Six Gravity (AKA Gravi) and Procellarum (AKA Procella) both belong to Tsukino Talent Production (AKA Tsukipro).

Gravi continues to expand their range of activity as Tsukipro's top group and sets their sights on the joint concert Full Moon Festival 2020 as their next goal. Kakeru Shiwasu and Kisaragi Koi are tasked with recording comments from the group's members hyping up the event.

Choosing "a new me" as their theme, the two boys enthusiastically search for filming locations and set up a schedule for their comment video recording tour, but will it end without incident...?!
Procella can't sit back while 
Gravi is working this hard.
لا يستطيع بروسيلا الوقوف مكتوفي الأيدي
بينما الجذّابون يعملون بجدّ
Wenn Gravity das macht,
dann müssen wir auch mitmachen.
Procella no puede relajarse
con Gravi esforzándose tanto.
Procella no puede relajarse
con Gravi esforzándose tanto.
Où Six Gravity ira,
Procellarum suivra.
I Procellarum non possono stare a guardare
mentre i Six Gravity lavorano sodo.
Procellarum não pode ficar de braços cruzados
enquanto o Six Gravity trabalha tanto assim.
Процелле нельзя отсиживаться,
пока Грави так стараются.
