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...?!
