Giovanni is the leader of the Wolf Pack gang. He is fair when it comes to fighting. This was proven when Giovanni and his companions fought with the Black Brothers. Before their fight began, he told everybody that using any kind of weapon is not allowed. But Tachioni, one of the members of the Wolf Pack, disobeyed. He drew a blade and tried to kill Romeo. Because of this, Giovanni accepted the defeat of the Wolf Pack gang in their fight against the Black Brothers. Later on in the series, Giovanni and his companions became more supportive for the Black Brothers. In the last episode of the anime, Giovanni and the rest of the members of the Wolf Pack gang decided to make peace with the Black Brothers.
