy Japanese man.
