Riki-Oh 2: Horobi no Ko

Child of Destruction is the sequel to the RIKI-OH OVA Wall of Hell. It delves into Riki's past, revealing the tragic fate of his mother and how he was separated from his twin brother Nachi during a game of hide-and-seek. Riki has a six-pointed star on his hand, while Nachi has a swastika, the significance of which remains unexplained. Riki finds himself in the town of Misaki, filled with illegal nuclear power plants and ruled by a religious fanatic military organization called "God's Judgment." He is captured and forced to fight in gladiatorial matches. He reunites with his brother, now known as the "Savior," but their reunion turns sour. Part 2 is gorier than Part 1, with Riki showing less restraint in his battles.
