There were even rumors that the recent happenings in the Yamaguchi-gumi were all the work of the future heir of the Green Gang. Otherwise, how could the heir of the Green Gang have arrived in Japan? The leader of the Yamaguchi-gumi, Yamaguchi, had been shot for a long time and almost lost his life due to excessive blood loss. There were also people from the Yamaguchi-gumi who were attacked with drugs by unknown people.
Even though the Yamaguchi-gumi who had been poisoned by the medicine powder did not die in the end, it was not any better than death. Some of them were completely disfigured, while others had anorexia. However, Dr. Oada from the Yamaguchi-gumi was helpless against all of this. In any case, the rumors about the successor of the Green Gang were all very mysterious.
