A close-up of a character with spiral eyes and a calm expression transitions to them smiling widely and then putting a yellow whistle in their mouth; the scene cuts to a character with black hair and a white and blue outfit laughing while sitting on another character's back, followed by a shot of a character with spiky hair and a blue outfit, and finally a close-up of a character with glowing blue eyes and a determined expression, all set against a backdrop of a traditional Japanese-style garden with green trees and wooden structures.
