The homeless god

A black screen transitions to a close-up of a smiling anime character with dark hair and a light scarf, who says "I'm a god," followed by a scene of a girl in a plaid shirt walking through a colorful indoor amusement park, then a character in a checkered outfit reacting in shock with a crackling energy effect, and finally a close-up of a different character with short dark hair and a light scarf looking surprised, before the screen returns to black.
