Kei breaks reality by accident and spends 35 episodes trying to glue it back together while entire civilizations fold in and out of existence around him. The show treats dimensional collapse like a wound that never stops bleeding, not a puzzle with an answer. You watch a pilot slowly realize that saving the world might mean erasing people who only exist because he failed.
Kei Katsuragi is a pilot caught in the middle of a global war that's grinding humanity toward extinction. When his military superiors order him to deploy a reality-warping weapon as a last-ditch gamble for victory, he follows orders without hesitation. The detonation succeeds, but not in any way anyone anticipated. Instead of destroying the enemy, the bomb tears holes in the fabric of existence itself. Multiple dimensions, alternate timelines, and parallel realities begin colliding and bleeding into one another, transforming the world into a chaotic patchwork of impossible geographies and physics. Now Kei finds himself piloting a transforming mecha across fractured landscapes, desperately searching for a way to seal the dimensional rifts before reality collapses entirely. He's joined by a growing crew of misfits pulled from different worlds, each with their own stakes in preventing total annihilation. The war that seemed so important moments ago becomes irrelevant when the very concept of reality hangs in the balance. Super Dimension Century Orguss blends high-octane mecha action with dimension-hopping sci-fi adventure, creating a world where nothing stays stable for long.
