Gintama

A large, round, brown object with a textured surface falls from the sky above a traditional building with a tiled roof and green trees, then the scene cuts to a character with long black hair, a mustache, and a red hat with a white 'M' symbol, who adjusts the hat with his right hand, followed by a scene of soldiers on horseback firing rifles, then a close-up of a character with silver hair and a calm expression, and finally a close-up of two characters with spiky hair facing each other with intense expressions.
