Gekitotsu no Hexennacht

The world is held in the iron grip of the Black Witch, a malevolent force sealed away upon the moon. Her confinement is not absolute; she can only be confronted and judged once every ten years during the fateful night known as Hexennacht. To stand against her overwhelming power, humanity relies on chosen magical girls—elite warriors who have proven their worth by emerging victorious from grueling battles against one another. Only the strongest among them are granted the right to face the ultimate threat looming over the earth. Among these exceptional fighters is Horinouchi Mitsuru, the proud representative of Eastern Japan, who relentlessly strives to become the most powerful warrior alive. Her path takes an unexpected turn when she encounters a mysterious girl named Kagami Kagami, a stranger wielding strange and unfamiliar abilities. Their meeting sparks an intense clash between two formidable forces, igniting a fierce rivalry that transcends mere competition. Bound by destiny and driven by unwavering resolve, these young women must channel their own extraordinary powers into a singular purpose: to save the world from impending destruction before the decade's final night fades away.
