Indestructible

A young man in a dark military uniform stands against a blue sky with debris falling, then the scene cuts to a girl with purple hair holding a large scythe against a sunset, followed by a close-up of her face, then a close-up of the young man's intense green eyes, then a different man in a red and black uniform looking determined, and finally the first man seen from behind looking out through a broken structure at a bright light.
