The Genryū are five legendary dragons that appear in Naruto Shippuden: Dragon Blade Chronicles. Each Genryū represents the five elemental natures: earth, water, wind, fire, and lightning. Before the First Shinobi World War, the Genryū fertilised the land belonging to the Ryū clan. If all five of the Genryū are merged together, they form the Light Dragon, capable of destroying the world. Kuroma Tatsushiro seeked to become the Light Dragon to seek revenge on those who hate him and his sister Akari Tatsushiro from being descendants of the Ryū clan and destroy the world.
