盲目の老人

A blind elderly man from Munich who knew Johan as a child and voluntarily explained to Dr. Tenma how interesting the boy was. He told Dr. Tenma that Johan admired him because he had saved his life, making him more significant to Johan than his parents.
The old man informed Dr. Tenma that Franz had stayed with the Haynau couple from March 1987 to April 1988. He described Franz as highly intelligent and polite, noting that the boy quickly mastered English and French under his guidance. Franz was also greatly amused by the old man's war stories, particularly the account of his escape from death when a U-boat was attacked by an Allied destroyer. He showed interest in human behavior on the brink of death and the fear it provoked. The old man also stated that Franz would not open his heart to anyone except his sister. When Dr. Tenma mentioned he was searching for the boy's twin sister, the old man said Franz would go to pick her up in Heidelberg when she turns twenty.
