“The best tug…”

A character with black hair and a school uniform stands in a dimly lit room, then the scene shifts to a traditional Japanese room where the character stands on a platform before a crowd of large, round, white figures, followed by a transition to a stage with a disco ball and the same character on a platform, then a close-up of the character's face with a slight smile, and finally the character standing in a city street with a wide smile.
