Childhood friends Aoi Satsuki and Arata Uzuki are tasked with producing a fan event as part of a TsukiRadi project. Aoi, the considerate and kind prince of Gravi, selects "adventure" as the event's theme.

Believing adventurousness to be something he lacks, Aoi works extra hard to come up with an event concept with Arata. The answer they arrive at is a puzzle/escape room at the zoo that will give guests a taste of the extraordinary. The younger members take on the role of the guests as they begin rehearsing for the event!
Isn't it going to be a little tough 
without the extras, though?
لكن ألن يكون الأمر صعباً دون ممثّلين ثانويّين؟
Aber für die nächste Szene brauchen wir
doch auf jeden Fall einen Statisten.
Pero será muy difícil hacer
esa escena sin extras, ¿no crees?
Pero será muy difícil hacer
esa escena sin extras, ¿no crees?
Mais ça va pas être facile,
sans les figurants…
Però non sarà un po' complicato, senza le comparse?
Não é meio complicado sem os figurantes?
Без массовки трудно будет, нет?
