The Secret United Earth Defense Force. The first and last line of defense against any and all extraterrestrial beings that would dare threaten the peace and sanctity of the human race. With the latest cutting-edge secret weapons and the bravest and strongest soldiers humanity has to offer, all aliens that come bringing false claims of friendship and harmony have been bravely vanquished by the glorious Secret United Earth Defense Force. Until today. Chasing an unimaginably fierce and vicious magical beast across time and space, the greatest of the bringers of justice and freedom to the galaxy, Ultra Mahou Shoujo Manana arrives in Earth, unfazed by the full military strength of the Secret United Earth Defense Force. Here she meets the ordinary Japanese teenager Shunichi, a young timid boy who is graphically crushed by the magical beast as it lands, his bright red blood and guts splattering across the road, the broken shards of his bones the only solid remains of what was left of this once bright and vivid young man. But the Secret United Earth Defense Force is not feared across the planet as the mightiest military force known to man for nothing. Not to be thwarted so easily, they gather the full might of the combined human armies, destroying any who dare to defy their authority, and raise their banners and power up their giant death robots, ready to destroy these filthy alien scum once and for all. Will their forces be sufficient to overwhelm Manana’s full magical power? Will the magical beast bring death and destruction to the city? Will Shunichi finally confess to his one true love, the outgoing tomboy Anna? Only time would tell.
