A-Ko is a lively seventeen-year-old, no different from any other student except for the fact that within her diminutive frame, and 'sailor outfit', lies a strength that can only be described as superhuman. Student cuties A-Ko, B-Ko, and C-Ko have a lot of problems in store for them besides being late for class. A-Ko will need every bit of her power to fight off her teenage rival, not to mention a monstrous alien spaceship hurling towards Earth in search of...? One of the running gags thoughout the show is that everyone is a girl, even if they look like a boy, they are a girl. This is a parody of all things anime, action packed and full of fun that will take your breath away.
