It's the day of the St. Cherrine Academy field trip! Meguru and her friends are all excited about their trip to Okinawa, but things get even better when they happen to run into the idol group, The Twenty-Eights! After helping with their event during the day, Meguru earns an invitation to their concert that night.
From across the ocean 
that envelops the world!
!من وراء المحيط الّذي يلفّ العالم
Von der anderen Seite des
die Welt umspannenden Ozeans!
Cruzando el océano que rodea el mundo.
Cruzando el océano que rodea el mundo.
Al di là dell'oceano che ricopre il mondo!
Do outro lado do mar,
envolvendo o mundo!
Из-за океана, что омывает весь мир!
