The Ryu System (リュウ座系 Ryū-Za-Kei, Dragon System) is the star system from which Shou Ronbou heralds from. As one of the 88 Constellations, it is part of the space dominated by the Space Shogunate Jark Matter, with its power embodied by its very own legendary Kyutama and Voyager wielded by the native Kyuranger warrior.
