ready to go

A girl and a boy stand back to back in front of a bright window, their long hair flowing as they turn to face each other. A young man with red hair looks off into the distance, followed by a boy with black hair unleashing a burst of fire from his hand. A man in a military-style uniform smiles confidently, then a character with spiky pink hair and another with spiky blonde hair clash in a fiery battle. The sequence ends with a close-up of a young man with dark hair and wide eyes, looking shocked.
