When a mysterious Dimension Rift suddenly opened in the heart of Tokyo without warning, the world was plunged into unimaginable chaos. Terrifying, colossal monsters from nightmares and human fantasies began tearing through reality, spreading terror and destruction wherever they roamed. Modern military weapons proved powerless against these otherworldly forces, pushing humanity toward the brink of destruction as the rifts continued to emerge, unleashing increasingly powerful and horrifying creatures. Amidst the turmoil, Haruto Mori and Kanna Fujita, two ordinary university students, find their lives forever changed when they are chosen by ancient Sacred Madougu artifacts. Guided by Luna, an enigmatic Astral Guardian who appears as a peculiar one-horned white cat with fragmented memories, they awaken as Madougu Wielders—endowed with extraordinary abilities to battle the monstrous beings from the Rifts, known as Chaos. Their journey begins at Sakamiya University, where their first trial awaits: to close the Dimension Rift by defeating the monstrous Boss guarding it. But this is only the beginning. To stand a chance against the growing threat, they must find seven others from diverse walks of life, each destined to wield their own Sacred Madougu. As the Japanese government forms the specialized military division JSF-RIDOS to assist the Madougu Wielders, new threats and mysteries surface. A mysterious powerful time-stopper spirit girl emerges, and an ancient, sinister secret buried for over 10,000 years begins to unravel. With hundreds of Madougu artifacts scattered worldwide reactivating alongside the Sacred Madougu, humanity's destiny becomes intertwined with these mystical relics. Haruto and his allies face not only the Chaos but also the darker side of humankind. Many who discover Madougu gain powers of their own, igniting conflict and ambition that threaten to fracture the fragile balance of survival. Can humanity rise above its own flaws and defy its destiny of destruction? Or will eternal chaos consume everything, leaving only ruin in its wake? — — — — —
