On an artificial island, fourteen-year-old Akane Isshiki lives a quiet, content life with her practical younger sister Momo and their brilliant inventor grandfather. When the sky is clear, the island’s residents can see the Manifestation Engine just across the water-the revolutionary invention that once ended the world’s energy crises and ushered in an era of peace. But that peace shatters when a mysterious force known as the "Alone" emerges without warning, threatening to destroy the Manifestation Engine and upend their tranquil existence. Armed with powerful Palette Suits crafted by her grandfather, Akane and her friends must stand together in the face of this crisis. Their bond may be the last hope to protect their world.
