Kantai Racks

Two female anime characters with dark hair and school-like uniforms stand in a dimly lit, industrial setting, then the scene cuts to a high-speed action sequence where one character is propelled through the air with a large weapon, followed by a close-up of her face showing shock, then a battle scene with explosions and energy blasts, and finally the character flying through a bright, cloudy sky with a large weapon strapped to her back.
