Aqua

A light blue-haired girl in a blue and white outfit shouts encouragement to a brown-haired boy in a green and white outfit, who reacts with a shocked expression; the scene cuts to the girl looking determined as she speaks, then to a dark-haired boy screaming in frustration, followed by a shot of the girl falling backward with the text "Aqua" and "She's still Useless!" overlaid, all set against a snowy landscape and a dark, stormy sky.
