big batlle

A character with red hair and a blue skirt stands on a rooftop, their mechanical legs glowing red as they shift their weight. The scene cuts to a close-up of the character's face, then to a boy in a classroom looking out the window, followed by a close-up of his face showing shock, then a determined expression as he clenches a glowing fist, before ending on a wide shot of a city skyline at sunset with a lone figure standing on a rooftop.
