A-ko is pure 80s absurdist energy compressed into 90 minutes: a girl with impossible strength fights her jealous classmate over their mutual friend while an alien armada literally arrives to ruin the day. The movie treats a magical girl love triangle and an alien invasion with the exact same comedic deadpan, so you're never sure if the next scene will be slapstick or genuinely spectacular. It knows exactly what it is, a gorgeous, ridiculous, unapologetically fun action-comedy that doesn't waste a second pretending to be anything else.
A-ko wakes up ready for another day at school in the gleaming metropolis of Graviton City, but her cheerful routine with her spacey best friend C-ko gets upended fast. B-ko, the ruthless daughter of a mega-corporation, has decided she wants C-ko for herself and won't take no for an answer. She's got money, influence, and a mechanical edge that she's not afraid to use. Meanwhile, an enormous alien battleship descends on the city with demands of its own, and everyone suddenly becomes a target in the crossfire. A-ko discovers she's more than just another student: she possesses superhuman strength and speed that let her hold her own against ridiculous odds. What unfolds is a high-octane collision of teen drama, robot-powered combat, and interstellar chaos as A-ko fights to keep her friends safe and figure out why everyone in the galaxy seems focused on their little corner of the world. It's colorful, fast, and totally ridiculous in the best way.
