Ultra Mahou Shoujo Manana Vol.1

Earth's Secret United Earth Defense Force has long stood as humanity's bulwark against extraterrestrial invasion, their arsenal of advanced weapons and elite soldiers repelling every alien threat with decisive force—until a powerful magical warrior named Ultra Mahou Shoujo Manana arrives in pursuit of a ferocious interdimensional creature, overwhelming the military's defenses with ease. When the beast's arrival devastates the quiet Japanese city where ordinary teenager Shunichi lives, the global military machine mobilizes its full might, deploying colossal mechanized war platforms in a desperate bid to contain the alien threat before it levels everything in its path. Caught between the escalating conflict and his own quiet struggles, Shunichi must navigate both the chaos of the invasion and the complications of his feelings for the spirited Anna, as the fate of the world hangs in balance.
