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!
If you do, I'll admit defeat 
and leave this place.
إن فعلتم فسوف أعترف بالهزيمة وأغادر هذا المكان
Wenn ihr diese Aufgabe lösen könnt,
Si lo consiguen,
admitiré mi derrota y me iré de aquí.
Si lo conseguís,
admitiré mi derrota y me iré de aquí.
Si vous y parvenez,
je me retirerai et disparaîtrai.
Se ci riuscirete, ammetterò la sconfitta
e me ne andrò da qui.
Se conseguirem eu admito
minha derrota e saio.
Сможете — и я уйду, признав поражение.
