Attack on Titan

A young man with dark hair and a determined expression looks forward, his face illuminated by glowing particles in a dimly lit environment. The scene cuts to a close-up of a man with a wide, confident grin, followed by a view of a city street with a large explosion in the sky. A man in a dark outfit is seen leaping through the air, then a figure in a white coat throws a grenade, causing a massive explosion. The sequence ends with a close-up of a long object, possibly a weapon, lying on a table as a bright light flashes from the left side of the frame.
