In the dystopian kingdom of Urunaria, the higher you live, the more you’re worth. From the bold mind of Roku Souna - a gripping sci-fi debut where one boy dares to rise against a world built to keep him down. In the towering kingdom of Urunaria, society is literally built on inequality. The wealthiest reside at the top, while the poor are confined to the dark, crumbling depths below. For Kuro, a young slave raised by his uncle in the lowest levels, life offers no future - only labor, loss, and silence. But when his uncle is executed by the state, Kuro inherits a mysterious device: Gizmo - a pair of mechanical gloves with the power to grip, scale, and defy the very system built to crush him.
