Attack on Titan

A young man with dark hair and a determined expression looks down from a high vantage point, then the scene shifts to a chaotic battle where a man in a green cloak fights a giant humanoid creature, followed by a figure in a dark cloak moving swiftly through a snowy environment, and finally a character in a brown coat glides through the air on a mechanical device, all set against a backdrop of a city with tall buildings and a bright blue sky with scattered clouds.
