The Amusement Club is cleaning the club room in preparation for new students and perhaps new members.  Opening a mysterious closet they discover a device that sends Akari back in time, with she takes as a chance

pero antes quiero gritar a los cuatro vientos lo que siento.
Mas eu quero confessar esses
 importantes sentimentos
