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!
Come to think of it, 
zoos are out of the ordinary, right?
على ذكر الأمر، حدائق الحيوانات غير اعتياديّة، صحيح؟
Sag mal, ist ein Tierpark
nicht etwas Außergewöhnliches?
Ir al zoológico es algo
fuera de lo cotidiano, ¿no?
Ir al zoo es algo
fuera de lo cotidiano, ¿no?
Un zoo, c’est déjà un peu
hors du commun.
Ora che ci penso,
gli zoo sono piuttosto fuori dall'ordinario, no?
Pensando bem, zoológicos
são fora do comum.
Кстати, зоопарки ведь 
не самый обычный досуг.
