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!
I'll do my best to keep on 
growing, right up until
سأفعل ما بوسعي للاستمرار في التطوّر
Auf diese Weise will ich
bis zum Festival weiter wachsen.
Quiero seguir creciendo cada día
hasta el festival.
Quiero seguir creciendo cada día
hasta el festival.
Je vais faire en sorte d’évoluer
Farò del mio meglio per continuare a crescere,
Vou continuar crescendo sem parar
Каждый день вплоть 
до фестиваля полнолуния
