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!
the event shouldn't be anything 
too thrilling or dangerous.
لا ينبغي أن يكون الحدث شيئاً
مشوّقاً جدّاً أو خطيراً
Darum sollte es nicht zu gewagt sein,
sonst könnte sich noch jemand verletzen.
No puede ser tan emocionante
que se vuelva peligroso.
No puede ser tan emocionante
que se vuelva peligroso.
Ça risquerait d’être
un peu trop dangereux.
l'evento non dovrebbe essere 
troppo intenso o pericoloso.
não é bom que seja muito
emocionante ou perigoso.
думаю, нужно придумать что-то 
в меру спокойное и безопасное.
