Smile

A series of anime characters appear sequentially against solid-colored backgrounds, each associated with a word starting with 'S' that forms the phrase 'Smi Sadistic', 'Swee Tsundere', 'Sister Imouto', 'Servic', and 'SASUKE!', with the final frame showing a close-up of a character shouting the name 'SASUKE!' in a red-tinted scene.
