Shiva (シバ, Shiba)
Shuu's young son and member of the resistance army. To spare his son from the tragic fate of the Jinsei (Star of Benevolence), Shuu opted not to teach him Nanto Hakuro Ken. However, with his father's blood flowing within him, Shiva was destined to sacrifice himself for the greater good. He rescued Kenshiro from the clutches of Souther and used himself as bait to distract Souther's troops, performing a suicide attack with dynamite sticks.
When Shuu regained his eyesight, he remarked that he could see a resemblance between Kenshiro and Shiva.
