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!
It might be the most alien 
thing imaginable to you.
قد تكون أكثر شيء غريب يمكن تخيّله بالنسبة لك
Damit hast du scheinbar
überhaupt nichts am Hut.
Quizás sea algo muy ajeno a ti, Aoi.
Quizás sea algo muy ajeno a ti, Aoi.
C’est à des années-lumière
de ta vie.
Potrebbe essere la cosa più lontana 
dalla tua quotidianità.
Deve ser a coisa mais estranha
possível para você.
Возможно, самая далёкая 
от тебя вещь в мире.
