Child of Destruction is the next installment in the RIKI-OH series, which follows the Wall of Hell OVA. This entry provides further insight into Riki's background by taking us back to his childhood and revealing his tragic journey - from the loss of his mother to the moment he became separated from his twin brother Nachi during a game of hide-and-seek. For years, Riki has been haunted by Nachi's voice calling out to him, "Are you ready yet?" Riki bears a six-pointed star symbol on his hand, while Nachi's hand displays a swastika emblem with an unknown significance. As the story unfolds, Riki finds himself in Misaki, a town overrun with illegal nuclear power plants and controlled by a military group called "God's Judgment." Trapped and forced to fight in violent, gladiatorial matches in a massive arena, Riki eventually reunites with his brother, who is also known as "Savior" for his incredible abilities. However, their reunion is far from joyous, as Nachi holds deep resentment towards his sibling. Compared to the first installment, Part 2 of the series presents a much bloodier and violent spectacle, featuring Riki unleashing his rage on numerous enemy soldiers.
