Shintaro himself is known to be exceptionally intelligent and capable, to the point that many in the Yamazaki Syndicate believe that he should be their leader. However, Shintaro is a staunch believer in the rules and traditions of the Yamazaki Syndicate to a fanatical degree. As shown, Shintaro is extremely devoted to his twin brother Shingen. Having brutally rejected the offer from the three Branch Family Heads of the Yamazaki Syndicate to become the new head of the clan due to his brother's lethargy and proceeded to brutally execute them for betraying the traditions of the syndicate. While acknowledging that his brother's lethargy is detrimental to the organization as a whole and that him taking over the syndicate would benefit and restore the syndicate to its former glory, Shintaro nonetheless continues to insist on following the rules of the syndicate despite the group's degradation and weakening as a whole. A serious man who places the rules of the Yamazaki Clan above all else, even ordering a young Gun Park to kill his son for discouraging him from becoming the next Clan Head. As noted by the branch family leaders he executed, ordering the death of his own son had a deeper psychological effect on Shintaro than he initially believes and he may feel subconscious remorse for having done so and has led him to become fanatical in following the traditions and rules of the Syndicate. Later, upon learning the truth about his birth, he completely mentally breaks down and kills Shingen to become the head of the family.
