A group of anime characters lie in a pile, then the scene cuts to a smiling girl with blue hair, followed by a close-up of a character with black hair and blue eyes, then a close-up of a red and white Santa hat, then a close-up of a character's face with snow falling, and finally a character with long black hair is seen from behind, reaching out with one hand in a dark, grassy area.
